User's Manual
Description

[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:

This parameter is applicable only to FXO and CAS.

This parameter is 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 goes to the next line.
