Configure Dial Plan

Dial plans determine how the digits are interpreted and transmitted. They also determine whether the
dialed number is accepted or rejected. You can use a dial plan to facilitate dialing or to block certain
types of calls such as long distance or international.
The dial plans can be configured on the IP phone by using the phone web user interface.
This section includes information that you need to understand dial plans, as well as procedures for

Digit Sequences

A dial plan contains a series of digit sequences, separated by the | character. The entire collection of
sequences is enclosed within parentheses. Each digit sequence within the dial plan consists of a series
of elements that are individually matched to the keys that the user presses.
White space is ignored, but can be used for readability.

The phone begins collecting the dialed digits. The inter-digit timers starts tracking the time that
elapses between digits.
If the inter-digit timer value is reached, or if another terminating event occurs, the phone compares
the dialed digits with the IP phone dial plan. (This dial plan is configured in the phone web user
interface in the Voice tab > Extension under the Dial Plan section.)
