The correct answer is D. Add a media resource to transcode between available capabilities.. Regions in Cisco UCM limit the audio codec (and therefore bandwidth) allowed between two regions. When Region A and Region B are configured with bandwidth settings that result in incompatible codec selections-for example, one side negotiates G.711 and the other can only accept G.

Question

Refer to the exhibit. Regions have been configured for all major branches on the available circuit bandwidth. Some calls from Region A endpoints to Region B endpoints are failing to connect. How is the issue resolved?

Options

AUpdate the calling search space for affected endpoints to none.
BUpdate all regions to 8 kbps maximum audio bitrate.
CIncrease the number of available media termination points.
DAdd a media resource to transcode between available capabilities.

Explanation

Regions in Cisco UCM limit the audio codec (and therefore bandwidth) allowed between two regions. When Region A and Region B are configured with bandwidth settings that result in incompatible codec selections-for example, one side negotiates G.711 and the other can only accept G.729-calls fail because no common codec is available. A transcoder (a media resource in UCM's Media Resource Group) can convert between two different codecs in real time, bridging the gap between incompatible regions. Updating regions to a uniform 8 kbps would force G.729 everywhere and could break other calls; a transcoder is the targeted fix.
