This application note discusses the integration of the Lucent/Avaya Definity G3si V9 PBX with CallManager using the Cisco 2621-T1 PRI NI-2 Gateway.

Integration Description

Connectivity is achieved by using the industry standard PRI NI-2 protocol. The Lucent/Avaya Definity G3si can be configured as either the NETWORK or USER side. The figure below shows the general network layout for the integration.

Considerations

User/Network Settings

The Cisco 2621 router with an ISDN switch type setting of primary-ni supports both protocol sides using the isdn protocol-emulate network/user command. When the router is set to emulate the Network side and the Lucent/Avaya is set to emulate the User side, the Lucent/Avaya PBX must send at least 10 digits for the router to properly route the call. Otherwise, the Cisco 2621 router sends back a release message containing a release cause of "Invalid Number Format."

Calling Name and Number Feature

When calling from a Cisco 7960 IP phone to a Lucent/Avaya digital phone, the Lucent/Avaya phone displays the Calling Name and Number after the call is answered as expected. The Cisco 7960 phone, however, displays only the Called Number but not the Connected Name, even though Lucent/Avaya PBX is sending both the Connected Name and the Connected Number IE information in the CONNECT message back to the Cisco 2621 Gateway.

When calling from a Lucent/Avaya digital phone to a Cisco 7960 IP phone, the IP phone displays the Connected Name and Number after the call is answered. The Lucent/Avaya phone, however, does not display the Called Name or Called Number. It displays the trunk name instead. It was verified using an ISDN protocol analyzer that the CallManager was not sending Connected Name or Connected Number information in the connect message back to PBX.

Integration Testing

This section contains information about the setup used in testing the integration of the Lucent/Avaya Definity G3si and the Cisco 2621-T1 PRI NI-2 Gateway.

Test Configuration

The following figure represents the various configurations used for testing.

Testbed Network Configuration

As shown in the figure above, a Lucent/Avaya Definity G3si PBX was connected via an ISDN T1 PRI link to a Cisco 2621 Gateway, which in turn, was connected to an Ethernet switch. The interoperability testing involved Layers 1, 2 and 3 on the ISDN PRI link between a Cisco 2621 and the PBX.

Layer 1 (Physical Layer)

The Lucent/Avaya Definity G3si PBX configuration screen for the DS1 trunk interface is reached using the change ds1 a12 command, which sets the T1 physical layer parameters.

Layers 2 & 3 (Q.921 and Q.931)

Layer 2 and 3 packet exchanges were monitored using an Acacia Clarinet protocol analyzer, bridged across the PRI link in high impedance mode.

Layer 2 Q.921 packets were monitored to ensure that each PBX/2621 software configuration properly exchanged SABME/UA packets to initialize the ISDN link, and then RR packets were exchanged every 30 seconds.

Layer 3 Q.931 packets were monitored to ensure that the appropriate call setup/teardown packets were exchanged for each configuration, and that the SETUP packets contained the mandatory Information Elements with the necessary details, as well as optional IEs such as Calling Name and Number.

Telephone calls were made end-to-end in both directions through the Cisco 2621 Gateway, and a check was made to ensure that there was an audio path in both directions for each call.

User/Network Settings

The Cisco 2621 Gateway with ISDN protocol type setting of primary-ni supports both protocol sides by using the isdn protocol-emulate network/user command.

The Lucent/Avaya Definity G3si PBX supports both "USER" and "NETWORK" protocol sides by using the change ds1 a12 command.

Test Results

Testing was performed by Test Engineer(s): Samir Batio, October 2, 2001

Test 1

In test 1:

•The PBX1 country-protocol is set to 1a (US / AT&T TR 41449/41459) to emulate the Network.

•The Cisco 2621 Gateway is configured as a PRI NI2 to emulate the User.

The results are shown in the following tables.

Test 2

In test 2:

•The PBX1 country-protocol is set to 1a (US / AT&T TR 41449/41459) to emulate the User.

•The Cisco 2621 Gateway is configured as a PRI NI2 to emulate the Network.

When the Cisco 2621 router is set to emulate Network side, the Lucent/Avaya PBX must send at least 10 digits for the router to properly route the call. Since the PBX is configured for 4 digit dialing, calls were tested in one direction only, from Cisco 7960 IP phone to Lucent/Avaya digital phone. The test results are identical to those in Test 1.
