I think this may be what you're looking for... http://www.iana.org/assignments/rtp-parameters/rtp-parameters.xml 96+ are dynamic apparently 0, 8 pcmu and pcma 3 is gsm At least according to that list... I don't know enough about the protocol to know how the dynamic ones are assigned. This that's odd though is that the list on that page is in decimal, with comfort noise at 13. That would make sense if it were in hex (19), so maybe I'm misinterpreting. -- Nathan On 06/22/2013 10:02 PM, Sayyed Mohammad Emami Razavi wrote:

Can any body describe this statement?!
For example in response to one of my questions, Steven told me: "Your phone is not offering any codecs in the INVITE: m=audio 15696 RTP/AVP 19 The only payload type listed is 19 (comfort noise) - there are no codecs listed." base on my logs: http://pastebin.freeswitch.org/21084
