simultaneous voice calls handled by a single AP must be limited. This limit varies based on network conditions and handset manufacturer, and is typically provided in a manufacturer’s design guidelines.

Call admission control (CAC) is included with the Voice Services Module license. CAC lets the Mobility Controller limit the number of voice calls on an AP, and proactively move voice clients to a less-utilized AP. Aruba Mobility Controllers implement CAC by statefully following voice protocols and being aware of the voice utilization of a given AP. Per-SSID association limits for each AP also prevent a voice device from associating to a dedicated voice SSID when that AP has reached a pre-configured limit.

Comprehensive Voice Management

The Voice Services Module license adds extensive voice management functionality, providing detailed reporting and troubleshooting capabilities. Information is available at a glance via well-organized tables and graphs. Some of the capabilities include:

zPhone number association – SIP devices can be tracked and displayed by their associated phone number.

zCall quality tracking – Automatically calculates, displays and tracks the R-value for each SIP call being processed through the Aruba mobility controller.

zSIP authentication tracking – Tracks the registration of SIP devices with a IP PBX to determine if they are authenticated devices.

zCall detail records (CDRs) – Displays the calls made to or from Wi-Fi clients, including originator, terminator, termination reason, rejected and failed calls, duration, call quality, etc.

zCAC-based real-time information – Quickly determine call density, CAC state, and active calls.
