Calling Party Number using Dial Plan File'' on page 689.
Digit Mapping Rules
[DigitMapping]
Defines the digit map pattern (used to reduce the dialing period
when ISDN overlap dialing). If the digit string (i.e., dialed number)
matches one of the patterns in the digit map, the device stops
collecting digits and establishes a call with the collected number.
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 include the
following:
 [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.
An example of a digit map is shown below:
11xS|00T|[1-7]xxx|8xxxxxxx|#xxxxxxx|*xx|91xxxxxxxxxx|9011x.T
In the example above, the last rule can apply to International
numbers: 9 for dialing tone, 011 Country Code, and then any
number of digits for the local number ('x.').
Notes:
 For ISDN interfaces, the digit map mechanism is applicable only
when ISDN overlap dialing is used (ISDNRxOverlap is set to 1).
 If the DialPlanIndex parameter is configured (to select a Dial
Plan index), then 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 rules
configured by the DigitMapping parameter.
 For more information on digit mapping, see ''Digit Mapping'' on
page 523.
Max Digits in Phone Num
[MaxDigits]
Defines the maximum number of collected destination number
digits that can be received from the Tel side when ISDN Tel-to-IP
overlap dialing is performed. When the number of collected digits
reaches this maximum, the device uses these digits for the called
destination number.
The valid range is 1 to 49. The default is 30.
Note: Instead of using the parameter, Digit Mapping rules can be
configured.
