When we have a call from Avaya PBX to CCM extension, on our phone, we can see only the name of other end extension but it is not showing corresponding number. As per Avaya support team, they have allowed to display Name and Number from their end. If we make a call to Avaya's Extension:, They are able to see only the number but not the name.
When there is a call between CCM and Avaya, we should be able to get both the caller ID Number and the Name.
Remote end Avaya Model: Avaya S8300 with Gateway G450 Ver. CM5.2
1. Signaling H323
2. VOIP CODECs : G.729A PT : 20ms
3. UDP port range used: From 16384 to 32767
4. Send any prefix before the extension number: NO
CallManager version 6.1
CUCM 6.1 and awaya Pbx connected via VPN
tunnel. We directly registered Awaya PBX as a h323 gateway (just like H323 router gateway).Calls are working fine from both end.
Please do reply for resolving this issue ASAP.
Thanks and regards
