Re: [reSIProcate] resiprocate SipSDP cannot parse a=AS:-1

SDP grammar definition in rfc4566 does not allow negative bandwidths.  So the parser throws and an exception.

Hi,

 

I am using reciprocate 1.0 release.

 

If there is a=AS:-1 in both audio and video, the video is discarded. If  -1 is changed to a positive number, everything works fine.

 

 

Here is the SDP:

 

 

Content-Length:   329^M

^M

v=0^M

o=09000001 123456 654321 IN IP4 203.7.148.136^M

s=A conversation^M

c=IN IP4 203.7.148.136^M

t=0 0^M

m=audio 7078 RTP/AVP 0 3 8 101^M

b=AS:-1^M

a=rtpmap:0 PCMU/8000^M

a=rtpmap:3 GSM/8000^M

a=rtpmap:8 PCMA/8000^M

a=rtpmap:101 telephone-event/8000^M

m=video 9078 RTP/AVP 98^M

b=AS:-1^M

a=rtpmap:98 H263-1998/90000^M

a=fmtp:98 CIF=1;QCIF=1^M
