KPI	Comment
ClusterLocalCall	Identifies a call where the caller is an internal extension and where the callee
	is a Local External PSTN number, according to the Numbering Plan
	(NANP or Other prefixes). A Local call is also:- An Outbound call - An
	Off-net call, routed towards the PSTN - Can be a TollBypassCall if a remote
	PSTN Gateway is involved in the Voice path
	Note: Internal extensions are managed through the UBA.xml adaptor
	configuration file, where the variable ExtensionRange is defined. In order to
	be able to know whether or not a call will be charged as a Local call, an
	additional variable needs to be set in the UBA.xml adaptor configuration
	file. If the first N digits match for this particular site with one of the number
	configured in this list, then the call is tagged as Local
ClusterLongDistanceCall	Identifies a call where the caller is an internal extension and where the callee
	is a LongDistance External PSTN number, according to the Numbering
	Plan (NANP or Other prefixes). A Long Distance cal call is also: - An
	Outbound call - An Off-net call, routed towards the PSTN - Can be a
	TollBypassCall if a remote PSTN Gateway is involved in the Voice path
ClusterMOS	Mean Opinion Score. This is an high level metric. Note: There is no
	algorithm for Mean Opinion Score calculations. This is a subjective metric
	from the end user point of view. In voice communications, particularly
	Internet telephony, the mean opinion score (MOS) provides a numerical
	measure of the quality of human speech at the destination end of the circuit.
	The scheme uses subjective tests (opinionated scores) that are
	mathematically averaged to obtain a quantitative indicator of the system
	performance. To determine MOS, a number of listeners rate the quality of
	test sentences read aloud over the communications circuit by male and
	female speakers. A listener gives each sentence a rating as follows: - 1 bad; -
	2 poor; - 3 fair; - 4 good; - 5 excellent. The MOS is the arithmetic mean of
	all the individual scores, and can range from 1 (worst) to 5 (best). In our
	context, our MOS calculation is based on the consolidation of Jitter, Latency
	and Packets Lost values which give us a good overview of the real MOS
	value.
ClusterNbPacketsLost	Number of Packets Lost by the subelement during a call. This metric comes
	from the CMR table. Its set only once the call is established. This metric is
	only available for IP Phones.
ClusterNbPacketsReceived	Number of Packets Received by the subelement during a call. This metric
	comes from the CMR table. Its set only once the call is established. This
	metric is only available for IP Phones.
ClusterNbPacketsSent	Number of Packets Sent by the subelement during a call. This metric comes
	from the CMR table. Its set only once the call is established. This metric is
	only available for IP Phones.
ClusterOffNetCall	Identifies a call where at least one PSTN Gateway is involved in the Voice
	path, with the following criteria: - Inbound or Outbound call - Internal or
	call to/from PSTN number - Intersite or Intrasite Legacy PBX Call
ClusterOnNetCall	Identifies a call where the caller is an internal extension and where the callee
	is also an internal extension, from the same site or different sites, with the
	following criteria: - Outbound call - Internal call - Intersite or Intrasite IP
	Call - No PSTN Gateway is involved in the Voice path - This is a pure IP to
	IP call
