Parameter Description
Tx DTMF Option Table
This
[TxDTMFOption]
ini file table parameter determines up to two preferred
transmit DTMF negotiation methods. The format of this
parameter is as follows:
[TxDTMFOption]
FORMAT TxDTMFOption_Index = TxDTMFOption_Type
For example:
TxDTMFOption 0 = 1;
TxDTMFOption 1 = 3;
;
[\TxDTMFOption]
This parameter can include up two indices.
Notes:
For a description on using ini file table parameters, refer
to ''Structure of ini File Table Parameters'' 191 on page .
Enables / disables the automatic muting of DTMF digits
when out-of-band DTMF transmission is used.
[DisableAutoDTMFMute]
[0]
= Automatic mute is used (default).
[1]
When DisableAutoDTMFMute = 1, the DTMF transport type
is set according to the parameter DTMFTransportType and
the DTMF digits aren't muted if out-of-band DTMF mode is
selected (TxDTMFOption =1, 2 or 3). This enables the
sending of DTMF digits in-band (transparent of RFC 2833)
in addition to out-of-band DTMF messages.
= No automatic mute of in-band DTMF.
Note:
Web/EMS: Enable Digit Delivery to IP
Usually this mode is not recommended.
The Digit Delivery feature enables sending DTMF digits to
the destination IP address after the Tel-to-IP call is
answered.
[EnableDigitDelivery2IP]
[0]
Disable = Disabled (default).
[1]
To enable this feature, modify the called number to include
at least one 'p' character. The device uses the digits before
the 'p' character in the initial INVITE message. After the call
is answered, the device waits for the required time (number
of 'p' multiplied by 1.5 seconds), and then sends the rest of
the DTMF digits using the method chosen (in-band or out-
of-band).
Enable = Enable digit delivery to IP.
Notes:
For this parameter to take effect, a device reset is
required.
The called number can include several 'p' characters
(1.5 seconds pause), for example, 1001pp699,
8888p9p300.
Enable Digit Delivery to Tel Enables the Digit Delivery feature, which sends DTMF
digits of the called number to the device's
[EnableDigitDelivery]
port
(phone line)
after the call is answered (i.e., line is off-hooked for FXS, or
seized for FXO) for IP-to-Tel calls.
[0]
Disable = Disabled (default).
[1] Enable = Enable Digit Delivery feature for the
FXO/FXS
device.
