Dial Plan Configuration

Dial plans determine how dialed 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.
To edit a dial plan, click Voice on the menu bar, and then click Line 1 or Line 2 in the navigation tree. Scroll
down to the Dial Plan section, and then enter the digit sequences in the Dial Plan field.
Digit Sequences
A dial plan contains a series of digit sequences, separated by the pipe character: | .
The entire collection of sequences is enclosed within parentheses. Each digit sequence within the dial plan
includes a series of elements, which are individually matched to the keys that the user presses.
White space is ignored, but may be used for readability.
