Description: This attribute specifies how to map the numbering plan indication and the type of number into the Vncs database diallingPlan0. For more information refer to NTP 241-7001-4xx Voice Networking Users Guide. There are three numbering plans that are allowed, unknown, E.164, and private. Within each of these, there are eight possible type of numbers. Since the name for the type of numbers for the private numbering plans varies from protocol to protocol, a generic scheme has been adopted. unknown means that the sending and receiving switches have no knowledge of the numbering plan. international means that the sending switch has identified the number format as matching the E.164 international dialling. national means that the sending switch has identified the number as conforming to the E.164 national dialling plan subscriber means that the number is the address of a customer conforming to the local public network. p0, p1, p2, p3, p4, p5, p6 and p7 are private numbering plans, with a type of number zero to seven. casUnknown means any number received from a Channel Associated Signalling (CAS) trunk.
