If you're using IAX2 trunking, the bandwidth requirements will be much
less than if you're not using IAX2 trunking.  Make sure you have
trunk=yes in the peer definition in iax.conf.  Off the top of my head
(without actually running the numbers), I would guess that 30
simultaneous calls using the g.729 codec and using IAX2 trunking would
take less than 512kbit/sec in each direction.

No, just make sure you have a suitable timing source (Digium card,
ztdummy, etc.) for the IAX2 trunk.
