<FONT FACE="Verdana, Helvetica, Arial"><SPAN STYLE='font-size:12.0px'>As Jason said, I would use SIP and not IAX, IAX might save you a little bandwidth but the implementions (all of them) are horrible and they sound like crap.<BR>
<BR>
There is also doing things like Least Cost Routing that will allow you to pick the best route for the call based on cost (and some other metrics) and send a call to the carrier based on that, should the call fail, the call is automatically re-routed to the other carrier for failover<BR>
<BR>
Contact me off list for an LCR implementation that I will be releasing in the very near future<BR>

I would use SIP and a SIP proxy or SIP with DNS SRV records.<BR>
