Hi Lina, 

to your questions: 

1) The fundamental difference is in the model these two use - as you
probably know the SIP uses the Internet model - transaction oriented
(IETF) while H.323 uses "old-style" circtuit switched thinking (ITU-T). 

2) This is implementation specific. I can say that they are vendors
whose equipment can do exactly what you write (incl. the situation when
H.323 is replaced by SIP). 

3) There's no standard, but as far as I remember there is a draft
dealing with this: draft-agrawal-sip-h323-interworking-01.txt 

Kind regards

Hello,

I have several questions relating to H.323

1) What's the fundamental difference between H.323 (including fast
setup) and SIP? I don't mean the text encoding or ANS.1 encoding. 
2) Could Media gateway controller use H.323 for session creation, and
use Megaco to communicate with media gateway?
3) Is any standard there to map H.323 with SIP?

Thanks, have a nice day

Lina
