So http://www.h323plus.org is an application. Have you (or anyone) tried compiling it?
I must admit that I don't know much about this, other than my quick read of the wikipedia article. Where is the bottleneck that stops it running on the IT? The audio & video codecs presumably?
If you look here: http://en.wikipedia.org/wiki/H.323#Codecs
At least some of the audio codecs are already implemented on the DSP on the tablets. The video codecs include H.263 and H.264 which are both supposed to be implementable (is that a word?!) on the OMAP2420, probably in the IVA, for which we have no code. That's of interest to me, though these codecs can probably be implemented reasonably well on the ARM too.

Thanks for the reply! I haven't tried compiling it. I thinkopen H.323 uses H.261 for video codec..H.323plus may use H.263 for video

Nokia proclaims the tablets to support H.264 and H.263+ since OS2008. Not sure on H.263 (non +), I just recall a furious debate over whether h.264 would work with OS2007, after all, it's 263+1, right?

Yeah.. I dunno.. I've worked in the H.323 conferencing world for 10 years and was pretty surprised to see the N800 not support it out of the box... if you read the home page at http://www.h323plus.org/ you'll see why I make that whine/statement....

Ekiga ? (as a successor of gnomeMeeting, it might still have h323 ...)

Seems Ekiga should be in that list of suggested reading, too, then?
That said...I was wondering what I can do to start/offer a bounty to get a H.323 video conferencing app working for the N800 on OS2008.
These links may provide some helpful info:
