User's Manual
The default is undefined.
Notes:

Call pick-up is configured only for FXS endpoints pertaining
to the same Trunk Group.

This parameter is applicable only to FXS interfaces.
Defines a string prefix (e.g., '9' dialed for an external line) that
when dialed, the device plays a secondary dial tone (i.e., stutter
tone) to the FXS line and then starts collecting the subsequently
dialed digits from the FXS line.
The valid range is a one-character string. The default is an
empty string.
Notes:

You can enable the device to add this string as the prefix to
the collected (and sent) digits, using the parameter
AddPrefix2ExtLine.

This parameter is applicable only to FXS interfaces.
Determines whether the prefix string for accessing an external
line (defined by the parameter Prefix2ExtLine) is added to the
dialed number as the prefix and together sent to the IP
destination (Tel-to-IP calls).

[0] = Disable (default)

[1] = Enable
For example, if this parameter is enabled and the prefix string
for the external line is defined as "9" (using the parameter
Prefix2ExtLine) and the FXS user wants to make a call to
destination "123", the device collects and sends all the dialed
digits, including the prefix string, as "9123" to the IP destination
number.
Note: This parameter is applicable only to FXS interfaces.
Determines the hook-flash key sequence for FXS interfaces.

[0] Flash hook = (Default) Only the phone's flash button is
used, according to the following scenarios:

During an existing call, if the user presses the flash
button, the call is put on hold; a dial tone is heard and
the user is able to initiate a second call. Once the
second call is established, on-hooking transfers the first
(held) call to the second call.

During an existing call, if a call comes in (call waiting),
pressing the flash button places the active call on hold
and answers the waiting call; pressing flash again
toggles between these two calls.

[1] Sequence 1 = Sequence of flash and digit:

Flash + 1: holds a call or toggles between two existing
calls

Flash + 2: makes a call transfer.

Flash + 3: makes a three-way conference call (if the
Three-Way Conference feature is enabled, i.e., the
parameter Enable3WayConference is set to 1 and the
parameter 3WayConferenceMode is set to 2).
