3Com VCX V7111 VoIP Gateway User Guide
Description
Disable [0] = Disable the current disconnect service (default).
Enable [1] = Enable the current disconnect service.
If the current disconnect service is enabled, the FXO gateway releases a call
when current disconnect signal is detected on its port, while the FXS gateway
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.
No [0] = Do not release the call.
Yes [1] = Call is released if RTP packets are not received for a predefined
timeout (default).
If enabled, the timeout is set by the parameter
BrokenConnectionEventTimeout, in 100 msec resolution. The default
timeout is 10 seconds: (BrokenConnectionEventTimeout =100).
This feature is applicable only if RTP session is used without Silence
Compression. If Silence Compression is enabled, the gateway does
not detect that the RTP connection is broken.
During a call, if the source IP address (from where the RTP packets
were sent) is changed without notifying the gateway, the gateway
filters these RTP packets. To overcome this issue, set
DisconnectOnBrokenConnection=0; the gateway does not 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.
The amount of time (in 100 msec units) an RTP packet is not received, after
which a call is disconnected.
The valid range is 1 to 1000. The default value is 100 (10 seconds).
Applicable only if DisconnectOnBrokenConnection = 1.
Currently this feature works only if Silence Suppression is disabled.
Yes [1] = The V7111 gateway disconnect calls in which silence occurs in both
(call) directions for more than 120 seconds.
No [0] = Call is not disconnected when silence is detected (default).
The silence duration can be set by the FarEndDisconnectSilencePeriod
parameter (default 120).
Duration of silence period (in seconds) prior to call disconnection.
The range is 10 to 28800 (8 hours). The default is 120 seconds.
Applicable to gateways, that use DSP templates 2 or 3.
Silence detection method.
None [0] = Silence detection option is disabled.
Packets Count [1] = According to packet count.
Voice/Energy Detectors [2] = According to energy and voice detectors
(default).
All [3] = According to packet count and energy / voice detectors.
