Table 5-4: DTMF & Dialing Parameters (continues on pages 54 to 56)
Parameter Description

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
H.245 User Input [1].
H.245 Signal Method [2].
Q.931 Info Message [3].
RFC 2833 [4] (default).
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 8.3 on page 153.
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.
You can enter a value from 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 parameters ‘TrunkGroup_x’
or ’ChannelList‘ don’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.
You can enter a value of 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 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: ‘Dial Tone Duration’ is not applicable when Automatic Dialing is enabled.
HotLineDialToneDuration
[Hotline Dial Tone Duration]
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 5 seconds.
Applicable to FXS and FXO gateways.
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 8 options, each up to 22 characters that are
separated by a vertical bar (|).
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
