Summary:                    [patch] Video RTP type in response SDP not matching
the one in INVITE
Description: 
When creating the SDP for answering a SIP call only audio types are matched
against the incoming INVITE SDP. As a result the default rtp codecs type
for video are used instead.

Even if that is tenchically correct, that causes softphones like Port SIP
or Pangolin not to display incomming video as expects the same rtp codec
type for both rtp video streams.

For audio it is already done, so the it will be much more coherent to do
it in video also. The ptch is quite simple:

According to the RFC we should only answer with one or multiple codecs that
exist in the offer. I don't really understand if we break this here,
without seeing any SIP debug output.

I would like to see SIP debug output where we do wrong, and after your
patch, to be able to make a comment on what you're doing here. Thank you.
