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.
FunctionDigit Sequence
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.x
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 through 9.
A numeric range can include other characters. For example, [35-8*]
allows a user to press 3, 5, 6, 7, 8, or *.
[sequence]
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.
. (period)
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 8 followed by a seven-digit number, the system
automatically replaces the dialed 8 with the sequence 1650. If the user
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 1 is added at the
beginning of the sequence; the system transmits 19725550112.
<dialed:substituted>
An intersequence tone played (and placed) between digits plays an
outside line dial tone. For example:
9, 1xxxxxxxxxx
An outside line dial tone plays after the user presses 9. The tone
continues until the user presses 1.
