[JDEV] Voice over IP

[Joe Hildebrand]

Yes, you should look more into sdpng.

http://www.dmn.tzi.org/ietf/mmusic/sdp-ng/, and in particular:

http://www.dmn.tzi.org/ietf/mmusic/sdp-ng/drafts/draft-ietf-mmusic-sdpng-06.
txt

in order to get a better handle on TINS.  I think you can achieve all of
what you want in that framework.

By the way, I'm perfectly happy bringing this back into the JSF for work, if
that's the consensus of the group.  I just thought it might have more pull
going through the IETF.
