Only CAR administrators generate the Trunk Utilization
report. This report calculates the utilization reports for devices based on the
duration of calls that passed through the devices.
You can generate this report on an hourly, daily, or monthly
basis. The system calculates the utilization of a trunk for each hour in the
selected date range. For example, the system calculates the utilization of a
trunk between 11hrs-12hrs, using the formula, (Sum of the duration of calls
that used the trunk in that hour / (total seconds in an hour * maximum number
of ports in a trunk * number of days between the fromDate and toDate selected)
* 100).
Similarly, to get the utilization for each day in a week, the
system calculates the utilization using the formula, ((sum of the duration of
calls that used the trunk in a day) / (total seconds in each day * number of
each day between the fromDate and toDate selected * maximum number of ports in
a trunk) * 100).
In the case of monthly utilization reports, the system
calculates the utilization for each day in a month, using the formula, ((sum of
the duration of calls that used the trunk in a day) / (total seconds in each
day * number of each day between the fromDate and toDate selected * maximum
number of ports in a trunk) * 100).
Reports generate for each trunk that is chosen.
For calculation of the trunk utilization, the system uses the
port numbers from the CAR Trunk Configuration window. To find this window,
choose
.
You cannot take port details for H.323 trunks from the
Cisco Unified Communications Manager database because the H.323 port number
always equals zero in the database. The user must update H.323 trunk ports
information in the CAR Trunk Configuration window.
Be aware that the only port detail information that is taken
from the CAR Trunk Configuration window is only for those trunks that do not
have port details that are available or that show zero in the
Cisco Unified Communications Manager database.

Utilization reports.
