Summary:                    [patch] When SIP caller does not offer video, adding
video drops the call
Description: 
2 video capable SIP devices on the same LAN (directmedia enabled)

Caller sends an initial INVITE, but does NOT include any video, then no
video-rtp object is initialised. Video is still offered to the callee, as
they are capable of it.

If the callee then requests video, then the attempt to enable direct media
causes the call to be dropped as the SDP data gets very confused by having
video requested, but no video-rtp object at the same time.

Don't offer video to directmedia callee unless caller offered it as well

Make sure that when directmedia is enabled, that video is not offered to
the
callee even if it supports it. p->vrtp will not exist since the caller
didn't
offer video.
