2) Sends DTMF packets using RFC 2833 PT according to the PT
in the received SDP.
3) Expects to receive RFC 2833 packets with the same PT as
configured by the parameter RFC2833PayloadType.
4) Sends DTMF digits in transparent mode (as part of the voice
stream).

When TxDTMFOption is set to 0, the RFC 2833 PT is set
according to the parameter RFC2833PayloadType for both
transmit and receive.

The ini file table parameter TxDTMFOption can be repeated twice
for configuring the DTMF transmit methods.
This 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
[\TxDTMFOption]
For example:
TxDTMFOption 0 = 1;
TxDTMFOption 1 = 3;
Notes:

This parameter can include up two indices.

For a description on using ini file table parameters, refer to
''Structure of ini File Table Parameters''
Enables / disables 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 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.
Note: 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.

[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.
