6-2 Preliminary November 23, 1998 MultiVoice Gateway for the MAX— User’s Guide

Configuring MultiVoice

Configuration options

The MultiVoice call configuration options are located in the VOIP Options submenu of the

Ethernet profile:

You must provide an IP address for the GK IP Adrs parameter for the MultiVoice Gateway to

process voice calls. This address points to the computer running the MultiVoice Access

Manager that will perform all of the Gatekeeper functions for this Gateway. The MultiVoice

Gateway can process calls over must IP networks using the factory defaults for the remaining

VOIP Options parameters.

Understanding the VOIP parameters

This section provides background information about the VOIP Options parameters. (For

complete information, see the MAX reference Guide.)

The Gatekeeper IP address

The GK IP Adrs parameter identifies the computer running MultiVoice Access Manager that

will perform all the H.323 Gatekeeper functions for this Gateway. Since MultiVoice

implements the H.323 direct call model for Voice over IP networks, each Gateway must

communicate with an Gatekeeper for processing of call registration, admission and status

(RAS) messages. The MultiVoice Gateway will send all call request messages and call

processing information to the IP address specified by GK IP Adrs.

The secondary Gatekeeper IP address

The 2nd GK IP parameter identifies the computer running MultiVoice Access Manager that

will perform all the H.323 Gatekeeper functions for this Gateway, when it can’t register with

MVAM on the system identified by GK IP Adrs. This allows a MultiVoice Gateway to

continue initiating new calls over the IP network.
