I see.

I have a friend who runs a hosting business in Vancouver and they have 
plenty of servers and good bandwith - and there's a telecom carrier 
called Group Telecom in the same building - and I think they can provide 
SIP trunks that terminate directly to TDM. So it'd still be your own 
server but it would be off your production site. You can get in touch 
with me off list if you want to explore this option.

I don't really like IAX... it's not a standard, has some compatibilities 
issues within itself depending on the version of Asterisk which you use, 
and doesn't separate media from signaling properly. Oh, and trunking a 
large number of channels can be hazardous too.

I think you're right: if bandwith is not a problem, SIP / G711 is the 
only sensible way to go. Otherwise, SIP / g729 isn't too bad either.
