ini File Field Name
Web Parameter Name
Valid Range and Description
EnableRAI
0 = Disable RAI (Resource Available Indication) service (default).
1 = Enable RAI service.
If RAI is enabled, an SNMP ‘acBoardCallResourcesAlarm’ Alarm Trap is sent if
gateway resources fall below a predefined (configurable) threshold.
RAIHighThreshold
High Threshold (in percentage) that defines the gateway‘s busy endpoints.
The range is 0 to 100.
The default value is 90%.
When the percentage of the gateway‘s busy endpoints exceeds the value
configured in High Threshold, the gateway sends an SNMP
‘acBoardCallResourcesAlarm’ Alarm Trap with a ‘major’ Alarm Status.
Note: The gateway’s available Resources are calculated by dividing the number
of busy endpoints by the total number of available gateway endpoints.
RAILowThreshold
Low Threshold (in percentage) that defines the gateway‘s busy endpoints.
The range is 0 to 100.
The default value is 90%.
When the percentage of the gateway’s busy endpoints falls below the value
defined in Low Threshold, the gateway sends an SNMP
‘acBoardCallResourcesAlarm’ Alarm Trap with a ‘cleared’ Alarm Status.
RAILoopTime
Time interval (in seconds) that the gateway checks for resource availability.
The default is 10 seconds.
Disconnect Supervision Parameters
DisconnectOnBrokenConne
ction
[Disconnect on Broken
Connection]
0 = Don’t release the call.
1 = Call is released If RTP packets are not received for a predefined timeout
(default).
Note 1: If enabled, the timeout is set by the parameter
‘BrokenConnectionEventTimeout’, in 100 msec resolution. The default timeout
is 10 seconds: (BrokenConnectionEventTimeout =100).
Note 2: This feature is applicable only if RTP session is used without Silence
Compression. If Silence Compression is enabled, the gateway doesn’t detect
that the RTP connection is broken.
Note 3: 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 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.
BrokenConnectionEventTim
eout
[Broken Connection Timeout]
The amount of time (in 100 msec units) an RTP packets isn’t received, after
which a call is disconnected.
The valid range is 1 to 1000. The default value is 100 (10 seconds).
Note 1: Applicable only if ‘DisconnectOnBrokenConnection = 1’.
Note 2: Currently this feature works only if Silence Suppression is disabled.
EnableSilenceDisconnect
[Disconnect Call on Silence
Detection]
1 = The gateway disconnect calls in which silence occurs in both (call)
directions for more than 120 seconds.
0 = 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’ to 1 and
‘FarEndDisconnectSilenceMethod’ to 1.
FarEndDisconnectSilenceP
eriod
[Silence Detection Period]
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.
