Call Admission Control Report
Topic Last Modified: 2011-02-01
The Call Admission Control Report provides a list of peer-to-peer and conference activities that use call admission control (CAC). By using CAC, you can determine whether you should allow real-time communications sessions, such as voice or video calls, based on bandwidth constraints.
Filters
Filters provide a way for you to return a more finely-targeted set of data or to view the returned data in different ways. For example, the Call Admission Control Report enables you to filter calls by the user who initiated the call or by the user who was being called. You can also choose how data should be grouped. In this case, calls are grouped by hour, day, week, or month.
The following table lists the filters that you can use with the Call Admission Control Report.
