This Use this object creates to create and configures configure a call admission control (CAC) profile providing the ability for each SIP registered or static endpoint to have individualized limits on the number of active calls and the call rate. A limit on active calls (CALL LIMIT) is applied to calls in either the ingress or egress direction, whereas policing controls (RATE, BURST-SIZE) apply to ingress and egress calls separately.
