|
ClusterIncomingCall | Identifies a call where caller is not an internal extension. An Incoming call is |
| also: - An Inbound call - An |
|
|
ClusterInternalCall | An Internal Call is a call between 2 internal extensions, managed by one or |
| more CallManager Clusters, where the 2 Extension numbers (caller and |
| callee) are short internal numbers. |
| An Internal call, or Company call can be: |
| - An Outbound or Inbound call, |
| - A call between 2 IP phones from the same site, |
| - A call between 2 IP phones from different sites, |
| - A call between 1 IP phone and 1 legacy phone from the same site, |
| - A call between 1 IP phone and 1 legacy phone from different sites7 |
| Internal = IntrasiteIP OR IntersiteIP OR IntrasiteLegacyPBX OR |
| IntersiteLegacyPBX7 |
| - An |
| - An |
| An Internal call can never be: |
| - A call between an Internal Extension and any External PSTN Number. |
| Note: Internal extensions are managed through the UBA.xml adaptor |
| configuration file, where the variable ExtensionRange has to be defined. |
|
|
ClusterInternationalCall | Identifies a call where the caller is an internal extension and where the callee |
| is an International External PSTN number, according to the Numbering |
| Plan (NANP or Other prefixes). An International call is also: - An |
| Outbound call- An |
| TollBypassCall if a remote PSTN Gateway is involved in the Voice path |
|
|
ClusterIntersiteIPCall | Identifies a specific Internal Call where caller and callee are from different |
| location (site) and using a pure IP Network transit path (No PSTN Gateway |
| is involved in the voice Path). |
|
|
ClusterJitter | Provides an estimate of the statistical variance of the RTP data packet |
| interarrival time; measured in milliseconds.This metric comes from the |
| CMR table. Its set only once the call is established. This metric is only |
| available for IP Phones. |
|
|
ClusterLatency | Designates value that is an estimate of the network latency, expressed in |
| milliseconds. This value represents the average value of the difference |
| between the NTP timestamp indicated by the RTP Control Protocol |
| (RTCP) messages and theNTP timestamp of the receivers, measured when |
| these messages are received.Cisco CallManager obtains the average by |
| summing all the estimates then dividing by the number of RTCP messages |
| that have been received. Value of the Latency in |
| comes from the CMR table. Its set only once the call is established. This |
| metric is only available for IP Phones. |

ClusterLines | Total number of type 18 interfaces lines |
