I am no expert either. I could be very wrong but I was just under the
impression that Ekiga still did the video portion with H.323 and did
audio with SIP if requested. It is a confusing mish-mash of clients
out there and I don't know of any pure SIP client that handles video
even if SIP can handle a video stream. There seems to be a reluctance
to do everything with SIP. Even Gizmo uses SIP for voice and
Jabber/XMPP for text when text can be done with SIP/SIMPLE.

Maybe XMPP promises to unify audio/video/text but that has yet to happen.
