User's Manual

[1] Enable
Defines the duration (in seconds) to wait after an E1/T1 trunk
"Red" alarm (LOS / LOF) is raised, before the device
disconnects the SIP call. If this timeout expires and the alarm is
still raised, the device sends a SIP BYE message to terminate
the call. If the alarm is cleared before this timeout expires, the
call is not terminated, but continues as normal.
The range is 1 to 3600. The default is 0 (20 for E1 and 40 for
T1).
Determines whether a call is disconnected upon detection of a
busy tone (for ISDN).

[0] Disable = (Default) Do not disconnect call upon detection
of busy tone.

[1] Enable = Disconnect call upon detection of busy tone.
Notes:

This parameter is applicable only to ISDN protocols.

IP-to-ISDN calls are disconnected on detection of SIT tones
only in call alert state. If the call is in connected state, the
SIT does not disconnect the calls. Detection of busy or
reorder tones disconnects the IP-to-ISDN calls also in call
connected state.

For IP-to-CAS calls, detection of busy, reorder, or SIT tones
disconnect the calls in any call state.
Determines whether a call is disconnected upon detection of a
busy tone.

[0] Disable = Call is not disconnected upon detection of a
busy tone.

[1] Enable = (Default) Call is released upon detection of busy
or reorder (fast busy) tone.
Notes:

Digital interfaces: This parameter is applicable only to CAS
protocols.

Analog interfaces: This parameter is applicable only to FXO
interfaces.

This parameter is also applicable to the IP-to-IP application.

This parameter can also be configured in a Tel Profile.
Defines the FXO line polarity, required for DID signaling.

[0] = Positive line polarity

[1] = Negative line polarity

[2] = (Default) Auto - The device detects the polarity upon
power-up or upon insertion of the RJ-11 cable, and uses it as
a reference polarity.
Typically, if the RJ-11 cabling is connected correctly (without
crossing, Tip to Tip, Ring to Ring), the Tip line is positive
compared to the Ring line. In this case, set this parameter to 0.
With this configuration, the device assumes that the idle line
polarity is Tip line positive.
When the device receives a SIP INVITE, it checks the FXO line
polarity. If the polarity is "Reversed", it skips this FXO line and
