[Asterisk-Users] 911 and ISDN PRI

I've talked to the carrier (verizon), what they said is that the call is not
leaving my phone equipment. I tried to tell him that I'm getting an error
back from his system, but he insists that the channel never comes up. Their
answers was "talk to your telco vendor, its on their end". So I guess I'm
pretty much SOL when it comes to using 911 with the PRI.
Below is the debug, they wanted me to try all the DID numbers to see if it
worked on any of them (40 numbers) and the billing number, wouldn't work
with any of them.
