Thanks for the pointers... some CLI sessions with DEBUG on and digging round the docs got it sorted. I needed to specify iLBC@30i in the codec list. Pete On 4 November 2011 16:17, Anthony Minessale <anthony.minessale@gmail.com> wrote:
not enough data, do you have iLBC in your configs and mod_ilbc loaded? you need more data like a trace "console loglevel debug" "sofia global siptrace on"

Hi
I am trying to get freeswitch to bridge 2 calls while maintaining iLBC or GSM for legA, and allowing legB to choose its own codec.
This is because legA is on a low bandwidth connection so allowing PCMA/PCMU is unwise.
This works fine on a freeswitch install where there is a Sangoma transcoding card installed, however when I try it on Freeswitch with no Transcode card, it just responds with a 488.
I read in the docs that iLBC is only transcodable at ptime=30, do you think this could be the reason the transcode is not happening. The SDP looks like this from legA:
v=0. o=- 3529404938 3529404938 IN IP4 10.15.20.104. s=pjmedia. c=IN IP4 188.39.51.2. t=0 0. m=audio 4213 RTP/AVP 104 3 98 97 99 8 0 96. a=rtcp:4001. a=rtpmap:104 iLBC/8000. a=rtpmap:3 GSM/8000. a=rtpmap:98 speex/16000. a=rtpmap:97 speex/8000. a=rtpmap:99 speex/32000. a=rtpmap:8 PCMA/8000. a=rtpmap:0 PCMU/8000. a=sendrecv. a=rtpmap:96 telephone-event/8000. a=fmtp:96 0-15.
Anyone got any ideas/pointers I can look at?
Thanks
Pete
