Use this profile to 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, bandwidth size, call rates, over-subscription amounts, burst sizes, etc.

Note

To calculate fill rate and bucket size, refer to Token Bucket Policers.
