Thats incorrect,
a and b are both the same, 8kbps. a and b are just another way of calculating it, the result is the same and a and b are compatible. todd wrote:

Correct me if I am wrong but the way it was laid out to me was G.729 B = (5.? kbps-8 kbps) G.729 A= (8 kbps -13kbps) , these of course stats form Avaya devices, maybe for whatever reason Asterisk capable of keeping it at 8? This is way out of my area, I would love to be wrong and be able to use A if it can perform they way they want. The reason it is an issue they serve international circuits and every bit counts and adds up with the volume they do.

Is there G.729 B available for Asterisk?Does it matter? g729 has fixed-point and floating-point implementations. The data coming out the back end is the same. Either a is floating-point and b is fixed-point or the other way 'round (I can never remember). It should not make one whit of difference which one you use to generate the g729 stream. Do you have a specific reason to need one over the other? -A. _______________________________________________ Asterisk-Users mailing list Asterisk-Users@lists.digium.com http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users_______________________________________________ Asterisk-Users mailing list Asterisk-Users@lists.digium.com http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
