Call Admission Control

The call admission control feature enables you to control the audio quality and video quality of calls over a wide-area (IP WAN) link by limiting the number of calls that are allowed on that link at the same time. Audio and video quality can begin to degrade when toomany active calls exist on a link and the amount of bandwidth is oversubscribed. Call admission control regulates audio and video quality by limiting the number of calls that can be active on a particular link at the same time. The Call Admission Control feature controls number of calls based on resources and bandwidth, proactively reserve resources for good quality video calls, ensures that traffic adheres to QoS policies within each network. CUBE provides different CAC mechanisms that are based on: • Total Calls, CPU, or Memory • Call Spike Detection • Maximum Calls per Destination • Dial-peer or Interface Bandwidth
