[Sip-implementors] SDP Negotiation

[John Fisher]

Is there a standard method in choosing a codec when presented with several?    For instance (note the audio line):   v=0 o=mhandley 2890844526 2890842807 IN IP4 126.16.64.4 s=SDP Seminar i=A Seminar on the session description protocol u=http://www.cs.ucl.ac.uk/staff/M.Handley/sdp.03.ps [EMAIL PROTECTED] (Mark Handley) c=IN IP4 224.2.17.12/127 t=2873397496 2873404696 a=recvonly m=audio 49170 RTP/AVP 0 8 m=video 51372 RTP/AVP 31 m=application 32416 udp wb a=orient:portrait Can I start blasting this SIP client with either PCMU or PCMA packets, based on whatever I like better?   I found the following draft on the subject, but it is fairly new and I wanted to see what people have been doing until this draft came about.  http://search.ietf.org/internet-drafts/draft-andreasen-mmusic-sdp-simcap-04.txt   Thanks, John
