Kamlesh,
Please provide SIP traces of both call legs for a failed call.
Your last message only included a SIP trace of the call leg from the SIP
softphone to the Asterisk server. There was no SIP trace for the call leg from
the Asterisk server to the ITSP and, as shown below, that is probably where the
answer to your problem can be found.
First, the call leg from the SIP softphone to the Asterisk server successfully
negotiated G.729 as the codec:
> [May 28 11:51:34] Found RTP audio format 18
> ...
> [May 28 11:51:34] Capabilities: us - 0x104 (ulaw|g729), peer - audio=0x100
> (g729)/video=0x0 (nothing)/text=0x0 (nothing), combined - 0x100 (g729)
However, the "call.php" AGI script then failed to create the call leg from the
Asterisk server to the ITSP:
> [May 28 11:51:34] -- Executing AGI("SIP/100-0000115f", "call.php")
> [May 28 11:51:34] -- Launched AGI Script
> /var/lib/asterisk/agi-bin/call.php

> [May 28 11:51:34] -- Couldn't call yyy.yyy.yyy.yyy/12127773456

> is 'CHANUNAVAIL'
