Calling Name and Number Feature
When calling from a Cisco 7960 IP phone to a Lucent/Avaya digital phone, both phones display Calling Name and Number after the call is answered as expected.
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, displays the Called Name but does not display the Called Number. It was verified using ISDN protocol analyzer that the CallManager was not sending the Connected Number information in the connect message back to PBX.

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 3640 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 3640 and the PBX.
Layer 1 (Physical Layer)
The Lucent/Avaya Definity G3si PBX configuration screen for the DS1 trunk interface is reached using change the 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/3640 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 3640 Gateway, and a check was made to ensure that there was an audio path in both directions for each call.
The Cisco 3640 Gateway with ISDN protocol type setting of PRI-NI2 supports both protocol sides by selecting "Network/User" in the protocol side field when configuring the Gateway via CallManager.
The Lucent/Avaya Definity G3si PBX supports both "USER" and "NETWORK" protocol sides by using change ds1 a12 command.
Testing was performed by Test Engineer(s): Samir Batio and Bob Graves, February 25, 2002
In test 1:
•The PBX1 country-protocol is set to 1a (US / AT&T TR 41449/41459) to emulate the Network.
•The Cisco 3640 Gateway was configured as a PRI NI2 to emulate the User.
The results are shown in the following tables.
Table 1 Basic Calls (Enbloc Sending)
Calls Made Call Comp? Calling Number passed to final destination? Calling Name passed to final destination? Called Number passed to original side? Called Name passed to the original side?
Phone A to Phone C
Phone C to Phone A
1 CallManager is not sending "Connected Number" information in the connect message back to PBX.

In test 2:
•The PBX1 country-protocol is set to 1a (US / AT&T TR 41449/41459) to emulate the User.
•The Cisco 3640 Gateway is configured as a PRI NI2 to emulate the Network.
The test results are identical to those in Test 1.
