This just in. H.323 is dead.
I was reading an article that Ken Camp put up over at his excellent Realtime VoIP blog. The article,
entitled "VoIP Top 10 tips for IT
Directors" and I thought the whole thing was quite good, with one small exception:
Current VoIP
systems use either a proprietary call signalling protocol, or one of two standards, H.323 and the session initiation
protocol (SIP). Although SIP appears to be becoming the most popular, neither has won the race to be the de-facto VoIP
standard. Consequently, organizations moving to VoIP should seek out gateways and other network elements that can
support both H.323 and SIP. Such a strategy helps to ensure compatibility of your VoIP network in the years that come,
no matter which protocol dominates.
Now, I don't know about Mom and Pop's PBX Corp., but Avaya and
Cisco aren't exactly pouring money into H.323 research. No, all indications are SIP, and the standard is as good as
gold at this point. Take SIP to the bank, and don't worry about H.323 unless you already have in-house H.323
equipment under a lengthy lease. And Ken's right. This "top 10 list" only has nine items in it. Sharp
eye, Ken.
Also, since we're in the mood for tips, check this out. Eight more tips.
H.323 is DEAD

(Page 1)2. This is nonsense. H.323 is far from dead, in fact it is the workhorse of billable VoIP minutes. The real truth is SIP is not materialising as planned. And what about JINGLE?

1. Hey Ted, you're right, but big vendors of Telcos equipments are not really pushing SIP yet... My company was involved in the development of a new video service for a 3G operator and this vendor asked me to develop this service using H323, because their version of "SIP-like" video gateway didn't support DTMF tones... so, better H323 than patching their gateway. To me, this is a shame...
