That is patently false. 

For example:

asterisk-oh323 uses an external shared object to wrap everything in 
along with the actual shared library for asterisk,  chan_h323 implements 
everything properly in one shared library.

asterisk-oh323's configuration is not even close to any other channel 
driver configuration.  chan_h323 trys to keep the same conventions that 
already have been established in other VoIP based channel drivers.

asterisk-oh323 uses a pseudo sound card implementation to pass the raw 
audio from the Asterisk side to the Open H.323.  chan_h323 uses Asterisk 
RTP stack and avoids a ton of unneeded audio processing, hence will 
scale dramatically higher.  (Fact not opinion)

And so on.....I have about a dozen other problems with asterisk-oh323.

chan_h323 is not in any way based on asterisk-oh323, the only common 
component is the Open H.323 stack.
