Any particular reason against using PRI from your telco?

Asterisk can handle multiple calls from the same IP without any worry.  Your 
main worry is the lack of real billing since you're terminating to analog 
PSTN instead of using PRI -- you have no way of actually knowing if the call 
was answered or not, so he'll be billed on every call.  I doubt you want to 
try and work with callprogress=yes.
