My customer is starting PIN Codes to make outbound calls starting on the 21st of this month. I have moved all the analog lines to a diffrent class of service so they will not need pin codes for those lines (faxes and modems). My big questions is can I change just the NCOS to accept the PINS instead of the phones throughout the building? It would solve a programming nightmare for me considering their are about 1200 phones in the building.
