SIP User's Manual A. Configuration Parameters Reference
Parameter Description
according to packet count (FarEndDisconnectSilenceMethod
is set to 1).
 For this parameter to take effect, a device reset is required.
[BrokenConnectionDuringSilen
ce]
Enables the generation of the BrokenConnection event during a
silence period if the channel’s NoOp feature is enabled (using the
parameter NoOpEnable) and if the channel stops receiving NoOp
RTP packets.
 [0] Disable (default).
 [1] Enable.
Web: Trunk Alarm Call
Disconnect Timeout
[TrunkAlarmCallDisconnectTim
eout]
Defines the time (in seconds) to wait (in seconds) after an E1/T1
trunk "red" alarm (LOS/LOF) is raised before the device
disconnects the SIP call. Once this user-defined time elapses, the
device sends a SIP BYE message to terminate the call. If the
alarm is cleared before this timeout elapses, the call is not
terminated and continues as normal.
The range is 1 to 80. The default is 0 (20 for E1 and 40 for T1).
Web: Disconnect Call on Busy
Tone Detection (ISDN)
EMS: Isdn Disconnect On Busy
Tone
[ISDNDisconnectOnBusyTone]
Determines whether a call is disconnected upon detection of a
busy tone (for ISDN).
 [0] Disable = Do not disconnect call upon detection of busy
tone (default).
 [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.
Web: Disconnect Call on Busy
Tone Detection (CAS)
EMS: Disconnect On Detection
End Tones
[DisconnectOnBusyTone]
Determines whether a call is disconnected upon detection of a
busy tone (for CAS).
 [0] Disable = Do not disconnect call on detection of busy tone.
 [1] Enable = Call is released if busy or reorder (fast busy) tone
is detected on the device's FXO port (default).
Notes:
 Digital interfaces: This parameter is applicable only to CAS
protocols.
 Analog interfaces: This parameter is applicable only to FXO
interfaces.
 This parameter can also be configured per Tel Profile, using
the TelProfile parameter.
Polarity (Current) Reversal for Call Release (Analog Interfaces) Parameters
CLI: fxs-fxo > default-linepolarity-
state
[SetDefaultLinePolarityState]
Defines the FXO line polarity, required for DID signaling.
 [0] = Positive line polarity
 [1] = Negative line polarity
 [2] = Auto (default). The device detects the polarity upon
power-up or upon insertion of the RJ-11 cable, and uses it as
a reference polarity.
