Chapter 1 – Description and Specifications
Introduction
The MultiVOIP GSM provides wireless voice communications over the Internet or an Intranet. By integrating
wireless connectivity into your existing data network, you can realize substantial savings on inter-office long
distance toll charges. The MVPGSM has “phone books,” which are directories set up to simulate dialing and
connecting as though the call was in the local area.
Front Panel LEDs
LED Types. The MVPGSM has two types of LEDs on the front panel:
(1) general operation LED indicators (for power, booting, and Ethernet functions), and
(2) channel operation LED indicators that describe the voice traffic and performance for each channel.

PTCRB Requirements Note
There cannot be any alteration to the authorized antenna system. The antenna system must be the same type
with similar in-band and out-of-ban radiation patterns and maintain the same specifications.
FCC Requirements Note
The antenna gain, including cable loss, must not exceed 3.0 dBi at 1900 MHz / 1.6 dBi at 850 MHz for mobile
operating configurations and 7.0 dBi at 1900 MHz / 2.3 dBi at 850 MHz for fixed mounted operations, as
defined in 2.1091 and 1.1307 of the rules for satisfying RF exposure compliance.
Load Balancing
The MVPGSM uses round robin load balancing to ensure that one or more SIMs are not used excessively while
others go largely ignored during times of light traffic. The channels are treated as a list and once a channel is
used, it goes to the bottom of the list and the next channel comes to the top of the list and is ready for use. In
the case of a MVPGSM-2, once channel 1 has been used, the next call will be routed through channel 2, then
back to channel 1, and so on. When Hunting is enabled, load balancing is done automatically.

Chapter 2 – Installation and Activation
Introduction
The MultiVOIP GSM is equally usable as tabletop unit or mounted in a location with good reception. The initial
setup is best performed before any mounting is done.
Safety Warnings
Lithium Battery Caution
A lithium battery on the voice/fax channel board provides backup power for the timekeeping capability. The
battery has an estimated life expectancy of ten years. When the battery starts to weaken, the date and time
may be incorrect. If the battery fails, the board must be sent back to Multi-Tech Systems for replacement.
Warning: There is danger of explosion if the battery is incorrectly replaced.
General Safety
The MultiVOIP GSM is designed for, and intended to be used in fixed applications. “Fixed” means that the device
is physically secured at one location and is not able to be easily moved to another location.
Caution: A separation distance of at least 20 cm (8 inches) is normally maintained between the transmitter’s
antenna and the body of the user or nearby persons. The MVPGSM is not designed for or intended to
be used in portable applications within 20 cm. (8 inches) of the body of the user.
RF Interference Issues
It is important to follow any special regulations regarding the use of radio equipment due in particular to the
possibility of radio frequency (RF) interference. Please follow the safety advice given below carefully.
•
•
Switch OFF your MVPGSM in hospitals and any other place where medical equipment may be in use.
Respect restrictions on the use of radio equipment in fuel depots, chemical plants or where blasting
operations are in progress.
•
There may be a hazard associated with the operation of your MVPGSM close to inadequately protected
personal medical devices such as hearing aids and pacemakers. Consult the manufacturers of the
medical device to determine if it is adequately protected.
Operation of your MVPGSM close to other electronic equipment may also cause interference if the equipment is
inadequately protected. Observe any warning signs and manufacturers’ recommendations.

Chapter 2: Installation & Activation
GSM Instructions
Step 1 – Activate Your Wireless Account
Select a wireless network provider and follow their directions to activate your account and receive your SIM
cards.
Phone Numbers
Every channel will have its own unique phone number. The phone number may simply be given to you
by your wireless service provider or it may be on the SIM card or both. Wireless provider
implementations may vary.
Step 2 – Installing the SIM Cards
The MVPGSM requires the power supply connection to begin operation. It also requires a SIM card (Subscriber
Identity Module) to operate on a GSM network. To install the modem, do the following:
1. Turn the unit off and disconnect the power cord. Remove the three highlighted screws from the back as
shown below.
2. Slide the cover forward and up to remove it.
3. Insert the SIM cards into the units at the front of the MVPGSM.
4. Verify that the SIM cards fit into their holders properly and then replace the cover. Attach the power cord.
Step 3 – Check Signal Strength
Turn the unit on and verify that the Power LED is lit and that the Boot sequence is finished (Boot LED is no
longer active), then wait for the Link Status (LS) LED to show that the MVPGSM channel is registered on the
wireless network (flashing 75 ms on and 3 seconds off). Once registered, the Signal Strength LEDs should be
referenced for the strength of signal in its current location.
Caution: Before final placement or mounting, ensure that the wireless signal strength is strong enough for the
chosen area. If no LEDs are lit, there is insufficient signal strength for proper operation. If one or
more are lit, then there is good signal strength and operation will not be impaired. Finding a location
with the strongest signal strength is desirable.

Before final placement or mounting, ensure that the wireless signal strength is strong enough for the chosen
area. Once the unit has established connection to the wireless network, the Link Status LED will blink (75 ms on
and 3 seconds off), then you can look to the signal indicators. To find your signal strength, look at the LED
indicators on the front panel. If the first indicator is lit (“one bar”), there is sufficient signal strength for proper
operation. If two or three are lit (two or three “bars”), then there is good signal strength and operation will not
be impaired.

Chapter 4 – Configuring Your MultiVOIP GSM
Introduction
There are two methods of configuring your MultiVOIP GSM; one is through a web interface, and the other is
through the Windows software interface. There are several necessary parameters that must be set for the
MultiVOIP GSM unit to operate properly, with some additional settings that are optional. You must know the IP
address that will be used, the IP mask, the Gateway IP, and the Domain Name Server information. The
MultiVOIP GSM must be configured locally at first, but changes to this initial configuration can be done locally or
remotely. Local configuration is done through a connection between the “Console” port of the MultiVOIP GSM
and the COM port of the computer; the MultiVOIP GSM configuration software is used for this.
This chapter will explain the setup portion of the software pertaining to the list below, while Chapter 5 will cover
the Phone Book setup and Chapter 6 will discuss the Statistics options and overall maintenance of the MultiVOIP
GSM.

Chapter 4: Configuring your MVPGSM
How to Navigate Through the Software
The MultiVOIP GSM software is launched from the Start button and is found in the All Programs area under the
title of MultiVOIP GSM x.xx (where x represents version number). The top option is “Configuration” – choose
this.
Within the software, there are several ways to arrive at the parameter that you want to use: through the left-
hand panel, from the drop-down menu, clicking a taskbar icon (if available) or a keyboard shortcut (if available).
Once the initial settings are entered, you may choose to configure the MultiVOIP GSM through a Web browser
instead.
Web Browser Interface
The MultiVOIP GSM web browser interface gives access to the same commands and configuration parameters as
are available in the MultiVOIP GSM Windows interface except for logging functions. When using the web
browser interface, logging can be done by email (the SMTP option).
Set up the Web Browser interface (Optional). After an IP address for the MultiVOIP GSM unit has been
established, you can choose to configure the unit by using the MultiVOIP GSM web browser interface. If you
want to do configuration work using the web browser interface, you must first set it up:
•
Set IP address of MultiVOIP GSM unit using the MultiVOIP GSM Configuration program (the Windows
interface). The default IP address is 192.168.3.143.

Type II, SNAP
A draft standard of the IEEE about data traffic prioritization on Ethernet networks. The 802.1p
draft is an extension of the 802.1D bridging standard. 802.1D determines how prioritization
will operate within a MAC-layer bridge for any kind of media. The 802.1Q draft for virtual
local-area-networks (VLANs) addresses the issue of prioritization for Ethernet networks in
particular.
802.1p enacts this Quality-of-Service feature using 3 bits. This 3-bit code allows data switches
to reorder packets based on priority level. The descriptors for the 8 priority levels are given
below.
802.1p PRIORITY LEVELS:
LOWEST PRIORITY
1 – Background: Bulk transfers and other activities permitted on the network, but should not
affect the use of network by other users and applications.
2 – Spare: An unused (spare) value of the user priority.
0 – Best Effort (default): Normal priority for ordinary LAN traffic.
3 – Excellent Effort: The best effort type of service that an information services organization
would deliver to its most important customers.
4 – Controlled Load: Important business applications subject to some form of “Admission
Control”, such as preplanning of Network requirement, characterized by bandwidth
reservation per flow.
5 – Video: Traffic characterized by delay < 100 ms.

Coder Parameters
Coder
Manual or
Automatic
Determines whether selection of coder is manual or automatic.
When Automatic is selected, the local and remote voice
channels will negotiate the voice coder to be used by selecting
the highest bandwidth coder supported by both sides without
exceeding the Max Bandwidth setting. G.723, G.729, or G.711
are negotiated.
Selected Coder
G.711 a/u law 64 kbps;
G.726, @ 16/24/32/40 kbps;
G.727, @ nine bps rates;
Select from a range of coders with specific bandwidths. The
higher the bps rate, the more bandwidth is used. The channel
that you are calling must have the same voice coder selected.
G.723.1 @ 5.3 kbps, 6.3 kbps; Default = G.723.1 @ 6.3 kbps. Here 64K of digital voice is
G.729, 8kbps;
Net Coder @
6.4, 7.2, 8, 8.8, 9.6 kbps
compressed to 6.3K, allowing several simultaneous
conversations over the same bandwidth that would otherwise
carry only one.
To make selections from the Selected Coder drop-down list, the
Manual option must be enabled.
Selected Coder
additional
choices
G.711, G.729
-or-
G.729, G.711
Coder Priority has two options (G.711,G.729 or G.729, G711) on
the Selected Coder listing of the Coder group on the Voice/Fax
screen. If G.711 is the higher priority, i.e., G.711 is preferred to
G729 on the sending side, then G.711, G.729 option is selected.
Similarly, if G.729 has the higher priority, then G.729, G.711
option is selected.
It is used whenever a user wants to advertise both G.711 and
G.729 coders with higher preference to a particular coder.
It is useful when the calls are made from a particular channel on
the VOIP to two different destinations where one supports
G.711 and the other supports G.729.
Max bandwidth
(coder)
11 – 128 kbps
This drop-down list enables you to select the maximum
bandwidth allowed for this channel. The Max Bandwidth drop-
down list is enabled only if the Coder is set to Automatic.
If coder is to be selected automatically (“Auto” setting), then
enter a value for maximum bandwidth.
Advanced Features
Silence
Compression
Y/N
Determines whether silence compression is enabled (checked)
for this voice channel.
With Silence Compression enabled, the MultiVOIP GSM will not
transmit voice packets when silence is detected, thereby
reducing the amount of network bandwidth that is being used
by the voice channel (default = on).
Echo

Y/N
Y/N
Determines whether echo cancellation is enabled (checked) for
this voice channel.
Echo Cancellation removes echo and improves sound quality
(default = on).
Forward Error
Correction
Determines whether forward error correction is enabled
(checked) for this voice channel.
Forward Error Correction enables some of the voice packets
that were corrupted or lost to be recovered. FEC doubles the
overhead to the total network bandwidth consumed by the
voice channel (default = Off).

AutoCall/Offhook Alert Parameters
Auto Call / Offhook
Alert
AutoCall,
The AutoCall option enables the local MultiVOIP GSM to call a remote SIP
endpoint without the user having to dial a Phone Directory Database
number. As soon as you access the local MultiVOIP GSM voice/fax channel,
the MultiVOIP GSM immediately connects to the SIP end point identified in
the Phone Number box of this option. This function requires an entry in the
Outgoing phonebook of the local MultiVOIP GSM.
Generate Local Dial
Tone
Y/N
--
If selected, dial tone will be generated locally while the call is connecting
between gateways. This would be useful if there is a long network delay.
Offhook Alert Timer
Phone Number
This section is grayed-out as Offhook Alert is not used.
Phone number used for Auto Call function. This phone number must
correspond to an entry in the Outbound Phonebook of the local MVPGSM.
Dynamic Jitter
Dynamic Jitter Buffer
Dynamic Jitter defines a minimum and a maximum jitter value for voice
communications. When receiving voice packets from an SIP end point,
varying delays between packets may occur due to network traffic problems.
This is called Jitter. To compensate, the MVPGSM uses a Dynamic Jitter
Buffer. The Jitter Buffer enables the MVPGSM to wait for delayed voice
packets by automatically adjusting the length of the Jitter Buffer between
configurable minimum and maximum values. An Optimization Factor
adjustment controls how quickly the length of the Jitter Buffer is increased
when jitter increases on the network. The length of the jitter buffer directly
affects the voice delay between MultiVOIP GSM gateways.
Minimum Jitter Value
60 - 400ms The minimum dynamic jitter buffer of 60 milliseconds is the minimum delay
that would be acceptable over a low jitter network. Default = 150 ms
Maximum Jitter Value 60 - 400ms The maximum dynamic jitter buffer of 400 milliseconds is the maximum
delay tolerable over a high jitter network. Default = 300 ms
Optimization Factor
0 - 12
The Optimization Factor determines how quickly the length of the Dynamic
Jitter Buffer is changed based on actual jitter encountered on the network.
Selecting the minimum value of 0 means low voice delay is desired, but
increases the possibility of jitter-induced voice quality problems. Selecting
the maximum value of 12 means highest voice quality under jitter conditions
is desired at the cost of increased voice delay. Default = 7.
Auto Disconnect
Automatic
--
The Automatic Disconnection group provides four options which can be
Disconnection
used singly or in any combination.
Jitter Value
1-65535
The Jitter Value defines the average inter-arrival packet deviation before the
call is automatically disconnected. The default is 300 milliseconds. A higher
value means voice transmission will be more accepting of jitter. A lower
value is less tolerant of jitter. Inactive by default. When active, default = 300
ms. However, value must equal or exceed Dynamic Minimum Jitter Value.
Call Duration
1-65535
1-65535
Call Duration defines the maximum length of time (in seconds) that a call
remains connected before the call is automatically disconnected.
Inactive by default. When active, default = 180 sec.
Consecutive Packets
Lost
Consecutive Packets Lost defines the number of consecutive packets that
are lost after which the call is automatically disconnected.
Inactive by default. When active, default = 30
Network
Disconnection
1 to 65535 Specifies how long to wait before disconnecting the call when IP network
connectivity with the remote site has been lost. Default = 30 sec

MultiVOIP GSM as Email Sender. When SMTP is used, the MultiVOIP GSM will actually be given its own email
account (with Login Name and Password) on some mail server connected to the IP network. Using this account,
the MultiVOIP GSM will then send out email messages containing log report information. The “Recipient” of the
log report email is ordinarily the VOIP administrator. Because the MultiVOIP GSM cannot receive email, a
“Reply-To” address must also be set up. Ordinarily, the “Reply-To” address is that of a technician who has
access to the mail server or MultiVOIP GSM or both, and the VOIP administrator might also be designated as the
“Reply-To” party. The main function of the Reply-To address is to receive error or failure messages regarding
the emailed reports.

Supplementary Services
Supplementary Services features derive from the H.450 standard, - even though the H.450 standard refers only
to H.323, Supplementary Services are still applicable to the SIP VOIP protocols.
Of the features implemented under Supplementary Services, three are very closely related: Call Transfer, Call
Hold, and Call Waiting.
Call Transfer. Call Transfer allows one party to re-connect the party with whom they have been speaking to a
third party. The first party is disconnected when the third party becomes connected. Feature is used by a
programmable phone keypad sequence (for example, #*1).
Call Hold. Call Hold allows one party to maintain an idle (non-talking) connection with another party while
receiving another call (Call Waiting), while initiating another call (Call Transfer), or while performing some other
call management function. Feature is used by a programmable phone keypad sequence (for example, #*2).
Call Waiting. Call Waiting notifies an engaged caller of an incoming call and allows them to receive a call from a
third party while the party with whom they have been speaking is put on hold. Feature is used by a
programmable phone keypad sequence (for example, #*3).
Note that Supplementary Services parameters are applied on a channel-by-channel basis. However, once you
have established a set of supplementary parameters for a particular channel, you can apply this entire set of
parameters to another channel by using the Copy Channel button and its dialog box - to copy a set of
Supplementary Services parameters to all channels, select “Copy to All” and click Copy.

Chapter 5 – Phone Book Configuration
Introduction
The wireless connectivity of the MVPGSM provides the cost-savings of wireless-to-wireless connections and
inexpensive long distance to an existing location. By flagging calls that would connect to a remote site with
another MultiVOIP unit or calls that are to be long distance, the MVP GSM can save money by routing those calls
through the wireless connection instead of the standard PSTN. By configuring the phone books and setting up
these routes, you can ensure that the calls placed are using the least cost possible to connect. The phone books
also provide some security by limiting what numbers may be routed through them.
The “Inbound” phonebook is created with the dialing rules required for a call to be received on that VOIP. The
“Outbound” phonebook describes dialing rules used to send calls from this VOIP, over IP, to a SIP end point.
Briefly stated, the MVPGSM’s Outbound phone book lists the phone numbers it will call; its Inbound phone book
describes the dialing sequences that can be used to call in and how those calls will be directed. The phone
numbers are not literally “listed” individually, but are, instead, described by rule, such as an area code or
beginning digit.
Below you will find some basic configurations and the accompanying phone book setups to aid in the
understanding of how the phone books work. These are not necessarily the situations where your MVPGSM
would be used, but do serve to illustrate the functionality of the phone books.
Here is a basic setup example of how the MVPGSM can be put to use:

Sample Configurations

¾ MVPGSM as a Stand Alone Unit
¾ Analog VOIP and MVPGSM
¾ Load Balancing
General Notes
Suppose you want to call a phone number outside of your building using a phone station that is an extension
from your PBX system (if present). What digits must you dial? Often a “9” must be dialed to “get an outside line”
through the PBX (i.e., to connect to the PSTN). Generally, “1 “or “11” or “0” must be dialed as a prefix for calls
outside of the calling code area (long-distance calls, national calls, or international calls). For PBX units that have
a trunk access code, it’s important to enter the trunk access code (often a “9”) in the “Remove Prefix” field in
the Outbound Phonebook.
MVPGSM-to-MVPGSM
The basic setup would consist simply of two VOIPs able to communicate via IP address, with preset phone
numbers entered into the Phone Book of each unit, with the Inbound Phone Book of one unit containing the
exact same information as the Outbound Phone Book of the other unit and vice-versa. This is the underlying
concept behind the Phone Books – they are the reverse of each other so that they match information to
accomplish the connections. This is more applicable to analog VOIP units than the wireless, but it helps with
understanding the purpose of the Phone Book sections.
Example 1: The Local VOIP has channel 1 populated with a SIM using the phone number 612-555-1234 and the
Remote VOIP has 763-555-4321 as the phone number for the SIM on channel 1. By populating the
Phone Book of each unit with the information from the other, calls can be changed as to appear
local to the receiving unit. This is the most basic setup and illustrates the concept behind the Phone
Book entries and standard VOIP operation. This direct connection then takes advantage of the
wireless connection and the calls are not charged as long-distance.
Example 2: Multi-Tech VOIP units can also be set to Auto Call, in which case, either or both sides can be set to
automatically dial the other VOIP (‘612-555-1234’ or ‘763-555-4321’) when a phone number
matches the entry set to Auto Call, the MVPGSM will automatically dial the corresponding phone
number of the other VOIP unit.
MVPGSM as a Standalone Unit
Operating as a standalone unit (that is, with no corresponding VOIP unit on the receiving end), the MVPGSM can
be used as a SIP gateway to handle all long distance calls and any other call that would be less expensive if the
connection is wireless. In this case, the phone system call control module (e.g. an IP PBX) would determine the
nature of the call being placed and route it to the proper gateway. Incoming calls would be automatically routed
to the voice mail system that would then provide options for the caller to select from, e.g. a voice menu system
that informs the caller to press “0” for the operator or simply enter the digits of the extension they wish to
reach.

Chapter 5: Phonebook Configuration
Example 3: Your company has an IP PBX system with an analog VOIP unit for local calls and direct calls to the
office in another city and an MVPGSM that will handle all long distance calls. With this setup, a call
control module handles the call routing – when an extension requests an outside line (by dialing a
“9” first, for example) the call control module then watches what the first digit after the 9 is. If that
first digit is anything other than one of the local area codes, the call is routed through the MVPGSM
to take advantage of the cost savings provided by the wireless network. If the first digit is a local call,
it is sent through the standard PSTN. The analog VOIP could also be setup to connect with a remote
office VOIP as well. In this case then, there would be another access digit (an “8” for example) to
have an extension use the analog VOIP and connect to the remote location as if it were a local call.
Analog VOIP and MVPGSM
The Any Number setup entails determining a series of numbers that the VOIP unit will recognize as needing to
be routed to the remote VOIP.
Example 4: An analog VOIP and an MVPGSM are connected to the same network. Calls that are local or on the
PBX are routed by the analog VOIP, while calls that are dialed out of the local area are sent to the
MVPGSM to use the wireless network and save money. In this case, the MVPGSM is the SIP gateway
to the wireless network. Incoming calls to the MVPGSM from an external source will receive the
auto attendant and from this, external calls can access the extensions attached to the analog VOIP.
Load Balancing
The MVPGSM uses round robin load balancing to ensure that one or more SIMs are not used excessively while
others go largely ignored during times of light traffic. When Hunting is enabled, load balancing is done
automatically.
Example 5: Your MVPGSM has both channels populated with Pay-as-you-go SIM cards. You do not want the
Channel 1 SIM to carry the majority of the traffic while channel 2 sits idle waiting for channel 1 to be
busy so that it is used.
Example Inbound Phone Books
The basic purpose of the Inbound Phone Book is to create rules for routing incoming IP calls. Below you will find
the Inbound Phone Book settings for the examples that were detailed in the sample Phone Book Configurations
above.
Example 1: Local VOIP has 763-555-4321 in the Inbound Phone Book while the Remote VOIP has 612-555-1234
in the Inbound Phone Book. A user at the Local VOIP can dial 612-555-1234 and it will ring the
Remote VOIP, a user at the Remote VOIP can dial 763-555-4321 and it will ring the Local VOIP. Both
calls are treated as local area code calls.
Example 2: Local VOIP has 763-555-4321 in the Inbound Phone Book while the Remote VOIP has 612-555-1234
in the Inbound Phone Book. A user at the Local analog VOIP can pick up an attached phone and it
will ring the Remote GSM VOIP. The call is treated as a local area code call. The Auto-Call feature is
set in the Voice Parameters section.
Example 3: The Inbound Phone Book for this setup will be set to Any Number for all channels, allowing all digits
and relying on the call control module to handle the routing.
Example 4: The outbound number on the analog side matches the inbound number on the MVPGSM. The
Inbound Phone Book of the analog VOIP will list the phone number of the MVPGSM.
Example 5: Your Inbound phone book will have one entry that has “Hunting” selected for the ‘Channel Number’
selection box. The other fields will be populated per your setup, but the ‘Any Number’ selection is
used in this example to allow any call, all other entries here must have ‘Hunting’ enabled as well to
use the load balancing feature.

Chapter 5: Phonebook Configuration
Example Outbound Phone Books
The Outbound Phone Book is the director of where calls will be routed – whether that is to a specific phone
number (Any Number) or to the IP address of a remote VOIP unit for resending as a local call or out to the
wireless network to take advantage of wireless plan savings. Below you will find the Outbound Phone Book
settings for the examples that were detailed in the sample Phone Book Configurations above.
Example 1: Local VOIP has 612-555-1234 in the Outbound Phone Book while the Remote VOIP has 763-555-4321
in the Outbound Phone Book a. A user at the Local VOIP can pick up an attached phone and dial 763-
555-4321 and it will ring the Remote VOIP, a user at the Remote VOIP can pick up an attached line
and dial 612-555-1234 and it will ring the Local VOIP. Both calls are treated as local area code calls.
Example 2: Local VOIP has 612-555-1234 in the Outbound Phone Book while the Remote VOIP has 763-555-4321
in the Outbound Phone Book a. A user at the Local VOIP can pick up an attached phone and it will
ring the Remote VOIP, a user at the Remote VOIP can pick up an attached line and it will ring the
Local VOIP. Both calls are treated as local area code calls.
The Auto-Call feature is set in the Voice Parameters section.
Example 3: The Outbound Phone Book is set to the destination pattern number of the auto attendant. In this
example the MVPGSM would also be setup to use a proxy (the call control module).
Example 4: The Outbound Phone Book of the MVPGSM will have the phone number of the analog VOIP routed
to the IP address of the analog VOIP. The Outbound Phone Book of the analog VOIP will have the
phone number of the MVPGSM.
Example 5: The Outbound phone book in this example is simply going to be set at ‘Any Number’ as well – the
purpose is to have load balancing occur between the channels and allow all traffic to pass through
the MVPGSM in a round robin manner to avoid the channel one SIM using more minutes than the
other channel SIMs.

Clicking on the Advanced button brings up the Alternate Routing secondary screen. This feature provides an
alternate path for calls if the primary IP network cannot or does not respond within the timeframe of the Round
Trip Delay. Often in cases of failure, call traffic is temporarily diverted into the PSTN. However, this feature could
also be used to divert traffic to a redundant (backup) unit in case one SIP end point fails. The user must specify
the IP address of the alternate route for each destination pattern entry in the Outbound Phonebook.

The Round Trip Delay is the criterion for judging when a data pathway is
considered blocked. When the delay exceeds the threshold specified here, the
milliseconds data stream will be diverted to the alternate destination specified as the
Alternate IP Address.
The Alternate Routing function facilitates PSTN Failover protection, that is, it allows you to re-route VOIP calls
automatically if the VOIP system fails. The MultiVOIP GSM can be programmed to respond to excessive delays in
the transmission of voice packets, which the MultiVOIP GSM interprets as a failure of the IP network. Upon
detecting an excessive delay in transmission of voice packets (overly high “latency” in the network) the
MultiVOIP GSM diverts the call to another of its channels, allowing the call to go back out to the wireless
network to reach the remote end using a land line.

Authorized User Name and Password for SIP
To enable the Registration Options on the Add/Edit Inbound Phone Book, you have to activate Use SIP
Proxy Option on the Call Signaling, SIP Parameters Screen. Then add the IP address for the Primary Proxy
in the SIP Proxy Parameters. This allows you to add a Username and Password to the Inbound Phone
Book entry.
This feature is used when the MultiVOIP GSM registers with the proxies that support authorization and
need the username, password and the endpoint name to be unique.
The VOIP sends Register request to Registrar for each entry with its configured Username and Password.
When Authentication is enabled for the endpoint, then the registrar/proxy sends “401
Unauthorized/407 Proxy Authentication Required” response when it receives a REGISTER/INVITE
request. Now, the endpoint has to send the authentication details in the Authorization header. In this
header one of the fields is “username”.
Generally proxies accept requests even if both Endpoint Name and Username are same. But some
proxies expect that the Endpoint Name and Username should be different.
To support these proxies, we have the username and password configuration for every inbound phone
book entry which gets registered with a proxy.
If the username and password are not configured in the inbound phone book, then the registration will
happen with the default username and password that are configured in the SIP Call Signaling Page.
Phone Book Save and Reboot
When your Outbound and Inbound Phonebook entries are completed, click on Save Setup in the sidebar menu
to save your configuration. You can change your configuration at any time as needed for your system.
Remember that the initial MultiVOIP GSM setup must be done locally using the MultiVOIP GSM program. After
the initial configuration is complete, all of the MultiVOIP GSM units in the VOIP system can be configured, re-
configured, and updated from one location using the MultiVOIP GSM web interface software program or the
MultiVOIP GSM program.

IP Statistics
IP statistics screen
UDP versus TCP. (User Datagram Protocol versus Transmission Control Protocol). UDP provides unguaranteed,
connectionless transmission of data across an IP network. By contrast, TCP provides reliable, connection-
oriented transmission of data.
Both TCP and UDP split data into packets called “datagrams.” However, TCP includes extra headers in the
datagram to enable retransmission of lost packets and reassembly of packets into their correct order if they
arrive out of order. UDP does not provide this. Lost UDP packets are irretrievable; that is, out-of-order UDP
packets cannot be reconstituted in their proper order.
Despite these obvious disadvantages, UDP packets can be transmitted much faster than TCP packets -- as much
as three times faster. In certain applications, like audio and video data transmission, the need for high speed
outweighs the need for verified data integrity. Sound or pictures often remain intelligible despite a certain
amount of lost or disordered data packets (which comes through as static).

“Downloading” here refers to transferring program files from the PC to the nonvolatile “flash” memory of the
MultiVOIP GSM. Such transfers are made via the PC’s serial port. This can be understood as a “download” from
the perspective of the MultiVOIP GSM unit.
When new versions of the MultiVOIP GSM software become available, they will be posted on Multi-Tech’s
website. Although transferring updated program files from the Multi-Tech website to the user’s PC can
generally be considered a download (from the perspective of the PC), this type of download cannot be initiated
from the MultiVOIP GSM software’s Program menu command set.

Chapter 6: Using the Software
FTP Server File Transfers (“Downloads”)
Multi-Tech has built an FTP server into the MultiVOIP GSM unit. Therefore, file transfers from the controller PC
to the VOIP unit can be done using an FTP client program or even using a browser (e.g., Internet Explorer,
Netscape, or Firefox, used in conjunction with Windows Explorer).
The terminology of “downloads” and “uploads” gets a bit confusing in this context. File transfers from a client to
a server are typically considered “uploads.” File transfers from a large repository of data to machines with less
data capacity are considered “downloads.” In this case, these metaphors are contradictory: the FTP server is
actually housed in the MultiVOIP GSM unit, and the controller PC, which is actually the repository of the info to
be transferred, uses an FTP client program. In this situation, we have chosen to call the transfer of files from the
PC to the VOIP “downloads.” (Be aware that some FTP client programs may use the opposite terminology, i.e.,
they may refer to the file transfer as an “upload “)
You can download firmware, default configuration parameters, and phonebook data for the MultiVOIP GSM unit
with this FTP functionality. These downloads are done over a network, not by a local serial port connection.
Consequently, VOIPs at distant locations can be updated from a central control point.
The phonebook downloading feature greatly reduces the data-entry required to establish inbound and
outbound phonebooks for the VOIP units within a system. Although each MultiVOIP GSM unit will require some
unique phonebook entries, most will be common to the entire VOIP system. After the phonebooks for the first
few VOIP units have been compiled, phonebooks for additional VOIPs become much simpler: you copy the
common material by downloading and then do data entry for the few phonebook items that are unique to that
particular VOIP unit or VOIP site.
To transfer files using the FTP server functionality in the MultiVOIP GSM, follow these directions.
1. Establish Network Connection and IP Addresses. Both the controller PC and the MultiVOIP GSM unit(s)
must be connected to the same IP network. An IP address must be assigned for each.
2. Establish User Name and Password. You must establish a user name and (optionally) a password for
contacting the VOIP over the IP network. (When connection is made via a local serial connection between
the PC and the VOIP unit, no user name is needed.)
Change password
As shown above, the user name and password can be set in the web interface as well as in the Windows
interface.

Chapter 6: Using the Software
3. Install FTP Client Program or Use Substitute. You should install an FTP client program on the controller
PC. FTP file transfers can be done using a web browser (e.g., Firefox or Internet Explorer) in conjunction
with a local Windows browser a (e.g., Windows Explorer), but this approach is somewhat clumsy (it
requires use of two application programs rather than one) and it limits downloading to only one VOIP unit
at a time. With an FTP client program, multiple VOIPs can receive FTP file transmissions in response to a
single command (the transfers may occur serially however).
Although Multi-Tech does not provide an FTP client program with the MultiVOIP GSM software or endorse
any particular FTP client program, we remind our readers that adequate FTP programs are readily
available under retail, shareware and freeware licenses. (Read and observe any End-User License
Agreement carefully.) Two examples of this are the “WSFTP” client and the “SmartFTP” client, with the
former having an essentially text-based interface and the latter having a more graphically oriented
interface, as of this writing. User preferences will vary.
4. Enable FTP Functionality. Go to the IP Parameters screen and click on the “FTP Server: Enable” box.

5. Identify Files to be Updated. Determine which files you want to update. See table below.

7. Log In. Use the User Name and password established in item #2 above. The login screens will differ
depending on whether the FTP file transfer is to be done with a web browser or with an FTP client
program (varies).
8. Use Download. Downloading can be done with a web browser or with an FTP client program.
Download with Web Browser:
• In the local Windows browser, locate the directory holding the MultiVOIP GSM program files. The
default location will be C:\Program Files \Multi-Tech Systems \MultiVOIP GSM xxxx yyyy (where x and y
represent MultiVOIP model and software version numbers).
• Right-click on the file and select Copy files from Windows Explorer.
• Change focus to the Web browser window (left-clicking on the title bar will accomplish this), then right-
click in the browser window showing the file and select Paste.
• You may be asked to confirm the overwriting of files on the MultiVOIP GSM. Do so.
• File transfer between PC and VOIP will look like a transfer within VOIP directories.

Download with FTP Client Program:
• In the local directory browser of the FTP client program, locate the directory holding the MultiVOIP GSM
program files. The default location will be C:\Program Files \Multi-Tech Systems \MultiVOIP GSM xxxx
yyyy (where x and y represent MultiVOIP GSM model numbers and software version numbers).
• In the FTP client program window, drag-and-drop files from the local browser pane to the pane for the
MultiVOIP GSM FTP server. FTP client interface operations vary. In some cases, you can choose
between immediate and queued transfer. In some cases, there may be automated capabilities to
transfer to multiple destinations with a single command.
9. Verify Transfer. The files transferred will appear in the directory of the MultiVOIP GSM. Check to insure
that the new file is in place by verifying the file size and date (this is easy if this is the first time you have
done this as it will change from a file size of ‘0’ and a date of 01/01/1980).
10. Log Out of FTP Session. Whether the file transfer was done with a web browser or with an FTP client
program, you must log out of the FTP session before opening the MultiVOIP GSM Windows interface.

Chapter 6: Using the Software
The Windows interface gives access to commands via icons and pull-down menus whereas the web interface
does not. The web interface, however, cannot perform logging in the same direct mode done in the Windows
interface. However, when the web interface is used, logging can be done by email (SMTP).
The graphic layout of the web interface is also somewhat larger-scale than that of the Windows interface. For
that reason, it’s helpful to use as large of a video monitor as possible.
The primary advantage of the web interface is remote access for control and configuration. The controller PC
and the MultiVOIP GSM unit itself must both be connected to the same IP network and their IP addresses must
be known.
In order to use the web interface, you must also install a Java application program on the controller PC. This
Java program is included on the MultiVOIP GSM product CD. Java is needed to support drop-down menus and
multiple windows in the web interface.
To install the Java program, go to the Java directory on the MultiVOIP GSM product CD. Double-click on the .EXE
file to begin the installation. Follow the instructions on the Install Shield screens.

Browser choice
When installation is complete, the Java program runs automatically in the background as a plug-in supporting
the MultiVOIP GSM web interface. No user actions are required.
After the Java program has been installed, you can access the MultiVOIP GSM using the web browser interface.
Close the MultiVOIP GSM Windows interface. Start the web browser. Enter the IP address of the MultiVOIP
GSM unit. Enter a password when prompted. (A password is needed here only if password has been set for the
local Windows interface or for the MultiVOIP GSM’s FTP Server function. See “Setting a Password -- Web
Browser interface” earlier in this chapter.) The web browser interface offers essentially the same control over
the VOIP as can be achieved using the Windows interface. As noted earlier, logging functions cannot be handled
via the web interface. And, because network communications will be slower than direct communications over a
serial PC cable, command execution will be somewhat slower over the web browser interface than with the
Windows interface.

SysLog Server Functions
Multi-Tech has built SysLog server functionality into the software of the MultiVOIP GSM units. SysLog is a de
facto standard for logging events in network communication systems.
The SysLog Server resides in the MultiVOIP GSM unit itself. To implement this functionality, you will need a
SysLog client program (sometimes referred to as a “daemon”). SysLog client programs, both paid and freeware
can be obtained from Kiwi Enterprises (search the Internet for kiwi syslog daemon), among other firms. Read the
End-User License Agreement carefully and observe license requirements. SysLog client programs essentially give
you a means of structuring console messages for convenience and ease of use.
Multi-Tech Systems does not endorse any particular SysLog client program. SysLog client programs by qualified
providers should suffice for use with MultiVOIP GSM units.
Before a SysLog client program is used, the SysLog functionality must be enabled within the MultiVOIP GSM in
the Logs menu under Configuration.
Enable SysLog
The IP Address used will be that of the MultiVOIP GSM itself.
In the Port field, entered by default, is the standard (‘well-known’) logical port, 514.
Configuring the SysLog Client Program. Configure the SysLog client program for your own needs. In various
SysLog client programs, you can define where log messages will be saved/archived, opt for interaction with an
SNMP system, set the content and format of log messages, determine disk space allocation limits for log
messages, and establish a hierarchy for the seriousness of messages (normal, alert, critical, emergency, etc.).

Well Known Port Numbers
The following description of port number assignments for Internet Protocol (IP) communication is taken from
the Internet Assigned Numbers Authority (IANA) web site (www.iana.org).
“The Well Known Ports are assigned by the IANA and on most systems can only be used by system (or root)
processes or by programs executed by privileged users. Ports are used in the TCP [RFC793] to name the ends
of logical connections which carry long term conversations. For the purpose of providing services to unknown
callers, a service contact port is defined. This list specifies the port used by the server process as its contact
port. The contact port is sometimes called the "well-known port". To the extent possible, these same port
assignments are used with the UDP [RFC768]. The range for assigned ports managed by the IANA is 0-1023.”
