Digit Sequences - Cisco 8800 Series Manual

Digit Sequences

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.

Characters that represent a key that the user must press on the phone
keypad.
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.

2 9
A numeric range can include other characters. For example,
allows a user to press 3, 5, 6, 7, 8, or *.
A period indicates element repetition. The dial plan accepts
entries of the digit. For example,
0111, and so forth.
This format indicates that certain dialed digits are replaced by the
substituted characters when the sequence is transmitted. The dialed
digits can be zero to 9. For example:
<8:1650>xxxxxxx
When the user presses followed by a seven-digit number, the system
8
automatically replaces the dialed
dials 85550112, the system transmits 16505550112.
If the dialed parameter is empty and there is a value in the substituted
field, no digits are replaced and the substituted value is always
prepended to the transmitted string. For example:
<:1>xxxxxxxxxx
When the user dials 9725550112, the number
beginning of the sequence; the system transmits 19725550112.
