I used to install PBXs and KSUs, but don't know much about VoIP, and am trying to learn.  My true background is in networking and I love phone communications.. I knew that H323 was THE protocol in VoIP, as was trying to research it, when I came across another acronym I've been hearing alot.  SIP.  It seems that SIP is a much better version H323?  do I have that right?  anyway...

I'm really trying to get my hands on a rather thorough and technical tutorial of what's involved in setting up VoIP.  I'd prefer websites, but am also open to book recommendations.  

So is H323 dead?  is SIP replacing it?  I'd like to start a general discussion about VoIP.

No H323 is still not dead, the major difference is that h323 was designed by the people dealing in telecom(ITU) so it invloves compleax message structures like Q.931 standard.On the other hand, SIP has been designed by the people who designed HTTP(IETF) so its message structure is text based like HTTP and thus simpler to implement when compared with h.323.

Few more differences are like h.323 standards costs you $$$$ whereas SIP standards are all in form of RFC's so they are free.
Both the standards are having their own merits and demerits. You can also refer to http://www.pcquest.com/content/technology/2004/104013102.asp for an introductory to differences.
