ClusterIncomingCall Identifies a call where caller is not an internal extension. An Incoming call is
also: - An Inbound call - An Off-net call, coming from the PSTN
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 On-net call (pure IP Network transit)
- An Off-net call (IP to PSTN Gateway call).
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 Off-net call, routed towards the PSTN - Can be a
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 milli-seconds. This metric
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
