[asterisk-users] Asterisk 1.6 (and 1.4) DTMF problems using RFC2833
We are experiencing intermittent DTMF problems here, with the following setup: ITSP -> PIX -> Asterisk (g729, RFC2833 for DTMF). I am running Ubuntu server 10.04, but Asterisk is compiled by us and not installed from the software repository. Essentially, DTMF works for some time, but at some point it simply stops and the point at which it stops appears to be random. Using RTP debug, I can verify that the RFC2833 DTMF is being delivered in the RTP stream, and Asterisk knows of it. Independently, wireshark confirms the same. I can't easily remove the PIX, but as the RTP is showing the DTMF I do not believe the firewall is an issue. Our ITSP is registered as a SIP provider, and we can receive calls just fine. I've attached a file containing portions of the asterisk log, the wireshark log and the dialplan. Has anyone else run into this situation?

What happens here is that the DMTF activated features, like disconnect (default *) or blind transfer (default #) stops working after a while. Agents are able to transfer or hangup a few calls and then it stops working. Doing some debugging I could see that asterisk knows (receives) the DMTF too but the features are not triggered... Anyone else has run into this? Regards, -- Ing. Miguel Molina Grupo de Tecnolog?a Millenium Phone Center
