Question

across their WAN link to and from Madison. What can be done to the Location parameter for Madison to help alleviate this problem?

Options

ANothing, the audio bandwidth Location parameter for Madison is not related to the problem.
BIncrease the audio bandwidth setting in the Location configuration window for Madison.
CDecrease the audio bandwidth setting in the Location configuration window for Madison.
DRemove the audio bandwidth parameter in the Location configuration window for Madison.

Explanation

In CUCM Location-based CAC, the bandwidth value for a Location represents the total audio bandwidth available for calls traversing the WAN link to that site. If the WAN link to Madison is congested, it means too many concurrent calls are consuming more bandwidth than the link can support. Decreasing the audio bandwidth setting for Madison's Location tells CUCM that less bandwidth is available, causing it to deny new call admissions sooner (more aggressive CAC). This limits the number of concurrent calls permitted over the WAN, preventing oversubscription and alleviating congestion.
