I can also confirm chan_h323 and g.729 work well to 5300s, but we had to build on RH8 not RH9. Haven't tried 5300 to Asterisk except via SIP which works fine--even to i4l interfaces.

I've done some reviewing of the archives for G729 and H323 experiences. The landscape of that query isn't pretty - lots of pleas for help, and nor do I see too many "answers." I have a pending bid that requires some data before I can implement * on this particular solution.


My question is perhaps a slightly differently worded one than has been asked before, but it may be the case that it is the same question as I have seen already posted (with no 'definitive' answer):

"Can g729 calls of type g729r8 or g729br8 from a Cisco AS5300 be terminated on Asterisk systems and sent out Zap interfaces?"


Yes, g729r8

If the answer is "Yes," then are there any specific patches I will need? Which of the two H323 drivers works? Both? Of course, I assume that the G729 licenses from Digium are required for each active channel.


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
