Periodic Callers

Periodic Callers neglects frequency of spam calls by placing a time boundary to distinguish valuable calls.

In the below example we set the boundary to 2 week and we see those callers who most occasioned at 2 weeks intervals. For instance: Great Customer has called at least once every 2 weeks for at least 7 2 week intervals. This has more value than a number that calls 7 times in one day.
