Parameter Description
■ If the device initiates a fax session using G.711 (option
2 or 3), a 'gpmd' attribute is added to the SDP in the
following format:
✔ For A-law: 'a=gpmd:8 vbd=yes;ecan=on'
✔ For Mu-law: 'a=gpmd:0 vbd=yes;ecan=on'
■ When the parameter is set to 1, 2, or 3, the parameter
FaxTransportMode is ignored.
■ When the parameter is set to 0, T.38 might still be used
without the control protocol's involvement. To
completely disable T.38, set FaxTransportMode to a
value other than 1.
■ For more information on fax transport methods, see
Fax/Modem Transport Modes.
■ The corresponding global parameter is IsFaxUsed.
'Enable Digit Delivery'
digit-delivery
[TelProfile_EnableDigitDelivery]
Enables the Digit Delivery feature, which sends DTMF
digits of the called number to the phone line (device's
analog port or digital B-channel) after the call is answered
(i.e., line is off-hooked for FXS or seized for FXO) for IP-to-
Tel calls.
■ [0] Disable (default)
■ [1] Enable
Digital interfaces: 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.
Note:
■ Analog interfaces: 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.
■ Analog interfaces: To use this feature with FXO
interfaces, configure the device to operate in one-stage
dialing mode.
