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:
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 WebLM licenses should be observed in order to avoid displaying inaccurate information about call handling.
Protocol
Configure the DEFINITY or MultiVantage system for IP stations, to preferably use the type 7434ND protocol.
