Hi, Alain!
You could use the SDP transformations combine with regular expresions. I
am thinking at something like:
if ($(rb{sdp.line,m}) =~ "AVP\s*8")
xlog("PCMA is first codec!\n");
Hope this is useful :)

media line(m) shows codec preference in order.

Hi all,
Is there a way to know the order of the codecs?
For exemple in this SDP :
m=audio 13406 RTP/AVP 8 0 101
a=rtpmap:8 PCMA/8000
a=rtpmap:0 PCMU/8000
a=rtpmap:101 telephone-event/8000
How i know that the prefered codec is PCMA ?
Regards,
Alain
