[asterisk-users] Help with Avaya integration

[Steven J. Douglas]

Hi David,

Thanks for your suggestion, I will give it a try at the Avaya at my 
client's place.

Here is the set up for the failed call.

Caller -> PSTN ---[Analog DID]---> Avaya ---[IP Trunk (H.323)]---> 
Asterisk ---[SIP]---> SIP Phone.

 From my packet capture on the IP Trunk of the failed call, I can see 
the following call flow.

Avaya -> SETUP -> Asterisk
Asterisk -> CALL PROCEEDING -> Avaya
Asterisk -> ALERTING + OpenLogicalChannel -> Avaya
Asterisk -> CONNECT + OpenLogicalChannel -> Avaya (this was sent when I 
picked up the call from sip phone on asterisk)

Asterisk <- RTP -> Avaya (This is where I still hear ringing from PSTN 
(via Avaya) end and modem-like sounds from the Asterisk end)

Avaya -> RELEASE COMPLETE -> Asterisk

It seems that the answer (and the resulting CONNECT) was already being 
sent to Avaya. But the Avaya did not recognize this and stop the ringing 
on the PSTN side. I'll give your suggestion a try and see if it makes a 
difference.

Thanks.

-Steve
