Application Note Cisco 2621 Gateway-PBX Interoperability: Lucent/Avaya Definity G3si V7 PBX with Cisco CallManager Using T1 PRI NI-2 for an H.323 Gateway Introduction This document describes the interoperability of a Lucent/Avaya Definity G3si PBX connected via an ISDN T1 PRI link with a Cisco 2621 gateway. The following notes apply: Connectivity is achieved by using the industry standard PRI NI-2 protocol. The Lucent/Avaya Definity G3si can be configured as either network or user side. The Lucent/Avaya Definity G3si PBX configuration screen for the DS1 trunk interface is reached using change ds1 a12 command, setting the T1 physical layer parameters. The Cisco 2621 gateway with ISDN switch type setting of primary-ni supports both protocol sides by using the isdn protocol-emulate command. When the router is set to emulate network side and the Lucent/Avaya is set to emulate user side, the Lucent/Avaya PBX must send at least 10 digits for the gateway to properly route the call; otherwise, the Cisco 2621 gateway sends back a release message containing a release cause of Invalid Number Format. The following key features are supported: Calling/Called Number Calling Name 2003 Cisco Systems, Inc. All right reserved. Page 1 of 20 EDCS# 158623
Network Topology As shown in the following diagram, a Lucent/Avaya Definity G3si PBX is connected via an ISDN T1 PRI link to a Cisco 2621 gateway, which in turn, is connected to an Ethernet switch.
