If you want service to be as reliable as the PSTN then you have to use 
the PSTN.

I feel that sending calls over the Internet is just silly if you want as 
close to %100 uptime as you can.

My customers use PRIs with VoIPoInternet as a failover in case the PRI 
goes down or all channels are in use on the PRI.

I am not saying that VoIP is unreliable.  It is very reliable -- when 
you control the lines and routers between you and the PSTN.

I'm saying that the Internet is not reliable.

My customers route calls over point to point T-1s all the time with no 
issues.

Teliax seems to one of the better ITSPs.
