Can't use dtmf_type=rfc2833 in a dial plan
Hi, I recently moved up to FS 1.2 (FreeSWITCH Version 1.2.2+git~20120911T185917Z~3fd1a57902) and since then can't seem to be able to enable RFC2833 termination in the dialplan. I receive 2833 fine from the inbound: 2012-10-15 20:53:38.311883 [DEBUG] switch_rtp.c:3797 RTP RECV DTMF 0:1200 2012-10-15 20:53:40.131884 [DEBUG] switch_rtp.c:3797 RTP RECV DTMF 1:1200 2012-10-15 20:53:40.731885 [DEBUG] switch_rtp.c:3797 RTP RECV DTMF 2:1200 2012-10-15 20:53:41.031885 [DEBUG] switch_rtp.c:3797 RTP RECV DTMF 3:1200 But on the outbound I am always receiving DTMF as SIP INFO. I have tried various combinations in the dialplan of adding dtmf_type=rfc2833 in the bridge options, and setting dtmf_type=rfc2833, export dtmf_type=rfc2833, but I always receive DTMF as SIP INFO! The fact that I am receiving SIP INFO with the correct DTMF suggests that FS is identifying the RFC2833 from the inbound, but I just can't switch the DTMF mode to 2833 at will. I don't have any dtmf_type setting on the profile. Any ideas? I have currently had to fall back to pass-rfc2833=true which is OK but I would rather FS generated them so I can play with the minimum durations.

But on the outbound I am always receiving DTMF as SIP INFO.
Is the outbound leg of the call negotiating RFC2833 support? Can you show us the SDP offer+accept for the outbound leg? Regards,
