Parameter
[DisableAutoDTMFMute]
User's Manual

[3] INFO (Cisco) = Sends DTMF digits according to Cisco
format.

[4] RFC 2833.

[5] INFO (Korea) = Sends DTMF digits according to Korea
Telecom format.
The format of the ini file table parameter is as follows:
[TxDTMFOption]
FORMAT TxDTMFOption_Index = TxDTMFOption_Type;
[\TxDTMFOption]
For example:
TxDTMFOption 0 = 1;
TxDTMFOption 1 = 3;
Notes:

DTMF negotiation methods are prioritized according to the
order of their appearance.

When out-of-band DTMF transfer is used ([1], [2], [3], or [5]),
the parameter DTMFTransportType is automatically set to 0
(DTMF digits are erased from the RTP stream).

When RFC 2833 (4) is selected, the device:
a. Negotiates RFC 2833 payload type using local and
remote 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.

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 314.
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.
