Yes, g729r8

Others seem to have massive issues with chan_h323 and G.729, but i've 
dealt a dozen or so 5300s of which I haven't had any trouble whatsoever, 
with nothing other than the code that is currently in the cvs.  However, 
I have only terminated calls from Asterisk to the 5300, never from the 
5300 to Asterisk.

If Asterisk is going to be encoding G.729, yes you will need licenses 
from Digium.

P.S. I'm biased and cannot comment about that other driver
