[JDEV] Voice over IP

[Greg Boulter]

I hope I'm understanding all this properly. I have a jabber client which 
does the audio video thing and I want to include some sort of discovery 
system to find out if a contact also supports the same features.

Is it then recommended that I use this "TINS" that peter millard linked to 
at
http://www.ietf.org/internet-drafts/draft-hildebrand-xmpp-sdpng-00.txt ?? 
There are a number of capabilities I'd like to check for, the ability to 
display jpegs, play mp3 files, play swf files, have access to a camera, have 
access to a microphone, maybe a few others ....

I do have a working example of a client that can handle 
audio/video/mp3/jpeg/swf files but aside from checking to see if someone is 
using my client I need a way to tell what types of media they can handle. Is 
this "TINS" going to handle that? Or am I better off looking elsewhere like 
the "Session Description and Capability Negotiation" referred to in the TINS 
document?

Greg.
