Hello,

I am back to seek some more clarifications.

Is the following sdp description ok:  (the order of attribute definitions especially)

m=audio 1234 RTP/AVP 4 0
a=rtpmap:4 G723/8000
a=rtpmap:0 PCMU/8000
a=ptime:20
a=fmtp:4 bitrate=6300

or it should be,

m=audio 1234 RTP/AVP 4 0
a=rtpmap:4 G723/8000
a=fmtp:4 bitrate=6300
a=rtpmap:0 PCMU/8000
a=ptime:20


Is the ptime definition ok?
the ptime is media specific or format specific?


Please help me in clarifying the concepts.
Any help is highly appreciated.

Regards,
-Manish S. Jalan
