Do any of you have a preferred codec for VOIP traffic? I guess this is another case where the answer varies depending on use case, equipment, topology, etc...

I'm trying to find an optimal codec to use for remote users telecommuting at home into an asterisk system.

If you have the bandwith (roughly 100 kbps per call), G711 should give you best call quality (and least CPU usage in case Asterisk is transcoding). Otherwise, G729 is a good choice. These two should be supported by most hard- and softphones. For more exotic codecs, check what your phones support.

I would suggest that you use g729. You will need to buy some licenses from Digium ($10 each, only need to buy enough to support expected concurrent calls). It is money well spent.
