Table 2: Key performance indicators

KPI	Comment
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.
