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..

Hope that helps..
