Don't use g729 unless you really need it. Even on an old ADSL-1 connection in the UK (256Kbps upstream), you can run 2 G711 calls over IAX (b/w needed on an IAX trunk for 2 calls is 80+65 = 145Kb/sec each way. (give or take) Even 2 SIP calls @ 160Kbps ought to be fine. However I've transcoded over 10 concurrent g729 calls on a 1GHz VIA processor, so it's possible if you really need to do it.
