I respectfully disagree. H323 works very well too... and when you add all  
the stuff you need to actually do telephony, you end up with things like  
SIP-T which use TCP (just like H323) and looks fairly complicated as well!

Hey, let's play devil's advocate:

The thing I like about SIP is the way it's easy to debug and trace. I  
don't like using UDP for signalisation though... with TCP, you don't risk  
loosing BYE messages and if the TCP connection is lost, you simply cut off  
the call!

Cheers,
Jean-Michel.
