what protocol is the provider using?
NI1 = a protocol
NI2 = b protocol
o A = Custom or NI1. This is typically used when your T1 comes out of an AT&T
4ESS Central Office.
o B = NI2, and is typically used when your T1 comes out of a 5ESS Central Office
This is the only protocol capable of giving the customer NAME and number
Caller ID. You always prefer this protocol if the vendor can provide it!
If it's not coming up, you most likely don't match the provider.
protocol on ds1 form, trunk-group form, signal-group form
