[asterisk-users] PRI vs "Digital Trunk"

[Joe Pukepail]

I don't know about what our LEC is calling a "digital trunk" but verizon
tried to offer me something like this for a location that they couldn't
offer a PRI, basically it was a just a voice T1 (24 channels), didn't
have features like Caller ID, setting outbound caller ID, ANI, etc.  YMMV.
