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 350.

[MaxDigits]
Defines the maximum number of collected destination number
digits that can be received (i.e., dialed) from the Tel side (analog)
when Tel-to-IP ISDN overlap dialing is performed (digital). 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 30for
digital.
Notes:
Instead of using this parameter, Digit Mapping rules can be
configured.
Dialing ends when any of the following scenarios occur:
waits between digits that are dialed by the user.
For ISDN overlap dialing: Defines the time (in seconds) that the
device waits between digits that are received from the PSTN or IP
during overlap dialing.
When this inter-digit timeout expires, the device uses the collected
digits to dial the called destination number.
The valid range is 1 to 10. The default is 4.

[IsSpecialDigits]
Determines whether the asterisk (*) and pound (#) digits can be
used in DTMF.
[0] Disable = Use '*' or '#' to terminate number collection (refer
