You might want to consider IAX vs. SIP if you decide to go that route. 
Another thing to consider might be to acquire your own 8xx numbers from 
a carrier that would allow you to repoint those numbers quickly to your 
own DIDs which you have contracted for with various IAX providers. That 
way if any particular provider goes down, you can easily and quickly 
reroute your traffic to another provider while not needing to touch your 
internal * configs. Of course the downside is that this will probably 
cost a little more per minute, but the disaster recovery capability 
might make it worthwhile depending on your SLAs with customers. 
Providers that I've found easy to work with (although haven't push 
significant traffic through  either) are Teliax and VoipJet.

Good Luck!
