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

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.

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
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
