[Asterisk-Users] Which VoIP, H.323, SIP reference books are recommended?
I can't speak to H323, but there seem to be quite a few titles out there. The one SIP book I found was the O'Reilly "Practical VOIP using VOCAL" which is fairly specific to using the Vovida (Cisco) VOCAL package, but it had a reasonable explanation of SIP. Personally, I'd suggest you start surfing the Cisco website and looking for their whitepapers on SIP - they are well-written and illustrated, and are more current than most printed material you'll be able to find. H323 supposedly is the bulk (90% was the quote I heard) of VOIP traffic on the big carrier-to-carrier networks, but I'd say that almost every vendor is trying to figure out how to convert to SIP. I'm trying to avoid learning H323 in detail until it's absolutely required, but I have a number of books here that claim to be able to tell me what I need to know (though I haven't read them, so can't recommend them.)
