SIP User's Manual
Enables call release upon detection of a Current Disconnect
signal.
[0] Disable = Disable the current disconnect service
(default).
[1] Enable = Enable the current disconnect service.
If the current disconnect service is enabled:
The FXO releases a call when a current disconnect signal is
detected on its port.
The FXS interface generates a 'Current Disconnect Pulse'
after a call is released from IP.
The current disconnect duration is determined by the parameter
CurrentDisconnectDuration. The current disconnect threshold
(FXO only) is determined by the parameter
CurrentDisconnectDefaultThreshold. The frequency at which
the analog line voltage is sampled is determined by the
parameter TimeToSampleAnalogLineVoltage.
Defines the voltage change slope during polarity reversal or
wink.
[0] = Soft reverse polarity (default).
[1] = Hard reverse polarity.
Notes:
This parameter is applicable only to FXS interfaces.
Some Caller ID signals use reversal polarity and/or Wink
signals. In these cases, it is recommended to set
PolarityReversalType to 1 (Hard).
For this parameter to take effect, a device reset is required.
The duration (in msec) of the current disconnect pulse.
The range is 200 to 1500. The default is 900.
Notes:
This parameter is applicable for both FXS and FXO
interfaces.
The FXO interface detection window is 100 msec below the
parameter's value, and 350 msec above the parameter's
value. For example, if this parameter is set to 400 msec,
then the detection window is 300 to 750 msec.
For this parameter to take effect, a device reset is required.
Determines the line voltage threshold which, when reached, is
considered a current disconnect detection.
The valid range is 0 to 20 Volts. The default value is 4 Volts.
Notes:
This parameter is applicable only to FXO interfaces.
For this parameter to take effect, a device reset is required.
