However, I do I go about continuing the call? Currently we can only create a new call, using the URI in the Contact header of 3xx response as the destination of the call. So yes, the Call-ID will change for the new call. I don't think this is a major issue, CMIIW.

But do tell me if you absolutely need this feature, then maybe we can discuss possible solutions. cheers, -benny Thanks a bunch. > > > > > > ____________________________________________________________________________________ > Be a better friend, newshound, and > know-it-all with Yahoo!
