Remember, you don't need to activate all 23 lines so if you just need 15

some of your coding a little different because you no longer make an
association between which port(s) ring and what number the caller
dialed to get here.
This is called DNIS (Dialed Number Identification System) (people don't
flame me for the ANI/DNIS thing OK? Not relevant for this discussion).
Not a flame :)
I think you are referring to DNIS vs DNID.
DNIS (Dialed Number Identification Service) is the number the caller
dialed. ANI (Automatic Number Identification) is the number the caller
called from.
PRI can also deliver ANI2 (aka Info Digits) which can (if the ANI
provider configured it) tell you what type of service the ANI came from
-- hospital, hotel, prison, cell, etc.
I've never gotten ANI2 working, so if you have, please enlighten me :)
IMNSHO, PRI beats the [EMAIL PROTECTED] out of any other T1 flavor.
(Is there another T1 flavour? I thought PRI was it :) BRI isn't T1 anymore)
T-1s do not have to be PRI. In fact many of them are not. You can have
a T-1 with a mix of signaling methods, FXO, FXS, E&M, E&M/Wink, loop
start, ground start, etc.
