Mediant 3000
Parameter Description
SDPs.
b. Sends DTMF packets using RFC 2833 payload type according
to the payload type in the received SDP.
c. Expects to receive RFC 2833 packets with the same payload
type as configured by the parameter RFC2833PayloadType.
d. Removes DTMF digits in transparent mode (as part of the
voice stream).

When TxDTMFOption is set to 0, the RFC 2833 payload type is set
according to the parameter RFC2833PayloadType for both
transmit and receive.

The table ini file parameter TxDTMFOption can be repeated twice
for configuring the DTMF transmit methods.

This parameter can also be configured in an IP Profile.
[DisableAutoDTMFMute] Enables the automatic muting of DTMF digits when out-of-band
DTMF transmission is used.

[0] = (Default) Automatic mute is used.

[1] = No automatic mute of in-band DTMF.
When this parameter is set to 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
set to 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.
Note: Usually this mode is not recommended.
Web/EMS: Enable Digit
Delivery to IP
[EnableDigitDelivery2IP]
Enables the Digit Delivery feature whereby DTMF digits are sent to
the destination IP address after the Tel-to-IP call is answered.

[0] Disable (default).

[1] Enable = Enable digit delivery to IP.
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).
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.
Web: Enable Digit
Delivery to Tel
EMS: Enable Digit
Delivery
[EnableDigitDelivery]
Enables the Digit Delivery feature, which sends DTMF digits of the
called number to the device's B-channel (phone line) after the call is
answered for IP-to-Tel calls.

[0] Disable (default).

[1] Enable = Enable Digit Delivery feature for the device (two-
stage dialing).
If the called number in IP-to-Tel call includes the characters 'w' or 'p',
the device places a call with the first part of the called number (before
'w' or 'p') and plays DTMF digits after the call is answered. If the
character 'w' is used, the device waits for detection of a dial tone
before it starts playing DTMF digits. For example, if the called number
is '1007766p100', the device places a call with 1007766 as the
destination number, then after the call is answered it waits 1.5
seconds ('p') and plays the rest of the number (100) as DTMF digits.
