Digit Mapping Rules

[DigitMapping]
Defines the digit map pattern (used to reduce the dialing period when
ISDN overlap dialing for digital interfaces). 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.').
Note:
 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 569.
Max Digits in Phone Num

[MaxDigits]
Defines the maximum number of collected destination number digits
that can be received (i.e., dialed) from the Tel side (analog) or for
digital, 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 5 for analog and 30 for digital.
Note:
 Instead of using the parameter, Digit Mapping rules can be
configured.
 For FXS/FXO interfaces: Dialing ends when any of the following
scenarios occur:

Maximum number of digits is dialed

Interdigit Timeout (TimeBetweenDigits) expires

Pound (#) key is pressed
 Digit map pattern is matched
