Voice Calls
Voice usage on an ISDN line is billed the same as your current voice telephone line. The ISDN voice
calls will be billed in accordance with your chosen residence or business exchange plan.
There is no charge for voice calls made within a NYNEX Intellipath Digital Centrex or Centrex
Plus system.

is an inter-office call. For calls to destinations outside the 207 area, consult your long distance
carrier. There is no charge for CSD calls made within a NYNEX IntelliPath system. Ciruit Switched
