Dial Plan

A dial plan is a named set of normalization rules that translates phone numbers for a named location, individual user, or contact object into a single standard (E.164) format for purposes of phone authorization and call routing.

Normalization rule

Normalization rules define how phone numbers expressed in various formats are to be routed for each specified location, user, or contact object. The same dial string may be interpreted and translated differently depending on the location from which it is dialed and the person or contact object making the call. A set of normalization rules associated with a particular location constitutes a dial plan.
