Parameter Description
Digit Mapping Rules
[DigitMapping]
Digit map pattern. If the digit string (dialed number) has matched one of the patterns in
the digit map, the gateway stops collecting digits and starts to establish a call with the
collected number
The digit map pattern contains up to 52 options separated by a vertical bar (|).
The maximum length of the entire digit pattern is limited to 152 characters.
Available notations:
• [n-m] represents a range of numbers
• ‘.’ (single dot) represents repetition
• ‘x’ represents any single digit
• ‘T’ represents a dial timer (configured by TimeBetweenDigits parameter)
• ‘S’ should be used when a specific rule, that is part of a general rule, is to be
applied immediately. For example, if you enter the general rule x.T and the specific
rule 11x, you should append ‘S’ to the specific rule 11xS.
For example: 11xS|00T|[1-7]xxx|8xxxxxxx|#xxxxxxx|*xx|91xxxxxxxxxx|9011x.T
Dial Tone Duration [sec]
[TimeForDialTone]
Time in seconds that the dial tone is played.
The default time is 16 seconds.
FXS gateway ports play the dial tone after phone is picked up; while FXO gateway ports
play the dial tone after port is seized in response to ringing.
Note 1: During play of dial tone, the gateway waits for DTMF digits.
Note 2: ‘TimeForDialTone’ is not applicable when Automatic Dialing is enabled.
Hot Line Dial Tone Duration
[HotLineDialToneDuration]
Duration (in seconds) of the Hotline dial tone.
If no digits are received during the Hotline dial tone duration, the gateway initiates a call
to a preconfigured number (set in the automatic dialing table).
The valid range is 0 to 60. The default time is 16 seconds.
Applicable to FXS and FXO gateways.
Enable Special Digits
[IsSpecialDigits]
Disable [0] = ‘*’ or ‘#’ terminate number collection (default).
Enable [1] = if you want to allow ‘*’ and ‘#’ to be used for telephone numbers dialed by
a user or entered for the endpoint telephone number.
Note: The # and * can always be used as first digit of a dialed number, even if you
select ‘Disable’ for this parameter.
Default Destination Number
[DefaultNumber]
Defines the telephone number that the gateway uses if the parameters ‘TrunkGroup_x’
or ’ChannelList‘ doesn’t include a phone number. The parameter is used as a starting
number for the list of channels comprising all hunt groups in the gateway.
