Configuring Call Admission Control
The call admission control feature allows you to count and limit the number of calls for a certain location. This can only be performed for server group elements.
When call admission control is enabled, the system monitors the start and stop time for each call. You can also set the session timeout which tells the system how long to wait before a call is considered dead.
For call admission control to work correctly, record route needs to be enabled on Cisco Unified SIP Proxy. If record route is not enabled, call admission control will not work reliably.
Choose Configure > Call Admission Control.
The system displays the Call Admission Control page.
Select if you want to enable or disable Call Admission Control.
Enter the Call Admission Control session timeout in minutes.
