Inbound Loss (percent) Out of all inbound traffic received by this entity, the percentage of PDUs
that: (a) contained defects which prevented them from being deliverable to a
higher-layer protocol (bad checksums, bad length, etc.), (b) were discarded
even though no errors are detected (i.e. due to congestion, policing, or
resource limitations), or (c) were discarded because they were of an
unknown or unsupported protocol.
Incoming 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
Interface Availability (percent) Interface availability percentage for a Cisco gatekeeper
Interface Bandwidth Utilization In (percent) Inbound bandwidth utilization percentage for a PSTN gateway interface
Interface Bandwidth Utilization Out (percent) Outbound bandwidth utilization percentage for a PSTN gateway interface
Interface Packet Loss (percent) Total percentage of packets lost for a gatekeeper interface
Interface Throughput In (kbps) Inbound interface throughput measured in kilobits per second
Interface Throughput Out (kbps) Outbound interface throughput measured in kilobits per second
Internal 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.
International 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
Jitter 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.
