Explanation

Location parameters in Cisco Unified Communications Manager are the mechanism for implementing Call Admission Control (CAC) in a centralized call processing deployment. In this model, CUCM sits at a central site and remote branch phones register across a WAN link. Locations define the maximum audio and video bandwidth available on that WAN link. As calls are placed, CUCM deducts the codec bandwidth from the Location's pool; when the pool is exhausted, new calls are blocked (or rerouted) to prevent WAN oversubscription. This is CAC. Assigning directory numbers (A) is done via device configuration, not locations. While locations track bandwidth per call (B), the purpose is CAC, not mere specification. Alternate routing (D) is handled by route groups/lists.
