I beg to differ.  I don't think many people think SIP is not a market
success.  Compared to what?  At least from where I sit (and I sit in H.323,
SIP, MGCP/NCS, and H.248 worlds), SIP is growing at a much faster clip than
any other standard voip protocol.  IMHO, H.323 still dominates
video-conferencing (for technical reasons) and PBXes (for legacy reasons),
but SIP's adoption curve is steeper overall.  Unless you mean compared to
Skype?
