Gatekeeper CAC Example

Say for example we want to allow only 3 calls
gatekeeper
endpoint resource-threshold ! enable the max-calls command
arj reject-resource low ! allows endpoint to reject the limit of ARQ when the endpoint reaches its max no of calls
endpoint max-calls h323id gk_ucm_2 3 ! allow up to 3 calls

Call Admission Control - Bandwidth Allocation

A quick summary table on how much bandwidth used in the CAC calculation for 1 call in different codecs

	G.711	G.729
Gatekeeper CAC	128Kbps	16Kbps
Location CAC	80Kbps	24Kbps
RSVP CAC	96Kbps	40Kbps
