If you use the Sending Restrictions feature, this report monitors the feature's effectiveness and provides data for you to check to ensure that the appropriate communities in your organization are restricted. For example, if a community has a large number of calls that are blocked by sending restrictions, you might want to investigate further to determine if there is:
An administration problem. Are the correct communities being allowed or denied access?
A subscriber problem. Do subscribers know that they are restricted, and is the restriction appropriate?
Also, depending on how you use the feature, this report can provide security information if you are monitoring call activity involving sensitive communities.
