Tx DTMF Option
[TxDTMFOption]
One or more preferred Transmit DTMF negotiation methods.
You can select:
Not Supported [0] = DTMF is sent according to the ‘DTMFTransportType’
parameter (default).
H.245 User Input [1].
H.245 Signal Method [2].
Q.931 Info Message [3].
RFC 2833 [4].
Note 1: DTMF negotiation methods are prioritized according to the order of their
appearance.
Note 2: If fast connect is used, you need to open H.245 channel to enable sending
DTMF digits using this channel.
ini file note: The DTMF transmit methods are defined using a repetition of the
same (TxDTMFOption) parameter (up to four options can be provided).
For information on DTMF transport types, refer to Section
8.2 on page 260.
RFC 2833 Payload Type
[RFC2833PayloadType]
The RFC 2833 DTMF relay dynamic payload type.
Range: 96 to 99, 106 to 127; Default = 96
The 100, 102 to 105 range is allocated for AudioCodes proprietary usage.
Note: Cisco is using payload type 101 for RFC 2833.
Max Digits in Phone
Number
[MaxDigits]
Note: Digit Mapping Rules
can be used instead.
Maximum number of digits that can be dialed.
The valid range is 1 to 49.
The default value is 5.
Note: Dialing ends when the maximum number of digits is dialed, the Interdigit
Timeout expires, the '#' key is dialed, or a digit map pattern is matched.
Default Destination Number
[DefaultNumber]
Defines the telephone number that the gateway uses if the parameter
‘TrunkGroup_x’ 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.
Inter Digit Timeout
[TimeBetweenDigits]
Time in seconds that the gateway waits between digits dialed by the user. When
the Inter-digit Timeout expires, the gateway attempts to dial the digits already
received.
The valid range is 1 to 10 seconds. The default value is 4 seconds.
Dial Tone Duration
[TimeForDialTone]
Time in seconds that the dial tone is played.
The default time is 16 seconds.
FXS module ports play the dial tone after phone is picked up; while FXO module
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: ‘Dial Tone Duration’ is not applicable when Automatic Dialing is enabled.
Hotline Dial Tone Duration
[HotLineToneDuration]
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.
Note: Applicable to FXS and FXO modules.
