[reSIProcate] resiprocate and my illegal SDP

["Shaun Dawson" <scdawson@xxxxxxxxx>]

I recently sent a message about this SDP:

v=0
o=PVG 0 0 IN IP4 189.173.77.70
s=-
c=IN IP4 189.173.77.70
a=sqn: 0
a=cdsc: 1 audio RTP/AVP 8 0 116 18 13 101
a=cpar: a=rtpmap:116 AAL2-G726-32/8000
a=cpar: a=rtpmap:101 telephone-event/8000
a=cpar: a=fmtp:101 0-15
a=cpar: a=ptime:10
a=cpar: a=ptime:20
a=cpar: a=fmtp:18 annexb=yes
t=0 0
m=audio 54098 RTP/AVP 0 101
a=rtpmap:101 telephone-event/8000
a=fmtp:101 0-15
a=ptime:20


It was pointed out to me (thanks, Scott) that this SDP is illegal
because there are session level attribute lines before the 't=' line.
In my application, however, I need to support this SDP, in spite of
the fact that it is not RFC compliant.

I'm happy to parse the SDP myself, but I can't get access to the raw
data (I see that it's stored as a HeaderFieldValue in the mContentsHfv
member of the SipMessage class, though.)  Is there any supported way
of accessing this data in its raw, unprocessed form?

thanks,
 Shaun
