An engineer wants to allow more calls on the WAN link from the head office to a branch. The region setting has been changed from G711 to G729. Which other configuration in Cisco Unified Communications Manager must be updated to accomplish this goal?
A. region
B. physical location
C. class of control
D. location
E. AAR group
The AAR Group isnt a management mechanism for either bandwidth or calls persay.
The AAR group is really a selection of WHERE the calls go when CAC has already been engaged. It doesnt care what the bandwidth or call allowance is, only where its going afterwards. I wouldnt really be using AAR for calls ON the WAN anyways, it would be for calls that are NOT going to the WAN because the WAN is unavailable.
I agree answer D
CUCM location defines the maximum audio/video bandwidth allowed into and out of a location, Calls are allowed
until the total bandwidth between the locations.
What is the difference between Region and Location in CUCM? –> Regions specifies the type of compression or bit rate can be used for voice and video calls between IP Phones. … –> Locations specifies the amount of bandwidth can be used for voice and video calls between IP Phones
I think the answer is Location:
check…
CUCM guide.
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.
I also think the Location is the good answer.
However, nothing else must be modified at all since the codec changed from wide to narrowband so more calls can be on the same amount of bandwith. If the change would be from G729 to G711 then Location settings also must be checked and modified.
