Since SIP is IETF not ITU its only reasonable to have internet believers
lean towards it.
H.323 ? Ahhh no thanks.
No serious look at these can even consider H.323 etc and its derivitives as
useful in the general case. The only reason they were used is the absence of
a better alternative.
Try to hook your Sony Playstation up through H.323
When would that move through committee? Spring of 2010 ??
Oh. Another reason for IETF to believe in it is that its basically a free
comm technology. H.323 wants to drag in the old timers and their costs
structures... dependance of geography, etc so there is a credible reason by
most criterea.
