MultiVOIP Quick Start Guide
Introduction
Welcome to Multi-Tech's new stand-alone Voice/IP Gateways
which allow analog voice and fax communication over an IP
network. The MultiVOIP model numbers are MVP400 for the
four-channel unit and MVP800 for the eight-channel unit. Multi-
Tech’s voice/fax gateway technology allows voice/fax
communication to be transmitted with no additional expense
over your existing IP network, which has traditionally been
data-only. To access this free voice and fax communication, all
you have to do is connect your MultiVOIP to your telephone
equipment and then to your existing Internet connection. Once
configured, the MultiVOIP allows voice and fax to travel down
the same path as your traditional data communications.
The MultiVOIP 400/800 supports the H.323 standards-based
protocol enabling your MultiVOIP 400/800 to participate in real-
time conferencing with other third-party VOIP Gateways or
other endpoints that support the H.323 protocol (for example,
Microsoft Netmeeting® ). The H.323 standard defines how
endpoints make and receive calls, how endpoints negotiate a
common set of audio and data capabilities, how information is
formatted and sent over the network. This version of the
software also supports optional H.323 GateKeeper software
residing on a PC which, when enabled, maintains its own
phone book database, preregisters all users, controls the
bandwidth, and handles all conferencing issues such as
transferring of calls.

MultiVOIP Quick Start Guide
Installing Your MultiVOIP
The basic steps of installing your MultiVOIP network involve
unpacking the units, connecting the cables, and configuring
the units using the included management software (MultiVOIP
Configuration). This process results in a fully functional Voice
Over IP network. A brief description is provided below with
detailed instructions provided later.
Installing and Configuring Your MultiVOIP
The VOIP administrator must first install the MultiVOIP
software and then configure each MultiVOIP 400/800 for its
specific function. During the configuration process, it’s
important to note that the Phone Directory Database is
configured differently depending on whether or not you have
GateKeeper support on your VOIP network.
If your VOIP network supports GateKeeper software, you must
register all H.323 endpoints with the GateKeeper. The
procedure for doing this is explained in the section
“Registering with a GateKeeper Phone Directory.”
If your VOIP network does not have GateKeeper software or
the GateKeeper software is not enabled, then you must build a
proprietary phone book with a “Master” MultiVOIP 400/800 and
“Slave” MultiVOIP 400/800s. The “Master” unit includes the
assignment of a unique LAN IP address, subnet mask, and
Gateway IP address, as well as the selection of appropriate
channel interface type for each of the Voice/Fax channels.
Once all connections have been made, the VOIP administrator
configures the unit and builds the Phone Directory Database
that will reside with the Master unit.
Once configuration of the “Master” MultiVOIP 400/800 has
been completed, the administrator moves on to configure the
MultiVOIP 400/800(s) designated as “Slave” units. Again,
unique LAN IP addresses, subnet masks, and Gateway IP
addresses are assigned, and each Voice/Fax channel is
configured for the appropriate channel interface type. When

Introduction
this is done, the Phone Directory Database option is set to
Slave, and the IP address of the Master MultiVOIP 400/800 is
entered. Once all Slave units are configured, the process
moves on to the “Deploying the VOIP Network” section.
Deploying the VOIP Network
The final phase of the installation is deployment of the
network. When the remote MultiVOIP 400/800s are sent to
their remote sites, the remote site administrators need only
connect the units to their LAN and telephone equipment. A full
Phone Directory Database (supplied by the Master MultiVOIP
400/800 Proprietary Phonebook will be loaded into their units
within minutes of being connected and powered up. For
remote VOIPs that were configured with the Gatekeeper
option enabled, each MultiVOIP 400/800 will be registered with
the Gatekeeper (the Gatekeeper phonebook directory is NOT
downloaded to the remote units).
The final task of the VOIP administrator or the Gatekeeper
administrator is to develop the VOIP Dialing Directory based
on the appropriate phone directory database (the Proprietary
phonebook database or the Gatekeeper phonebook
database).

Configuring the MultiVOIP
14. The Interface group defaults to FXS (Loop Start). Select
the interface option that corresponds to the interface type
being connected to the Voice/Fax Channel 1 jack on the
back panel of the MultiVOIP 400/800.
FXS (Loop Start): If a station device such as an analog
telephone, fax machine, or KTS (Key Telephone System)
is connected to the Voice/Fax connector on the back of the
unit, FXS (Loop Start) will likely be the correct Interface.
FXS (Ground Start): If the station device uses ground
start, then choose the FXS (Ground Start) option. Refer to
the device’s user documentation.
For both FXS Loop Start and FXS Ground Start , the Ring
Count FXS window allows you to set the maximum
number of rings output on the FXS interface before
hanging up and releasing the line to another call. The
default setting is 8 rings.
Note: Zero (0) means no rings; the caller hears a busy
tone.
FXO: If you are using an analog extension from your PBX,
then choose the FXO option. Check with your in-house
phone personnel to verify the connection type.
If FXO is selected, the Dialing Options Regeneration,
Flash Hook Timer, and Ring Count groups are enabled.
Check with your local in-house phone personnel to verify
whether your local PBX dial signaling is Pulse or tone
(DTMF). Then, set the Regeneration option accordingly.
The Flash Hook Timer allows you to enter the time, in
milliseconds, for the duration of the flash hook signals
output on the FXO interface. The default setting is 600
milliseconds. The Ring Count FXO window allows you to
set the number of rings received on the FXO interface
before the MultiVOIP 400/800 answers the incoming call.
The default setting is 2 rings.
Note: Zero (0) means that the MultiVOIP 400/800 never
answers.

MultiVOIP Quick Start Guide
For FXO-to-FXO communications, you can enable a
specific type of FXO Disconnect; Current Loss, Tone
Detection, or Silence Detection. Check with your in-
house phone personnel to verify the preferred type of
disconnect to use. Enabling Tone Detection activates the
Disconnect Tone Sequence options. For Disconnect Tone
Sequence, you can select from lists either one or two
tones that will cause the line to be disconnected. The
person hanging up a call must then hit the key or keys that
will produce those tones. For Silence Detection, select
One Way or Two Way, then set the timer for the number
of seconds of silence before disconnect. The default value
of 15 seconds may be shorter than desired for your
application.
E&M: If you are connecting to an analog E&M trunk on
your PBX, then choose the E&M interface option to enable
the E&M Options group. Check with your local in-house
phone personnel to determine if the signaling is Dial Tone
or Wink and if the connection is 2-wire or 4-wire. If Wink
signaling is used, then the Wink Timer is enabled with a
default of 250 milliseconds. The range of the Wink Timer
is from 100 to 350 milliseconds. Consult with your local in-
house phone personnel for this timer setting.
Note: After configuring a given channel, you can copy that
channel’s configuration by clicking Copy. Everything on
the Interface tab will be copied to the other channel.

Configuring the MultiVOIP
16. The Voice/Fax tab displays the parameters for the voice
gain, DTMF (Dual Tone Multi-Frequency) gain, voice
coder, faxing, and advanced features such as Silence
Compression, Echo Cancellation, and Forward Error
Correction.
17. You can set the input and output voice gain so that the
volume can be increased or decreased. Input gain
modifies the level of the audio coming in to the voice
channel before it is sent over the Internet to the remote
MultiVOIP 400/800. Output gain modifies the level of the
audio being output to the device attached to the voice
channel. Make your selections from the Input and Output
lists in the Voice Gain group. The valid range is +31dB to
–31dB with a recommended default value of 0.
You can set up the DTMF gain (output level in decibels) for
the higher and lower frequency groups of the DTMF tone
pair. Make your selections from the High and Low lists in
the DTMF Gain group. When the DTMF Out of Band
check box is selected, the unit reproduces the DTMF
tones instead of passing them through.
21

MultiVOIP Quick Start Guide
Note: The DTMF gain should be changed only with the
assistance of Multi-Tech Technical Support.
18. To change the voice coder, select the channel from the
Select Channel list, then click Manual in the Coder group.
Select the new voice coder entry from the Selected Coder
list.
If you changed the voice coder, ensure that the same
voice coder is used on the voice/fax channel you are
calling. Otherwise, you will always get a busy signal.
Note: If you allow the Coder to be selected automatically,
then you need to enter the Max Bandwidth. Check with
your network administrator to determine how much
bandwidth is available.
19. The Fax group enables you to send/receive faxes on the
selected voice/fax channel. You can select the maximum
baud rate for faxes and the fax volume and enter the jitter
value in milliseconds.
When receiving fax packets from a remote MultiVOIP 400/
800, it is possible for individual packets to be delayed or
received out of order due to traffic conditions on the
network. To compensate for this effect, the MultiVOIP 400/
800 uses a Jitter Buffer. The Jitter Value enables the
MultiVOIP 400/800 to wait a user-definable period of time,
in milliseconds, for delayed or out of order fax packets.
The range of allowable Jitter Values is 0 to 400
milliseconds, with a default of 400 milliseconds.
If you do not plan to send or receive faxes on a given
voice/fax channel, you can disable faxes in the Fax group.
20. You can enable the voice/fax advanced features by
clicking (checking) the silence compression, echo
cancellation, or forward error correction options.
The Silence Compression check box defines whether
silence compression is enabled for this voice channel. If
silence compression is enabled, the MultiVOIP 400/800
22

Configuring the MultiVOIP
will not transmit voice packets when silence is detected,
thereby reducing the amount of network bandwidth that is
being used by the voice channel.
The Echo Cancellation check box defines whether echo
cancellation is enabled for this voice channel. If echo
cancellation is enabled, the MultiVOIP 400/800 will remove
echo which improves the quality of sound.
The Forward Error Correction (FEC) check box defines
whether forward error correction is enabled (checked) for
this voice channel. The FEC feature allows some of the
voice packets that were corrupted (or lost) to be
recovered. FEC adds an additional 50% overhead to the
total network bandwidth consumed by the voice channel.
Note: After configuring a given channel, you can copy that
channel’s configuration by clicking Copy. Everything on
the Voice/Fax tab will be copied to the other channel.
21. The Billing/Misc tab displays the parameters for auto call,
automatic disconnection, billing options, and dynamic jitter
buffer.

MultiVOIP Quick Start Guide
If you want to dedicate a local voice/fax channel to a
remote voice/fax channel (so you will not have to dial the
remote channel), select the Auto Call Enable check box
in the Auto Call group. Then enter the phone number of
the remote MultiVOIP 400/800 in the Phone Number box.
22. The Automatic Disconnection group provides three
options to be used singly or in combination.
The Jitter Value defines the average inter-arrival packet
deviation (in milliseconds) before the call is automatically
disconnected. Jitter is the inter-arrival packet deviation
(phase shift of digital pulses) over the transmission
medium that causes voice breakup which can be
particularly disruptive to voice communications. The
default setting is 20 milliseconds. A higher value means
that the voice transmission will be more accepting of jitter.
A lower value will be less tolerant of jitter.
Consecutive Packets Lost defines the number of
consecutive packets that are lost after which the call is
automatically disconnected. The default setting is 30.
Call Duration defines the maximum length of time (in
seconds) that a call remains connected before the call is
automatically disconnected. The default setting is 180
seconds. A call limit of three minutes may be too short for
most configurations. Therefore, you may want to increase
this default value.
23. You can set billing options for inbound and/or outbound
calls by checking them in the Billing Options group and
then entering the charge in cents per number of seconds.
24. A minimum and maximum set of values can be set for
Dynamic Jitter Buffer. When receiving voice packets
from a remote MultiVOIP 400/800, it is possible to
experience varying delays between packets due to traffic
conditions on the network. This is called Jitter. To
compensate for this effect, the MultiVOIP 400/800 uses a
24

Configuring the MultiVOIP
Dynamic Jitter Buffer. The Jitter Buffer allows the
MultiVOIP 400/800 to wait for delayed voice packets by
automatically adjusting the length of the Jitter Buffer
between allowable 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
effects the voice delay between MultiVOIP 400/800
gateways.
The Minimum Jitter Value default setting is 150
milliseconds, the Maximum Jitter Value default setting is
300 milliseconds, and the Optimization Factor default
setting is 7.
Note: After configuring a given channel, you can copy that
channel configuration to the other channel by clicking
Copy Options. Everything on the Billing/Misc tab will be
copied to the other channel.

MultiVOIP Quick Start Guide
Registering with a Gatekeeper Phone Directory
This section describes how to register H.323 endpoints
with the Gatekeeper. The H.323 Gatekeeper function
resides at a PC acting as the central point for all calls
within its zone and providing call control services to
registered endpoints. The Gatekeeper performs two
important call control functions: address translation from
LAN aliases to IP addresses, and bandwidth management
where the network manager has specified a threshold for
the number of simultaneous conferences on the LAN.
In a GateKeeper environment, you will be selecting the
GateKeeper option, entering an IP address for the
GateKeeper, and accepting the default port number. If the
GateKeeper network is servicing Fast Start, accept the
defaults in the Q.931 Parameters group. If this network
zone is primarily non-Fast Start supported, you will clear
the Use Fast Start check box.
1. Select the GateKeeper option.
2. The Use Fast Start check box is selected by default. If
the GateKeeper network employs Fast Start, leave this
selected. You may have to verify whether Fast Start is
used with the GateKeeper administrator.

MultiVOIP Quick Start Guide
Building a Proprietary Phonebook Directory
To build your proprietary MultiVOIP 400/800 Phone
Directory (in an H.323 environment without the
GateKeeper option enabled), select the Proprietary
Phonebook option, then configure the “Master” MultiVOIP
400/800 and then add the “Slave” MultiVOIP 400/800s (or
other H.323 endpoints). Configuring the “Slave” MultiVOIP
400/800 is discussed later.
The first MultiVOIP 400/800 to be configured is designated
the “Master” and contains the proprietary phonebook
database. All subsequent MultiVOIP 400/800s added to
the proprietary phonebook database are designated
“Slaves”. The master database contains the phone
numbers of all H.323 endpoints available for
communication on an IP network. This database is
downloaded to each Slave MultiVOIP 400/800 as it comes
online.
To configure the “Master” MultiVOIP 400/800, verify that
the Proprietary Phonebook and Master options are
enabled. The Master IP Address, Send Status Report to
Master, and RAS Parameters group will be unavailable.

Configuring the MultiVOIP
FXS (Loop Start): If a station device such as an analog
telephone, fax machine, or KTS (Key Telephone System)
is connected to the Voice/Fax connector on the back of the
unit, FXS (Loop Start) will likely be the correct Interface
option.
FXS (Ground Start): If the station device uses ground
start, then choose the FXS (Ground Start) option. Refer to
the device’s user documentation.
For both FXS Loop Start and FXS Ground Start , the Ring
Count FXS window allows you to set the maximum
number of rings before hanging up and releasing the line
to another call. The default setting is 8 counts.
Note: Zero (0) means no rings - caller hears a busy tone.
FXO: If you are using an analog extension from your PBX,
then choose the FXO option. Check with your in-house
phone personnel to verify the connection type.
If FXO is selected, the Dialing Options Regeneration,
Flash Hook Timer, and Ring Count groups are enabled.
Check with your local in-house phone personnel to verify
whether your local PBX dial signaling is Pulse or DTMF
(tone). Then, set the Regeneration option accordingly. The
Flash Hook Timer allows you to enter the time, in
milliseconds, for the duration of the flash hook signal
output on the FXO interface. The default setting is 600
milliseconds. The Ring Count FXO window allows you to
set the number of rings received on the FXO interface
before the MultiVOIP 400/800 answers the incoming call.
The default setting is 2 counts.
Note: Zero (0) means that the MultiVOIP 400/800 never
answers.
For FXO-to-FXO communications, you can enable a
specific type of FXO Disconnect: Current Loss, Tone
Detection, or Silence Detection. Check with your in-
house phone personnel to verify the preferred type of
disconnect to use. Enabling Tone Detection activates the

Disconnect Tone Sequence options. For Disconnect Tone
Sequence, you can select from the lists either one or two
tones that will cause the line to be disconnected; the
person hanging up a call must then hit the key or keys that
will produce those tones. For Silence Detection, select
One Way or Two Way, then set the timer for the number
of seconds of silence before disconnect. Note that the
default value of 15 seconds may be shorter than desired
for your application.
E&M: If you are connecting to an analog E&M trunk on
your PBX, then choose the E&M interface option to enable
the E&M Options group. Check with your in-house phone
personnel to determine if the signaling is Dial Tone or
Wink and if the connection is 2-wire or 4-wire. If Wink
signaling is used, then the Wink Timer is enabled with a
default of 250 milliseconds. The range of the Wink Timer
is from 100 to 350 milliseconds. Consult with your in-
house phone personnel for this timer setting.
Note: After configuring a given channel, you can copy that

Configuring the MultiVOIP
9. You can set up the input and output voice gain so that the
volume can be increased or decreased. Input gain
modifies the level of the audio coming in to the voice
channel before it is sent over the Internet to the remote
MultiVOIP 400/800. Output gain modifies the level of the
audio being output to the device attached to the voice
channel. Make your selections from the Input and Output
lists in the Voice Gain group. The valid range is +31dB to
–31dB with a recommended default value of 0.
The DTMF Gain group controls the volume level of the
digital tones sent out for touchtone dialing. The selections
from the Gain High and Gain Low lists control the gain in
decibels of the high and low tones in the tone pairs. The
default gain values are -4 dB and -7 dB respectively. The
DTMF gain should be changed only with the assistance of
Multi-Tech Technical Support.
When the DTMF Out of Band check box is selected, the
MultiVOIP reproduces DTMF tones rather than passing
them from input to output.

10. To change the voice coder, the channel from the Select
Channel list, then click Manual in the Coder group. To
select the appropriate coder, select your new voice coder
entry from the Selected Coder list.
If you changed the voice coder, ensure that the same
voice coder is used on the voice/fax channel you are
calling; otherwise, you will always get a busy signal.
Note: If you allow the Coder to be selected automatically,
enter the Max Bandwidth. Check with your network
administrator to determine how much bandwidth is
available.
11. The Fax group enables you to send/receive faxes on the
selected voice/fax channel. You can set the maximum
baud rate for faxes and the fax volume in the two drop-
down lists and change the jitter value in milliseconds.
When receiving fax packets from a remote MultiVOIP 400/
800, it is possible for individual packets to be delayed or
received out of order due to traffic conditions on the
network. To compensate for this effect, the MultiVOIP 400/
800 uses a Jitter Buffer. The Jitter Value allows the
MultiVOIP 400/800 to wait a user-definable period of time,
in milliseconds, for delayed or out-of-order fax packets.
The range of allowable Jitter Values is 0 to 400
milliseconds with a default of 400 milliseconds.
If you do not plan to send or receive faxes on a given
voice/fax channel, you can disable faxes in the Fax group.
12. You can enable the voice/fax advanced features by
selecting the Silence Compression, Echo Cancellation,
or Forward Error Correction check boxes.
The Silence Compression check box defines whether
silence compression is enabled for this voice channel. If
silence compression is enabled, the MultiVOIP 400/800
will not transmit voice packets when silence is detected,
thereby reducing the amount of network bandwidth that is
being used by the voice channel.

Configuring the MultiVOIP
The Echo Cancellation check box defines whether echo
cancellation is enabled for this voice channel. If echo
cancellation is enabled, the MultiVOIP 400/800 will remove
echo-delay which improves the quality of sound.
The Forward Error Correction (FEC) check box defines
whether forward error correction is enabled for this voice
channel. The FEC feature allows some of the voice
packets that were corrupted (or lost) to be recovered. FEC
adds an additional 50% overhead to the total network
bandwidth consumed by the voice channel.
Note: After configuring a given channel, you can copy that
channel’s configuration by clicking Copy Options.
Everything on the Voice/Fax tab will be copied to the other
channel.
The Billing/Misc tab displays the parameters for auto call,
automatic disconnection, billing options and dynamic jitter

MultiVOIP Quick Start Guide
the Auto Call group. Then enter the phone number of the
remote MultiVOIP 400/800 in the Phone Number box.
14. The Automatic Disconnection group provides three
options to be used singly or in combination.
The Jitter Value defines the average inter-arrival packet
deviation (in milliseconds) before the call is automatically
disconnected. Jitter is the inter-arrival packet deviation
(phase shift of digital pulses) over the transmission
medium that causes voice breakup which can be
particularly disruptive to voice communications. The
default setting is 20 milliseconds. A higher value means
that the voice transmission will be more accepting of jitter.
A lower value will be less tolerant of jitter.
Consecutive Packets Lost defines the number of
consecutive packets that are lost after which the call is
automatically disconnected. The default setting is 30
packets.
Call Duration defines the maximum length of time (in
seconds) that a call remains connected before the call is
automatically disconnected. The default setting is 180
seconds. A call limit of three minutes may be too short for
most configurations. Therefore, you may want to increase
this default value.
15. You can set billing options for inbound and outbound calls
by selecting them in the Billing Options group and then
entering the charge in cents per number of seconds.
16. A minimum and maximum set of values can be set for
Dynamic Jitter Buffer. When receiving voice packets
from a remote MultiVOIP 400/800, it is possible to
experience varying delays between packets due to traffic
conditions on the network. This is called Jitter. To
compensate for this effect, the MultiVOIP 400/800 uses a
Dynamic Jitter Buffer. The Jitter Buffer allows the
MultiVOIP 400/800 to wait for delayed voice packets by
automatically adjusting the length of the Jitter Buffer
54
Download from Www.Somanuals.com. All Manuals Search And Download.
Configuring the MultiVOIP
between allowable 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
effects the voice delay between MultiVOIP 400/800
gateways.
The Minimum Jitter Value default setting is 150
milliseconds, the Maximum Jitter Value default setting is
300 milliseconds, and the Optimization Factor default
setting is 7.
Note: After configuring a given channel, you can copy that
channel’s configuration to the other channel by clicking

Deploying the VOIP Network
Deploying the VOIP Network
For a proprietary phone directory database, the VOIP
administrator can deploy the pre-configured slave MultiVOIP
400/800s to their remote sites. The remote site administrators
need only connect power to the pre-configured MultiVOIP 400/
800, connect the MultiVOIP 400/800 to their Ethernet LAN and
predefined telephone equipment, and then wait for the phone
directory database to be downloaded.
With the Gatekeeper option enabled on the Phone Directory
Database dialog box, all MultiVOIP 400/800s are configured
as “Master” and cannot be downloaded. In this case, each
MultiVOIP 400/800 Phone Book will be programmed with
phone numbers for its own channels. These phone numbers
are remotely registered with the H.323 Gatekeeper. See the
“Registering with a Gatekeeper Phone Directory” section for
more information.
Remote Site Administrator
The following steps are for MultiVOIP 400/800 H.323
endpoints. For non-MultiVOIP 400/800 H.323 endpoints, refer
to the appropriate installation documentation.
1. Unpack your MultiVOIP 400/800.
2. Connect one end of the power supply to a live AC outlet
and connect the other end to the Power connection on
your MultiVOIP 400/800 (See Figure 5).

3. Connect a network cable to the ETHERNET 10BASET
(RJ-45) connector on the back of your MultiVOIP 400/800.
4. If you are connecting a station device (analog telephone,
fax machine, or Key Telephone System (KTS) to your
MultiVOIP 400/800, connect the smaller end of a special
adapter cable (supplied) to the Voice/Fax Channel 1 FXS
connector on the back of the MultiVOIP 400/800 and the
other end to the station device.
If you are connecting a PBX extension to your MultiVOIP
400/800, connect the smaller end of a special adapter
cable (supplied) to the Voice/Fax Channel 1 FXO
connector on the back of the MultiVOIP 400/800 and the
other end to the PBX extension.
If you are connecting an E&M trunk from a telephone
switch to your MultiVOIP 400/800, connect one end of an
RJ-45 phone cord to the Voice/Fax Channel 1 E&M
connector on the back of the unit and the other end to the
trunk phone jack.
If you are connecting to an E&M trunk, you need to ensure
that the E&M trunk jumper is in the correct position for the
E&M type trunk. The default E&M jumper position is E&M
type 2. To change the E&M jumper position, perform the
E&M jumper block positioning procedure.

Deploying the VOIP Network
5. Repeat the above step to connect the remaining telephone
equipment to each Voice/Fax Channel on your MultiVOIP.
6. Turn on power to the MultiVOIP 400/800 by placing the
ON/OFF switch on the back panel to the ON position. Wait
for the BTG LED on the MultiVOIP 400/800 to go off
before proceeding. This may take a couple of minutes.
7. At this time your VOIP network should be fully operational.
Dial one of the sites in your network using the dialing
directory supplied by your network Administrator.
If your H.323 endpoint is not a MultiVOIP 400/800 (for
example, a PC with Netmeeting software), the Systems
Administrator for your VOIP network should do the following:
1. Make certain that the H.323 endpoint (for example, a PC
with Netmeeting, or router with voice) have been properly
connected to the network. Refer to the appropriate end
user documentation.
2. Acquire the relevant IP Addresses and/or H323 IDs (H323
IDs are required if Gatekeeper is enabled) from the other
H.323 endpoints that will participate in H.323 calls.
3. Enter the IP Addresses and MultiTech H323 IDs (H323 IDs
are required if Gatekeeper is enabled) in your phonebook
directory. You do not have to enter non-MultiTech H.323
IDs in the phonebook directory if a gatekeeper is enabled.
