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.

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.

The ini file table parameter TxDTMFOption can be repeated twice
for configuring the DTMF transmit methods.

This parameter can also be configured per IP Profile, using the
IPProfile parameter (see 'Configuring IP Profiles' on page 219).
Enables the automatic muting of DTMF digits when out-of-band DTMF
transmission is used.

[0] = Automatic mute is used (default).

[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.
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 = Disabled (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.
Enables the Digit Delivery feature, which sends DTMF digits of the
called number to the device's port (analog)/B-channel (digital) (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.
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
