Well, if your Asterisk server is right next to your UA (ATA-186) on
the same ethernet, you don't gain anything - you should stick with
the ~80kbps G711 codecs which sound better. If your Asterisk server
is on a different continent across a 56kbps satellite link, then I
would suggest that you look into the G729 codec. People who are
bandwidth constrained and have multiple UA's connecting from distant
locations are most likely to benefit from G729.
>Do the Cisco ATA186s have any ability to handle this codec?
Yes. Set LBRCodec to "3" and then set TXCodec to "3" and
RXCodec to
"3" to set G729

Only if you have critical bandwidth shortages.
>Also, is the license "once in a lifetime" for a given channel?
One-time payment per channel. No recurring fees.
