I was wondering if anybody knew of a Jabber client that supported H.323 calls. I'm trying to integrate our current Tandberg VTC system with our new Jabber do-everything-you-could-possibly-dream-of system, with the eventual goal of phasing out the ridiculously overpriced Tandberg units, but my command group won't give me full support unless I find a way to make the jabber client backwards compatible with our Tandbergs.  I've already looked at neos mt, but I don't see a way to make h.323 calls to specific IP addresses on the LAN, plus the constant disconnect is extremely annoying.  Any ideas?
