[Asterisk-Users] T1 passthrough/middleman

[Nathan Bell]

That sounds exactly like what I want to do. I've don't have a PRI line 
(although I'm going to press for getting one soon), but for now I would 
just like a couple of pointers in getting Asterisk's dial plan set up to 
just pass the calls from one T1 to another.

Thanks a million in advance.
