|
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 |
| |
| 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 |
| 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 |
