For situations where bandwidth is limited, a codec with good compression such as G.729 is probably better, but it takes quite a bit more CPU power to transcode to/from G.729. (Of course, you could always buy a Digium TC400B transcoder card to offload the transcoding.) Another disadvantage of G.729 is that it's patent encumbered, and as such requires a license to use (again, unless you buy the TC400B card). Luckily, the licenses are quite inexpensive. -Jared -- Jared Smith Community Relations Manager Digium, Inc.
G711 is preferred if you wont face any bandwith limitation. That is why g729 is used on wan links. Voice quality should be better than g729 ans also less cpu load for asterisk.
