I have an existing cust. with a T1 for outgoing and DID(Norstar MICS 4.1). They want to upgrade the existing T to PRI. I understand that I have to purchase 'PRI enabler' and install the keycodes.
Can someone send me instructions on what I need to program in the Norstar after I input the keycodes? Also, does this have to be cut in conjunction with the carrier and how much downtime on the circuit?
