Hi Did your try forcing a codec(s) by setting the absolute_codec_string var ? try something like this <action application="export" data="absolute_codec_string=G722"/> and disable late negotiation. On Tue, Oct 22, 2013 at 6:54 PM, Michael Jerris <mike@jerris.com> wrote:

Hey,
I tried to establish audio call between two clients having different codec supports . I expected that transcoding would take place. But I am getting a codec negotiation error .
Here is the information about client I am using
leg A : suppoerted codec : speex
leg B: supported codec : G722,PCMU,PCMA,GSM,OPUS
