Parameter Description
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.

If an ISDN phone user presses digits (e.g., for interactive
voice response / IVR applications such as retrieving voice
mail messages), ISDN Information messages received by
the device for each digit are sent in the voice channel to the
IP network as DTMF signals, according to the settings of the
TxDTMFOption parameter.

You can also configure this functionality per specific calls,
using IP Profiles (IpProfile_FirstTxDtmfOption and
IpProfile_SecondTxDtmfOption). For configuring IP Profiles,
see ''Configuring IP Profiles'' on page
304 .
[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
CLI: digit-delivery-2ip
[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
CLI: digit-delivery-2tel
[EnableDigitDelivery]
Enables the Digit Delivery feature, which sends DTMF digits of
the called number to the device's B-channel (digital) (phone
line) after the call is answered for IP-to-Tel calls.

[0] Disable (default)

[1] Enable
For digital interfaces: 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
