maximum length of the entire digit pattern is 152 characters. The available notations are
described in the table below:
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.
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
531 ), 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.
25.1.2 External Dial Plan File
The device can be loaded with a Dial Plan file with user-defined dialing plans. For more
information, see 'Dial Plan File' on page
530 .
