Figure 1: Test Configuration
Figure 1 represents the configuration used for testing: an Lucent/Avaya Definity G3si PBX connected to a
Cisco 2621 voice gateway via an E1 PRI connection.
Set Up Notes
The Cisco 2621 Gateway with ISDN protocol type setting of primary-net5 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
change ds1 a12 command.

Caveats
•When calling from Lucent/Avaya digital phone to Cisco 7960 IP phone, IP phone displays Connected
Name and Number after the call is answered. Lucent/Avaya phone however does NOT get updated
when the call is answered. It displays the numbers being dialed instead (e.g. Access Code + extension
number). It was verified using ISDN protocol analyzer that the CallManager was not sending
"Connected Name” or “Connected Number" information in the connect message back to PBX.
•When calling from Cisco 7960 IP phone to Lucent/Avaya digital phone, Lucent/Avaya phone displays
Calling Name and Number after the call is answered as expected. Cisco 7960 phone however only
displays “Called Number” but no “Connected Name” even though Lucent/Avaya PBX was sending
both “Connected Name” and “Connected Number” IE information in the “CONNECT” message back
to 2621 Gateway.
