Dial plan configured using XML
In XML, the dial plan is named as a DigitMap, which is a string of characters with a 
length limit of 1024 bytes. A dial plan can consist of several dial plan tokens. Each 
token is a component of the overall dial plan. Each dial plan token is limited to 28 
bytes in length. The following is an example of a digit map, and is the default dial 
plan if no other plan is configured:
<DigitMap> 
(***xx|***xx|*xx*x.#|*xx*x.*xx#|*xx*x.*x#|*31*xxxxxxxx|*xx#|#xx#|*#x
x#|#001|x.T)</DigitMap>
This dial plan consists of three dial plan tokens:
1 (***xx|*xx*x.#|*xx*x.*xx#|
2 xx*x.*x#|*31*xxxxxxxx|
3 *xx#|#xx#|*#xx#|#001|x.T)
Pattern elements, 
symbol, or modifier
Representation
0-9, *, #, (,), [,], | Dialed digits or characters
x Any numeric string with any length, including 0
x{n} A digit in the range 0-9 followed by digits with a length of n; for example, 
123x{5} equals 123xxxxx.
[ ] A set of digits enclosed in brackets “[ ]” represents the occurrence of any 
of the enclosed digits, for example [1-5] indicates only numbers 1 to 5 are 
acceptable
. A pattern element followed by a dot signifies zero of more occurrences of 
the element. 
() The digit map must begin and end with matching parentheses. Nested 
parentheses are not allowed in the digit map for Package C, D, E, F, and G 
ONTs.
| A sequence of pattern elements separated by | matches the any one of the 
elements in the sequence.
T The T modifier represents the application of the critical dial timer (4 s). A 
pattern element followed by the T modifier matches if an only if the critical 
timer expires at that point. There can be multiple critical timers in the dial 
plan table, for example, (123x.T|456x.T|**xxx.T)
Note 1 — Alphabetic symbols in the ONT digit map are not case 
sensitive.
Note 2 — The digit_map SIP parameter is a required parameter; it has 
no default value. A digit map must be customized for each SIP 
implementation based on the features of the SIP server in the network.
