Parameter Description
Web: Silence Detection Period
[sec]
EMS: Silence Detection Time Out
[FarEndDisconnectSilencePerio
d]
Duration of the silence period (in seconds) after which the call is
disconnected.
The range is 10 to 28,800 (i.e., 8 hours). The default is 120
seconds.
Note: For this parameter to take effect, a device reset is
required.
Web: Silence Detection Method
[FarEndDisconnectSilenceMeth
od]
Silence detection method.
 [0] None = Silence detection option is disabled.
 [1] Packets Count = According to packet count.
 [2] Voice/Energy Detectors = .
 [3] All = .
Note: For this parameter to take effect, a device reset is
required.
[FarEndDisconnectSilenceThres
hold]
Threshold of the packet count (in percentages) below which is
considered silence by the device.
The valid range is 1 to 100%. The default is 8%.
Notes:
 Applicable only if silence is detected according to packet
count (FarEndDisconnectSilenceMethod is set to 1).
 For this parameter to take effect, a device reset is required.
[BrokenConnectionDuringSilenc
e]
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.

tone.
 [1] Enable = Call is released if busy or reorder (fast busy)
tone is detected on the device's FXO port (default).
Note: This parameter is applicable only to FXO interfaces.
Polarity (Current) Reversal for Call Release (Analog Interfaces) Parameters
Web: Enable Polarity Reversal
EMS: Enable Reversal Polarity
[EnableReversalPolarity]
Enables the polarity reversal feature for call release.
 [0] Disable = Disable the polarity reversal service (default).
 [1] Enable = Enable the polarity reversal service.
If the polarity reversal service is enabled, the FXS interface
changes the line polarity on call answer and then changes it

reversal signal is detected (applicable only to one-stage dialing)
and releases a call when a second polarity reversal signal is
detected.
