Mediant 2000 SIP

Table 6-1: Basic, Logging, Web and RADIUS Parameters (continues on pages 90 to 97)

ini File Field Name		Valid Range and Description
Web Parameter Name*
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
DisconnectOnBrokenConnect		0 = Don’t release the call.
ion		1 = Call is released If RTP packets are not received for a predefined timeout
[Disconnect on Broken		(default).
Connection]		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 will filter 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 will switch (after 300 msec) to the RTP packets arriving from the new source IP
		address.
BrokenConnectionEventTime		The amount of time (in 100 msec units) an RTP packets isn’t received, after which a
out		call is disconnected.
[Broken Connection Timeout]		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		1 = The gateway disconnect calls in which silence occurs in both (call) directions for
[Disconnect Call on Silence		more than 120 seconds.
Detection]		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.
FarEndDisconnectSilencePeri		Duration of silence period (in seconds) prior to call disconnection.
od		The range is 10 to 28800 (8 hours). The default is 120 seconds.
[Silence Detection Period]		Applicable to gateways, that use DSP templates 2 or 3.
FarEndDisconnectSilenceMet		Silence detection method.
hod		0 (None) = Silence detection option is disabled.
[Silence Detection Method]		1 (Packets Count) = According to packet count.
		2 (Voice/Energy Detectors) = N/A.
		3 (All) = N/A.
FarEndDisconnectSilenceThr	Threshold of the packet count (in percents), below which is considered silence by the
eshold	media gateway.
	The valid range is 1 to 100. The default is 8%.
	Note: Applicable only if silence is detected according to packet count
	(FarEndDisconnectSilenceMethod = 1).
Web-Related Parameters
DisableWebTask		0 = Enable Web management (default)
		1 = Disable Web management
