The Voice Interface Utilization report provides information about usage levels on voice gateway-type media devices. Information in this report is useful for assessing:
Note: The Voice Interface Utilization report supports Cisco environments only.
Verify that all known gateway voice interfaces have the number of channels correctly configured. UC Monitor uses the known channel capacity for each interface to calculate usage as a percentage of capacity. This report is less accurate when the device MIB incorrectly reports the capacity of the gateway voice channel.
Interfaces that are deleted from the system do not appear in the report. However, some deleted interfaces have data. You can use the Settings link to include deleted interfaces in the report.
The Voice Interface Utilization page provides the following information.
The usage of all gateway voice interfaces on all voice gateway devices. Shown as a percentage of capacity over a day, a week, or a month.
Usage is computed by multiplying the time frame by the number of channels in a gateway or interface. For one hour, a single channel can provide 60 call minutes. Thus, a full PRI interface (23 channels) can support the following usage:
23 channels x 60 minutes/hour = 1380 call minutes/hour = 33120 call minutes/day
The number of call minutes used to calculate usage statistics. This value provides a sense of the scope of activity and helps determine the significance of the data as it relates to sample size.
The Interface Utilization Details table is not displayed by default. You can use the Settings link to display the table.
The hour from which the detailed data was collected.
The number of minutes that calls were active during the selected time period. By default, applies to all call minutes logged on all gateways in the system.
The number of call minutes that were supported during the selected time period. The capacity is discovered during monitoring or is manually supplied during configuration.
The usage during the time period. Expressed as a percentage of available capacity.
