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
