Class of Service Options
Each line is assigned a Network Class of Service (NCOS) that controls the types of calls that can be made from that line. To allow a user to dial all domestic and international numbers at any time, for example, choose NCOS code number 1 (the default NCOS). Or if you want to restrict phone lines on courtesy telephones in public areas, NCOS codes 12 or 19 will more likely meet your needs. Our most commonly used NCOS options are listed below. Additional options are available for special circumstances.
Unless noted, all NCOS permit incoming calls, call transfers, and calls to University operators. All lines are blocked from making calls to 900/976 numbers. All lines permit emergency dialing.
To change one or more dialing restrictions for a line, contact your TSP (Telephone Support Provider).
