This section displays all the details of Call Interval Statistics.

On SBC main screen, go to Monitoring > Trunks and Subscribers > Sessions > Call Interval Statistics. The Call Interval Statistics window is displayed.

Call Interval Statistics

By default only ten entries are displayed in a view. You can choose the number of entries to be displayed under the Show entries drop down box. Click  to expand the window to display more fields.

The Call Interval Statistics can be checked for each Address Context or for each Zone or for all the Address Contexts and Zones created. Use the drop-down box to select the desired Address Contexts and Zones.

Call Interval Statistics Parameters


Parameter


Description

NumberSpecifies the sequence number which identifies the interval for which the set of statistics is required.
NameSpecifies the name of the Call Interval Statistics.
Interval ValidA setting of 'true' indicates the interval contains valid data during the time interval. Each interval is for a configurable fixed time (default interval is 15 minutes) starting on the hour. For example, if the system starts at 12:05, the first interval at 12:15 will not be valid because it is less than the 15-minute interval. Subsequent intervals will be valid upon meeting the 15-minute time interval. System switch-overs also cause invalid intervals because data is lost during the interval.
  • false
  • true
TimeSystem up time when interval statistics is collected
In UsageUsage in the inbound direction for this trunk   group in seconds in the current interval. The trunk group usage is defined as   the time a trunk is seized to the time a trunk is released.
Out UsageSpecifies the usage in the outbound direction for this trunk group in seconds in the current interval. The trunk group usage is defined as the time a trunk is seized to the time a trunk is released.
In CallsNumber of completed inbound calls on this trunk group for the specified interval.
Out CallsNumber of completed outbound calls on this trunk group for the specified interval.
In Call AttemptsNumber of inbound call attempts on this trunk group for the specified interval.
Out Call AttemptsNumber of outbound call attempts on this trunk group for the specified interval.
Max Active CallsThe current high water mark of the total number of active calls in both inbound and outbound directions on the trunk group. This statistic applies to calls that are setting up, stable or tearing down. When a switch-over occurs from SBC-A to SBC-B in an HA scenario, the number of stable calls that were transferred from SBC-A to SBC-B equals the initial value of "maxActiveCalls" (immediately after the switch-over). Subsequent values are calculated and recorded accordingly.
Call Setup TimeTotal call setup time for all completed calls in inbound and outbound directions for this trunk group for specified interval measured in hundredths of a second.
Call SetupsTotal number of calls setup but not necessarily completed in the inbound and outbound directions for this trunk group for the specified interval.
Routing AttemptsNumber of routing attempts for this trunk group for the specified interval.
In Bw UsageSum of bandwidth usage (expected data rate in bits per second multiplied by   call duration in seconds) for every inbound call associated with this trunk   group for the specified interval.
Out Bw UsageSpecifies the usage in the outbound direction for this trunk group in seconds in the current interval. The trunk group usage is defined as the time a trunk is seized to the time a trunk is released.
Max Active Bw UsageHigh water mark bandwidth usage in either direction associated with   this trunk group for the specified interval.
Calls With Pkt OutageNumber of calls with a maximum packet outage whose duration exceeds the configured minimum for this trunk group for the specified interval.
Calls With Pkt Outage At EndNumber of calls whose maximum packet outage occurs at the end of the call for this trunk group for the specified interval.
Total Pkt OutageSummation of packet outage durations (in milliseconds) whose duration exceeds the configured minimum which is reported during the specified   performance interval.
Max Pkt OutageSingle longest maximum reported packet outage duration (in milliseconds) experienced during the specified performance interval for this trunk group.
Pod EventsNumber of Packet Outage Detection (POD) Events detected for this peer group   for the specified interval.
Playout Buffer GoodNumber of calls with all sub-intervals reporting GOOD playout buffer quality for this trunk group for the specified interval.
Playout Buffer PoorNumber of calls with all sub-intervals reporting POOR or better playout buffer quality for this trunk group for the   specified interval.
Playout Buffer UnacceptedNumber of calls with at least one sub-interval reporting UNACCEPTABLE playout buffer quality for this trunk group for the specified interval.
Sip Reg AttemptsCurrent number of SIP registration attempts on a trunk group for the specified interval.
Sip Reg CompletionsCurrent number of SIP registrations that have successfully completed on a trunk group for the specified interval.
Calls With Psx DipsNumber of calls that made a PSX Dip during the interval.
Total Psx DipsThe number of ERE Dips in the interval.
Active RegsInterval number of active registrations on this trunk group.
Max Active RegsMaximum active registrations on this trunk group (high-watermark achieved on this trunk group)
Active SubsCurrent number of active subscriptions on this trunk group.
Max Active SubsMaximum active subscriptions on this trunk group (high-watermark achieved on this trunk group).
Peak Call RateThe peak call arrival rate on a trunk group level within a specified interval.
