RE: PSTN Gateway service providers

[Christine Moe <>]

PRI is the most practical, with NFAS D-channel backup!  With the increase 
in rejection of calls (or folks just not answering) if the phone number is 
not visible, we need to be able to send the number to the LEC.  We also 
need to be able to control sending the number to the LEC..... both on a 
line basis and on a per call basis.

Not all LECs even have SS7 tariffed to offer service to CPE devices.  And 
the supporting hardware and software for the CPE site is significant in 
both $$ and effort.  It requires a big site with lots of traffic to justify.
