There are eight 'Summary Period' PBX Statistics objects, which each display statistics collected over a different time interval. Note that the summary periods are preconfigured; you cannot change the summary periods or create new 'Summary Period' PBX Statistics objects. All the 'Summary Period' PBX objects have the same fields. All the fields are read only and there are no management actions associated with these objects.

The fields in this object refer to numbers of "lines/channels" for the PBX. The meaning of "lines/channels" depends on the PBX's Call Agent signaling type, as follows.
|
Counter type statistics record the total count of events (or time) during the particular time interval. High and Low type statistics record the highest or lowest value of the field reached during the particular time interval. Gauge type statistics show the average value of the field during the particular time interval, with a sampling rate of once every 5 minutes. Gauge statistics for the current and previous 5 minute time intervals are therefore a single snapshot value. Usage type statistics record the call usage in CCS (Centa Call Seconds): the total call time, in hundreds of seconds. 100 seconds = 1 CCS.

Call attempts - count of originating call attempts | Count | The number of attempts that have been made to originate a call from this PBX. |
Call attempts - count of terminating call attempts | Count | The number of call attempts to deliver a call on this PBX. |
Call attempts - count of terminating call attempts answered | Count | The number of call attempts to deliver a call to this PBX where call setup was completed by call control. Typically, this would mean that the subscriber has answered. |

This includes calls forwarded using Busy Call Forwarding, alerted using Call Waiting and not answered, or rejected because the call limit on a DISA Number or DID Range had been reached. |
Call attempts - count of terminating call attempts not answered | Count | The number of call attempts where the PBX did not appear to be busy and the call was not answered. This may include Call Service activations which cause alerting to cease before the call is abandoned, such as forwarded calls (except Busy Call Forwarding) and those handled by other call services. |
Call usage - all calls | Usage | The duration of all calls on this PBX, in CCS. |
Call usage - originating calls | Usage | The duration of all calls originating on this PBX, in CCS. |
Call usage - terminating calls | Usage | The duration of all calls terminating on this PBX, in CCS. |
