CAC is used to allocate enough bandwidth for the number of calls that are allowed on the VoIP network.
CAC is used to protect the quality of the voice calls by preventing call establishment if enough resources are not available on the network.
CAC provides queuing mechanisms for voice calls if the packets exceed the configured or budgeted rate.
In a VoIP network the CAC can be replaced with the LLQ QoS mechanism if it has been properly implemented.
