[Asterisk-Users] Re: one way / irratic voice over iax and g729

[Ben Dinnerville]

The carrier does not support speex, only g729, 723 and 711, so to 
minimise codec coversions etc, and  due to the fact that licensing 723 
is so expensive and 711 is a bit fat on bandwidth (asterisk 1 is 
connecintg over 128k ISDN) we are kind of stuck with g729 (not that it 
has ever proved to be a problem anywhere else)
