Configuring DEFINITY or MultiVantage for VoIP

When configured for Voice over IP (VoIP), an Avaya DEFINITY or MultiVantage system that is enabled for Internet Protocol (IP) acts as a Gateway to the public switched telephony network (PSTN).The primary role of the switch is to convert circuit-based connections on the PSTN to and from packet-based connections that are part of an IP network with an Avaya IR system.

Requirements

Configuring a DEFINITY or MultiVantage system for VoIP requires installation of:

• The Voice over IP feature on the IR system
• The Avaya IR system must be connected to a local area network (LAN) that also supports a DEFINITY MultiVantage 1.3 with R11 system software

Configuration settings in the Avaya IR system Voice over IP screens must match those in the MultiVantage or DEFINITY IP Networking configuration screens. Additionally, limits of the VoIP RTUs should be observed in order to avoid displaying inaccurate information on call handling.

Protocol

Configure the DEFINITY or MultiVantage system for VoIP to use the H.323 Terminal (Station) protocol.
