Description David Laban 2010-12-30 01:55:26 UTC

Technical Details:
sofiasip sends:

INVITE
...
m=video
...
m=audio
...

peer replies:

200 ok
...
m=audio
...
m=video
...

sofiasip gets confused by the re-ordering and says:

(telepathy-sofiasip:14563): tpsip-WARNING **: priv_update_remote_media: The 
peer has changed the media type, don't know what to do

then sends BYE and invalidates the channel.


I'll see if I can write a test for this today. I'll put it on top of my streamedmedia_tests branch.

RFC 3264 section 6 says:

   For each "m=" line in the offer, there MUST be a corresponding "m="
   line in the answer.

The peer is doing it wrong.
