Parameter Description
Web/EMS: Enable Digit Delivery
to IP
[EnableDigitDelivery2IP]
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.
Web: Enable Digit Delivery to Tel
[EnableDigitDelivery]
Enables the Digit Delivery feature, which sends DTMF digits of
the called number to the device's port (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.
Notes:
For this parameter to take effect, a device reset is required.
The called number can include characters 'p' (1.5 seconds
pause) and 'd' (detection of dial tone). If character 'd' is used,
it must be the first 'digit' in the called number. The character
'p' can be used several times.
For example (for FXS/FXO interfaces), the called number can
be as follows: d1005, dpp699, p9p300. To add the 'd' and 'p'
digits, use the usual number manipulation rules.
To use this feature with FXO interfaces, configure the device
to operate in one-stage dialing mode.
If this parameter is enabled, it is possible to configure the
FXS/FXO interface to wait for dial tone per destination phone
number (before or during dialing of destination phone
number). Therefore, the parameter IsWaitForDialTone
(configurable for the entire device) is ignored.
The FXS interface send SIP 200 OK responses only after the
DTMF dialing is complete.
