CUCM 8.X with Avaya 5.2.1 Integration

[smahalingam]

Hi All,

I am trying to integrate CUCM with the Avaya PBX that is runnin on the below server and gateway.

Server :s8720

Gateway :G650.

I am not familiar with the Avaya system ,but we are trying to integrate it with CUCM 8.6 using the H323 trunk.I used the below link to setup the trunk and I am having issues with calls going from CUCM to Avaya.

http://www.cisco.com/en/US/docs/voice_ip_comm/cucme/pbx/interop/notes/technote_h323trunk_ext.pdf  (This document uses CUCM 4.X has as an example and this is what I could find in Cisco's Website)

At the same time calls from Avaya to CUCM works fine.Just wanted to know if anyone here has ran into this issue and looking for inputs to resolve it.

Thanks in advance,

Simah.

Hi,

I had the same problem presented by smahalingam. After all the adjustments suggested, the problem still persisted.

I managed to solve by changing the parameter Duplex Streaming Enabled for true (false is default).

This parameter is found at Service Parameters > Cisco CallManager Service > ClusterwideParameters.

Hi

 I have setup where avaya G450 gateway is added as H323 gateway. My calling is working fine both way but the issue is its connecting with G711 instead of G729. I checked thw codec by pressing "?" button on my cisco 7942 phone.

This is what i see on avaya gateway.
