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.
