The chan_h323 is still horribly unstable for any type of inbound bulk calls. * 
It may or may not be stable for originating bulk h323 calls but I wouldn't 
bet on it.

I believe Jeremy is working on the issue. Until chan_h323 is fixed I would not 
rely on it for commercial operation. If you need a SIP-H323 proxy there are 
plenty available other than asterisk. If you need the extra "PBX" features of 
Asterisk, then unfortunately you have to wait..

[*] Anyone who thinks otherwise is welcome to setup a copy of Asterisk running 
chan_h323 and tell me the IP. I guarantee that I can crash it for you in 
under 5 minutes, using only inbound H323 calls
