[asterisk-users] Receiving musinc on hold instead of ring

[Tarek Sawah]

this is related to your carrier's SIP messages as they are sending a sendonly attribute instead of sendrecv (taking a wild guess here) your asterisk will act as if the call was placed on hold thus the MOH butts in. 
an sip debug log for a similar call will be more helpful?

> 
> Example dialplan execution:
> 
> -- Executing [0021266xxx at test:13] Progress("SIP/100-00001e04", "") in new stack
> -- Executing [0021266xxx at test:14]
> Dial("SIP/100-00001e04","SIP/21266xxx at x.x.x.x") in new stack
> -- Called 21266xxx at x.x.x.x
> -- Call on SIP/x.x.x.x-00001e05 placed on hold
> -- Started music on hold, class 'default', on SIP/100-00001e04
> -- SIP/x.x.x.x-00001e05 is making progress passing it to SIP/100-00001e04
> 
> Now, a SIP packet capture shows no trace of the call being put on hold!
> 
> Sample wireshark capture for the same call:
> 
> x.x.x.x -> y.y.y.y SIP/SDP Request: INVITE sip:21266xxx at x.x.x.x, with
> session description
> y.y.y.y -> x.x.x.x SIP Status: 100 Giving a try
> y.y.y.y -> x.x.x.x SIP/SDP Status: 180 Ringing, with session description
> 
> And I get the music on hold instead of the ringtone. I have tried
> placing Progress() in front of Dial() but to no avail. I do not want
> to use the "r" option in Dial() because then I lose the destination
> ringtone in early media which is important to my customers.
> 
> Anybody had a similar issue? Any idea of what parameters I can try to
> tweak, as I am stumped...
