This section includes information that you must understand about dial plans, and procedures to configure your
own dial plans.
The Cisco IP Phone has various levels of dial plans and processes the digits sequence.
When a user presses the speaker button on the phone, the following sequence of events begins:
1.
The phone begins to collect the dialed digits. The interdigit timer starts to track the time that elapses
between digits.
2.
If the interdigit 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
Voice
>
Ext(n)
under the
Dial Plan
section.
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.
Function

Characters that represent a key that the user must press on the phone
keypad.
0 1 2 3 4 5 6 7 8 9 0 * #
Any character on the phone keypad.

Characters within square brackets create a list of accepted key presses.
The user can press any one of the keys in the list.
A numeric range, for example,
[2-9]
allows a user to press any one
digit from
2

.
A numeric range can include other characters. For example,
[35-8*]
allows a user to press 3, 5, 6, 7, 8, or *.

A period indicates element repetition. The dial plan accepts
0
or more
entries of the digit. For example,
01.
allows users to enter 0, 01, 011,
0111, and so forth.
