Depends on the phone.. If you are using a Grand Stream then the best you
will get is G.711 (+- 85Kb/s including overheads)..
If you are using Snom's or X-Lite/X-Pro you have the option to use the
GSM (+- 34Kb/s including overheads) codec..
X-Lite/X-Pro also support iLBC (+- 28Kb/s including overheads) although
it does not currently work with Asterisk, and GrandStream have said they
are going to support it as well soon..
All the phones have support for G.729 (+- 22Kb/s) either as standard or
by buying a sepertate licence.. Including Asterisk.
