Call Admission Control (CAC)

CIC has built-in Call Admission Control on the SIP Line. It can be used in situations where you must limit the amount of calls that the system should place. Adding just one more call can degrade the voice quality of all the other active calls when there is not sufficient bandwidth to support it. In the example below, you can see that we have limited the CIC server to have a maximum of 10 calls associated with this SIP line. This setting does not account for bandwidth. The person doing the implementation must plan for the codec type and layer 2 overheard required.

Note:
CIC cannot guarantee the bandwidth needed for other activities on the WAN in this configuration.
