<br>
I am trying to get freeswitch to bridge 2 calls while maintaining iLBC<br>
or GSM for legA, and allowing legB to choose its own codec.<br>
<br>
This is because legA is on a low bandwidth connection so allowing<br>
PCMA/PCMU is unwise.<br>
<br>
This works fine on a freeswitch install where there is a Sangoma<br>
transcoding card installed, however when I try it on Freeswitch with<br>
no Transcode card, it just responds with a 488.<br>
<br>
I read in the docs that iLBC is only transcodable at ptime=30, do you<br>
think this could be the reason the transcode is not happening. The SDP<br>
looks like this from legA:<br>
<br>
v=0.<br>
o=- <a href="tel:3529404938" value="+13529404938">3529404938</a> <a href="tel:3529404938" value="+13529404938">3529404938</a> IN IP4 10.15.20.104.<br>

Anyone got any ideas/pointers I can look at?<br>
<br>
