[Asterisk-Users] Asterisk - no outband DTMF with Mediatrix
Dear List members, I have this problem with Mediatrix 24-FXS-line gateway and out-of-band DTMF. It seems not working - the RTP mode is not working and when I select INFO mode, the Mediatrix is behaving just the same as with RTP mode. Here is a bunch of logs to explain this: 1. The RTP out-of-band mode (dtmfmode=rfc2833): This is OK reply from Asterisk to Mediatrix when RTP mode selected. Seems OK ;-): [...] SIP/2.0 200 OK CSeq: 1091919829 INVITE v=0 o=root 35059 35059 IN IP4 xxx s=session c=IN IP4 xxx t=0 0 m=audio 12210 RTP/AVP 8 101 a=rtpmap:8 PCMA/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-16 [...] And then, during connection with asterisk, when we use DTMF, this shows on debug: [...] May 3 17:49:42 NOTICE[139648000]: rtp.c:418 ast_rtp_read: Unknown RTP codec 96 received May 3 17:49:42 NOTICE[139648000]: rtp.c:418 ast_rtp_read: Unknown RTP codec 96 received [...] 2.

Thanks for any help, Arek Bekiersz
