AFAIK the a= line is not mandatory at all. For example, the following case: m=audio 15996 RTP/AVP 0 8 a=rtpmap:0 PCMU/8000 a=rtpmap:8 PCMA/8000 means the same than: m=audio 15996 RTP/AVP 0 8 This is because 0 and 8 are standard codecs, but I think that values above 100 are not standard so maybe they require "a=" line (so you would be right). -- Iñaki Baz Castillo <[email protected]> _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
