Digit map (pattern) rules are defined using the DigitMapping parameter. The digit map
pattern can contain up to 52 options (rules), each separated by a vertical bar ("|"). The
maximum length of the entire digit pattern is 152 characters. The available notations are
described in the table below:
Table 24-1: Digit Map Pattern Notations
Notation Description
[n-m] Range of numbers (not letters).
. (single dot) Repeat digits until next notation (e.g., T).
x Any single digit.
Note: This notation does not apply in some scenarios when using the star (*)
or hash (#) key. For example, the key sequence of ** must be presented in the
dial plan as *x.s (instead of xx).
T Dial timeout (configured by the TimeBetweenDigits parameter).
S Short timer (configured by the TimeBetweenDigits parameter; default is two
seconds) that can be used when a specific rule is defined after a more general
rule. For example, if the digit map is 99|998, then the digit collection is
terminated after the first two 9 digits are received. Therefore, the second rule
of 998 can never be matched. But when the digit map is 99s|998, then after
dialing the first two 9 digits, the device waits another two seconds within which
the caller can enter the digit 8.
Below is an example of a digit map pattern containing eight rules:
DigitMapping = 11xS|00 [1-
7]xxx|8xxxxxxx|#xxxxxxx|*xx|91xxxxxxxxxx|9011x|xx.T
In the example, the rule "00 [1- 7]xxx" denotes dialed numbers that begin with 00, and then
any digit from 1 through 7, followed by three digits (of any number). Once the device
receives these digits, it does not wait for additional digits, but starts sending the collected
digits (dialed number) immediately.
Notes:
•
If you want the device to accept/dial any number, ensure that the digit map
contains the rule "xx.T"; otherwise, dialed numbers not defined in the digit map are
rejected.
•
If you are using an external Dial Plan file for dialing plans (see 'Dialing Plans for
Digit Collection' on page
376 ), the device first attempts to locate a matching digit
pattern in the Dial Plan file, and if not found, then attempts to locate a matching
digit pattern in the Digit Map (configured by the DigitMapping parameter).
•
It may be useful to configure both Dial Plan file and Digit Maps. For example, the
Digit Map can be used for complex digit patterns (which are not supported by the
Dial Plan) and the Dial Plan can be used for long lists of relatively simple digit
patterns. In addition, as timeout between digits is not supported by the Dial Plan,
the Digit Map can be used to define digit patterns (MaxDigits parameter) that are
shorter than those defined in the Dial Plan, or left at default. For example, “xx.T”
Digit Map instructs the device to use the Dial Plan and if no matching digit pattern,
it waits for two more digits and then after a timeout (TimeBetweenDigits
parameter), it sends the collected digits. Therefore, this ensures that calls are not
rejected as a result of their digit pattern not been completed in the Dial Plan.
