So, if I picture this correctly, you'll have SIP phones communicating SIP to
a local Asterisk server, which then fires the calls over IAX to your server
elsewhere, from where it heads via SIP to a PSTN gateway, then breaks out
onto the PSTN?
If bandwidth costs locally are very high, I can see this as being a viable
option. However, be careful adding the extra hops doesn't increase latency
too much. I get delays of about 26-30ms over the 1mbps/256kbps ADSL line
here. Much more than, say 70ms will start to become noticable and introduce

Is there any compelling reason to use providers in Australia? You may find
it cheaper to use a provider in the US or the Far East. However, I don't
know how the telecoms structure works in Australia - in the US you generally
don't pay for local calls, here in the UK you pay for damn near everything.
I remember a couple of years ago it was cheaper to call clients in Florida
than it was to call the folks next door.

For some clients, having a Linux/BSD box on-site might be a cost-effective
alternative to the microsoft offering. I know of at least 2 of our clients
who use their asterisk server as a samba domain server.
