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.

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, which are
individually matched to the keys that the user presses.
