Location Configuration Settings
Use locations to implement call admission control in a centralized call-processing system. Call
admission control enables you to regulate audio quality and video availability by limiting the amount of
bandwidth that is available for audio and video calls over links between the locations. For more
information, refer to the
“Call Admission Control” chapter in the Cisco Unified Communications
Manager System Guide.
Note If you do not use call admission control to limit the audio and video bandwidth on an IP WAN link, an
unlimited number of calls can be active on that link at the same time. This situation can cause the audio
quality of each audio call and the video quality of each video call to degrade as the link becomes
oversubscribed.
Tip Do not confuse locations with geolocations. Locations, which you configure by using the System >
Location menu option, allow you to define entities that a centralized call-processing system uses to
provide call admission control (CAC). Geolocations, which you configure by using the System
>
Geolocation Configuration menu option, allow you to specify geographic locations that you use to
associate Cisco Unified Communications Manager devices for features such as logical partitioning.
In a centralized call-processing system, a single Cisco Unified Communications Manager cluster
provides call processing for all locations on the IP telephony network. The Cisco Unified
Communications Manager cluster usually resides at the main (or central) location, along with other
devices such as phones and gateways. The remote locations contain additional devices, but no Cisco
Unified Communications Manager. IP WAN links connect the remote locations to the main location.
