MP-11x & MP-124
Parameter Description

[3] INFO (Cisco) = Sends DTMF digits according to Cisco
format.

[4] RFC 2833.

[5] INFO (Korea) = Sends DTMF digits according to Korea
Telecom format.
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.

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).
