[SIPForum-discussion] Ordering of rtpmap attribues in SDP

[Rajangam.Subramanian at alcatel.com]

Hello all,
    I have a query related to the SDP parameters in the SIP message.
The following is the SDP info that is received in the INVITE message.

m=audio 7143 RTP/AVP 8 98
a=sendrecv
a=rtpmap:98 amr/8000

  The a=sendrecv attribute is before the rtpmap description of the Codec 
98. Is it acceptable to receive a SDP in this format? What should the 
receiver of such an SDP do accept it and process or reject it??

I searched in RFC2327 but there are no specific information given about 
the ordering.

Regards,
jango
