[OpenSIPS-Users] all sip body headers regarding video removed

[Bogdan-Andrei Iancu]

Hi Cindy,

What you describe as bug #2 is not really a bug - First of all opensips 
works at codec level - you are able to remove /change order of codecs, 
but you cannot remove streams or sessions from SDP.  So whatever info is 
associated to the sessions/streams will stay there. Secondly, opensips 
does not have the fully SDP "wisdom" to be able to remove all attributes 
related to a codec.

Regards,
Bogdan
