Valid Range and Description
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.
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.
The gateway's available Resources are calculated by dividing the
number of busy endpoints by the total number of available gateway
endpoints.
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.
Time interval (in seconds) that the gateway checks for resource availability.
The default is 10 seconds.
0 = Don't release the call.
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 doesn't 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 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.
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).
Applicable only if 'DisconnectOnBrokenConnection = 1'.
Currently this feature works only if Silence Suppression is disabled.
