Ironically, the BOC in this state (Southern Bell/BellSouth/AT&T) uses DMS offices almost exclusively. For some odd reason, upon divestiture, BellSouth elected to distance itself as far as possible from AT&T. They did so as far down as OSP hardware purchases. I'm not sure how they handled embedded iSDN/BRI accounts. Since most government agencies that I've ever encountered used CO-based Centrex services and ISDN phones, I'd think that somehow these sets continued to be supported by these DMS switches. Does anyone know if the DMS could emulate ESS protocol? I'm sure that since ISDN is a universal standard, it must have been possible.
