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.
