[Freeswitch-users] m=audio 5016 RTP/AVP 96 3 107 110 0 8 101., what does it mean?

[Nathan Neulinger]

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.
