Chapter 1 - Introduction

About This Manual

MultiVOIP models (MVP130-AV, MVP130-AV-FXS, MVP210-AV, MVP410-AV, & MVP810-AV) being used

in systems containing Avaya PBX units and controlled by AvayaTM Communication Manager software

differ only slightly from those being used in general voice-over-IP applications. Because this is so,

comprehensive information on the general setup of these MultiVOIP units can be found in the MultiVOIP

User Guide. However, certain MultiVOIP parameters are unique to operation in Communication Manager

systems. This manual describes these parameters.

Beyond general setup information (like Mechanical Installation, & Cabling, LED definitions, and other

general info which are presented in the MultiVOIP User Guide & Quick Start Guide), this software guide

presents all the information you need to configure your MultiVOIP for use in a Communication Manager

system. It presents information on the MultiVOIP software screens as well as the related Communication

Manager screens. The MultiVOIP User Guide remains valuable as a reference source.

MultiVOIPs in Avaya Communication Manager Systems

The Communication Manager build of the MultiVOIP software allows for use of MultiVOIP units in

conjunction with IP-equipped Avaya PBX units. These PBXs are equipped with H.323 gatekeeper

functionality and support endpoints such as IP phones and MultiVOIP gateways.

In addition to functioning as a gateway, the MultiVOIP also contains an integrated gatekeeper, except

MVP130 Models. This allows the MultiVOIP to serve as it’s own alternate gatekeeper should

Communication Manager be unavailable. When serving as an alternate gatekeeper, the MultiVOIP

processes registration and call routing for it’s local FXS/FXO/DID ports as well as local Avaya IP phones.

This is the MultiVOIP’s “gatekeeper survivability” mode.

Each MultiVOIP voice channel can be registered with a primary Communication Manager gatekeeper or

one of two optional alternate gatekeepers. The optional gatekeepers can be other Communication Manager

gatekeepers or the integrated MultiVOIP gatekeeper.

The diagram below shows a common function for the MultiVOIP unit within the Communication Manager

network: the MultiVOIP allows selected callers at a site remote from the Avaya PBX units to have access to

the PBX units and all of their extensions without tolls. Voice and fax calls are supported.

Chapter 1 - Introduction

Multi-Tech Systems, Inc. Avaya Communication Manager Guide 5

Figure 1. MultiVOIP in Avaya Communication Manager System

The MVP810-AV shown in the diagram on the previous page functions as a gateway registered to one of

the Communication Managers in the IP network. The MVP810-AV provides survivable calling between the

IP Phones, stations (FXS) and trunk (FXO/DID) ports at the remote site should the WAN link go down.

The MultiVOIP will not serve as a survivable gatekeeper for IP phones on the other side of the wan link.

If the WAN link goes down, the MultiVOIP will try to register six times with the Primary Communication

Manager Gatekeeper at 3-second intervals. If the Primary gatekeeper does not respond, the MultiVOIP will

try to register with the Alternate #1 Communication Manager Gatekeeper six times at 3-second intervals. If

the alternate #1 gatekeeper does not respond, the MultiVOIP will register with the Alternate #2 gatekeeper,

which is the integrated MultiVOIP gatekeeper. If the MultiVOIP registers to its own gatekeeper, this is

gatekeeper survivability mode where the MultiVOIP will process registration and call routing for its local

FXS/FXO/DID ports as well as local Avaya IP phones.

While in gatekeeper survivability mode, the MultiVOIP checks for the availability of the primary

Communication Manager gatekeeper every 3-minutes. The MultiVOIP will re-register and discontinue its

survivability mode automatically when the primary Communication Manager gatekeeper becomes

available. Any calls that were established during the "survivable mode" which are still active while the

MultiVOIP gateway returns to "subtending mode" to the CM gatekeeper, shall be preserved by the

MultiVOIP gatekeeper. When these calls become inactive (idle), the MultiVOIP gatekeeper shall force these

endpoints to unregister with the MultiVOIP gatekeeper and re-register with the CM gatekeeper.

If the MultiVOIP is not configured as an alternate gatekeeper, and none of the Primary, Alternate #1, or

Alternate #2 CM gatekeepers respond, the MultiVOIP will enter gateway survivable mode (if enabled) and

will process calls according to it’s inbound and outbound phone books. In gateway survivable mode, the

MultiVOIP will check for the availability of the primary Communication Manager gatekeeper according to

the Switching Time Interval programmed into the Communication Manager Parameters screen of the

MultiVOIP configuration. The MultiVOIP will exit gateway survivability mode if it is able to register with

the Primary CM gatekeeper. Gateway survivability mode is enabled by checking the “Enable Survivability

Mode” checkbox in the Communication Manager Parameters screen. If IP phone survivability is required,

you must enable gatekeeper survivability mode instead by configuring the MultiVOIP as one of the

alternate #1 or alternate #2 gatekeepers.

The following Avaya IP Phone models are supported in gatekeeper survivable mode:

4601 4602 4606 4610 4612 4620 4621 4622 4624 4625

9610 9620 9630 9640 9650

Chapter 2 - Configuration

Configuring MultiVOIP for Avaya Communication Manager Use

To configure the MultiVOIP unit within such a system (similar to that in Figure 1), use the Communication

Manager Parameters screen within the MultiVOIP program. If “Register with Communication Manager

Gatekeeper” is selected, then many parameters must assume default values and those will be grayed out on

the screen. In setting up the MultiVOIP unit for Communication Manager use, bear in mind that you may

configure the MultiVOIP to operate with any combination of stations (FXS) and/or trunks (FXO/DID).

1. Configure IP Parameters

1a. Configure the IP address, gateway address, and mask used by the MultiVOIP unit in the

Configuration |IP Parameters screen of the MultiVOIP program. The IP address must match that

used in the Communication Manager “Change Node Names IP” form (dialog box).

1b. DiffServ PHB (Per Hop Behavior) values pertain to a differential prioritizing system for IP packets

as handled by DiffServ-compatible routers. There are 64 values, each with an elaborate technical

description. These descriptions are found in TCP/IP standards RFC2474, RFC2597, and, for present

purposes, in RFC3246, which describes the value 34 (34 decimal; 22 hex) for Assured Forwarding

behavior (default for Call Control PHB) and the value 46 (46 decimal; 2E hexadecimal) for

Expedited Forwarding behavior (default for Voip Media PHB).

If you wish to use just one DiffServ PHB value, Ayaya recommends the value 46 (46 decimal; 2E

hex) for both Call Control and VOIP Media.

1c. If you require that the MultiVOIP get its IP address from a DHCP server, select the “Enable DHCP”

option. The DHCP server must be located at the same site as the MultiVOIP so it is available in the

event of wan link failure. The DHCP server must issue an IP address that is statically defined on

the DHCP server so that the MultiVOIP gets the same IP address all the time.

1d. TDM Routing Option. Calls placed between ports on the same MultiVOIP voice channel board

will normally be routed over the MultiVOIP’s internal TDM (Time Division Multiplexed) bus. TDM

calls have less delay than calls routed over IP. On MVP410/810-AV models, calls between channels

1-4 or channels 5-8 will be TDM routed. Calls between voice boards (for example, channel 1 calling

channel 5) will be IP routed. If you require all calls to be IP routed, disable the “use TDM Routing

for Intra-Gateway Calls” option. This should not normally be required, so it is recommended that

you leave TDM Routing enabled.

Chapter 2 - Configuration

Multi-Tech Systems, Inc. Avaya Communication Manager Guide 7

1e. TCP/UDP port requrements. To ensure proper functioning of the MultiVOIP, the TCP/UDP

network connection must not be blocked on the network connection between the MultiVOIP and

CM.

The UDP ports used by the MultiVOIP are as follows:

Channel RTP Port RTCP Port T38 Port

1 5006 5007 5008

2 5016 5017 5018

3 5026 5027 5028

4 5036 5037 5038

5 5046 5047 5048

6 5056 5057 5058

7 5066 5067 5068

8 5076 5077 5078

The TCP ports used by the MultiVOIP are as follows:

H.225 Listen Port – User configured for each channel in the CM Settings screen (default 1721 –

1728)

H.225 Client Port – Dynamic (16000 – 20000)

H.245 Listen Port – Dynamic (16000 – 20000)

RAS Client Port – Dynamic (16000 – 20000)

1f. Emergency Transfer. Emergency transfer allows local analog telephones to access the local CO and

to answer telephone calls during a power failure.

For the various products the features operate as follows:

MVP210-AV

Port 1 is connected to Port 2

MVP410-AV

Port 1 is connected to Port 2

Port 3 is connected to Port 4

MVP810-AV

Port 1 is connected to Port 2

Port 3 is connected to Port 4

For example, suppose ports 1 and 3 of MVP410-AV are configured as FXS with telephones

attached. Ports 2 and 4 are configured as FXO trunks with CO lines attached. If there is a power

failure, the telephones on ports 1 and 3 would automatically be connected to the CO lines attached

to ports 2 and 4 allowing inbound and/or outbound call to be make.

Note: This feature shall only be available on “AV” models of the gateway that are:

Rev B: For the MVP410 and MVP810 models

Rev B: For the MVP210 model

Chapter 2 – Configuration

2. Configure Interface Parameters.

2a. Determine which voice channels will be stations (FXS), trunks (FXO/DID), or disabled. Configure

them as such in the Configuration | Interface screen of the MultiVOIP GUI.

2b. If you are configuring a DID-DPO (Direct Inward Dial – dial-pulse originating) interface for DID

incoming calls, you need to chose DID-DPO from the pull down menu for Interface Type. You also

have to set the DID Options Start Modes; Immediate Start, Wink Start, or Delay Dial.

Immediate Start allows the MultiVOIP to detect the off-hook condition at the originating end of the

call and becomes ready to receive the digits immediately.

Wink Start allows the MultiVOIP to detect the off-hook condition at the originating end of the call.

The MultiVOIP then reverses the battery polarity for a specified time (140-290 ms; a “wink”) and

then becomes ready to receive the dialed digits. You can select the Wink Timer duration (140 to 290

ms).

Delay Dial allows the MultiVOIP to detect the off-hook condition at the originating end of the call.

Then the MultVOIP reverses battery polarity for a specified time (reverse polarity duration has a

wider acceptable range than Wink Start) and then becomes ready to receive dialed digits.

2c. Enable the “Message Waiting Light” feature if you have FXS Interface selected and are using an

Avaya analog telephone with Message Waiting indicator or enable “Stutter Dial Tone” if you are

Chapter 2 - Configuration

Multi-Tech Systems, Inc. Avaya Communication Manager Guide 9

using a non-Avaya analog telephone. This station must be properly administered in the Audix

Voice Mail System for the message waiting feature to work.

2d. Activate the “Caller ID” feature if you have FXS Interface selected and are using an analog

telephone with caller ID display. The MultiVOIP will output Caller ID information, if received,

between the first and second rings.

2e. Activate “Caller ID” on FXO interfaces if the attached line supports it. The MultiVOIP will capture

the Caller ID information, if provided, between the first and second rings and will forward the

information to CM.

Note: If the CM customer is operating on CM release 2.0.1 (or newer), remember that for the ‘h323’

specified station, the following CM admin fields must be set appropriately:

a) The ‘Message Waiting’ field must be enabled and set to “led” if this feature is intended to be

supported on the MultiVOIPs analog station port.

b) Similarly, the following features must be enabled as desired:

•Switchhook flash

•Call Waiting Indication

•Attendant Call Waiting Indication

3. Configure Voice/Fax Parameters.

3a. In the MultiVOIP’s Configuration | Voice/Fax Parameters screen, configure the voice channels for a

voice coder that is supported by Communication Manager.

The voice coder selected must match the voice coders listed in the ip-codec-set for the network

region the MultiVOIP resides in. If only G.729 is listed in the ip-codec-set, select G.729 on the

MultiVOIP. If G.711 is listed before G.729 in the ip-codec-set, select G.711, G.729 on the MultiVOIP.

If G729 is listed before G.711 in the ip-codec-set, select G.729, G.711 on the MultiVOIP.

There is one exception, if only G.711 is listed in the ip-codec-set, you must select G.711, G.729 on

the MultiVOIP. This will allow support for G.711 for CM managed calls, and will allow support for

G.729 for survivable mode calls. The MultiVOIP only supports G.729 in survivable mode.

The table below shows the bandwidth required per voice channel based on the codec selected and

the CM “Frames per Packet” setting in the “Change IP-Codec-Set” screen.

Bandwidth per Channel

Voice Frames per IP Packet

Coder 1 2 3 4

G.729 40K bps 24K bps 18K bps 16K bps

G.711 96K bps 80K bps 74.7K bps 72K bps

3b. If the CM customer desires that a particular FXS port is to operate as a “hot extension”, set the

“auto call/off-hook alerting” feature to auto call and enter the desired destination number in the

“phone number” field. Enabling this feature allows an analog phone user to be able to lift his/her
