SIP User's Manual 3. Web-Based Management
Parameter Description
If the polarity reversal service is enabled, the FXS interface changes the
line polarity on call answer and then changes it back on call release.
The FXO interface sends a 200 OK response when polarity reversal
signal is detected (applicable only to one-stage dialing) and releases a
call when a second polarity reversal signal is detected.
Enable Current
Disconnect
[EnableCurrentDisconn
ect]
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, while 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.
Disconnect on Broken
Connection
[DisconnectOnBroken
Connection]
Determines whether the device releases the call if RTP packets are not
received within a user-defined timeout.
[0] No
[1] Yes (default)
Notes:
The timeout is set by the parameter BrokenConnectionEventTimeout.
This feature is applicable only if the RTP session is used without
Silence Compression. If Silence Compression is enabled, the device
doesn't detect a broken RTP connection.
During a call, if the source IP address (from where the RTP packets
are sent) is changed without notifying the device, the device filters
these RTP packets. To overcome this, set
DisconnectOnBrokenConnection to 0; the device doesn't detect RTP
packets arriving from the original source IP address and switches
(after 300 msec) to the RTP packets arriving from the new source IP
address.
Broken Connection
Timeout
[BrokenConnectionEve
ntTimeout]
The time period (in 100 msec units) that an RTP packet is not received
after which a call is disconnected.
The valid range is 1 to 1,000. The default value is 100 (i.e., 10 seconds).
Notes:
Applicable only if DisconnectOnBrokenConnection = 1.
Currently, this feature works only if Silence Suppression is disabled.
Disconnect Call on
Silence Detection
[EnableSilenceDisconn
ect]
Determines whether calls are disconnected after detection of silence.
[1] Yes = The device disconnects calls in which silence occurs (in both
call directions) for more than a user-defined time.
[0] No = Call is not disconnected when silence is detected (default).
The silence duration can be set by the FarEndDisconnectSilencePeriod
parameter (default 120).
Note: To activate this feature, set EnableSilenceCompression and
FarEndDisconnectSilenceMethod to 1.
