User's Manual 944 Document #: LTRT-89730
Mediant 3000
Parameter Description

[0] = (Default) Automatic mute is used.
 [1] = No automatic mute of in-band DTMF.
When the 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 (FirstTxDTMFOption
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.
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).
Notes:
 For the 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.
Enable Digit Delivery to Tel
[EnableDigitDelivery]
Enables the Digit Delivery feature, which sends DTMF digits of the
called number to the device's B-channel (phone line) after the call is
answered for IP-to-Tel calls.
 [0] Disable (default)
 [1] Enable
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 seconds ('p') and
plays the rest of the number (100) as DTMF digits.
Additional examples: 1664wpp102, 66644ppp503, and
7774w100pp200.
Notes:
 For the parameter to take effect, a device reset is required.
 The parameter can also be configured in a Tel Profile.
Special Digit
Representation
[UseDigitForSpecialDTMF]
Defines the representation for ‘special’ digits (‘*’ and ‘#’) that are used
for out-of-band DTMF signaling (using SIP INFO/NOTIFY).
 [0] Special = (Default) Uses the strings ‘*’ and ‘#’.
 [1] Numeric = Uses the numerical values 10 and 11.
