What is the relationship between a Region and a Location?
A.
The Region codec parameter is used between a Region and its configured Locations.
B.
The Region setting for a Location sets the number of audio and video calls that Location can support.
C.
The codec parameter configured in the Region is only used between Regions and Location bandwidth is only used between Locations.
D.
The Region codec parameter is combined with Location bandwidth when communicating with other Regions.
Explanation:
Region settings specify voice codec that can be used for calls within a Region and between Regions. Locations provide Call Admission Control for centralized call processing systems. Calls between locations that travel over a WAN link most likely have limited available bandwidth. If the
number of calls placed over a WAN link is high enough to deplete the amount of available bandwidth on the link, the audio quality of all the calls over that WAN link is degraded due to over-subscription. You use Locations to avoid oversubscribing the WAN link such as decreasing the number of calls that are completed to a particular location, thus you define the total amount of bandwidth used for voice calls assigned to a location.
