Version 7.2 1181 Mediant 800B Gateway & E-SBC
User's Manual 72. Configuration Parameters Reference
Parameter Description
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 583.
Max Digits in Phone Num
configure voip > gateway dtmf-supp-
service dtmf-and-dialing > mxdig-b4-
dialing
[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
Inter Digit Timeout for Overlap
Dialing
configure voip > gateway dtmf-supp-
service dtmf-and-dialing > time-btwn-
dial-digs
[TimeBetweenDigits]
Analog: Defines the time (in seconds) that the device waits
between digits that are dialed by the user.
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.
Enable Special Digits
configure voip > gateway dtmf-supp-
service dtmf-and-dialing > special-
Determines whether the asterisk (*) and pound (#) digits can
be used in DTMF.
[0] Disable = Use '*' or '#' to terminate number collection
