Abstract: Methods and apparatus, including computer program products, implementing and using techniques for managing telephone calls. Upon completion of a telephone call, a telephone services subscriber is provided with a post-call interface. The post call interface allows the subscriber to define how future telephone calls from the caller are to be managed. Instructions are received from the subscriber through the post-call interface. The instructions pertain to the management of future telephone calls from the caller. The received instructions are saved.

Abstract: Methods and apparatus, including computer program products, implementing and using techniques for verifying incoming telephone calls to a telephone services subscriber. An incoming telephone call from a caller is received. A time variable including one or more of a current date, a day-of-week, and a time-of-day is determined. One or more challenge questions is selected from a pre-defined schedule, in response to determining the time variable. The schedule includes challenge questions for different time variables. The caller is subjected to the one or more challenge questions. At least one challenge response to one or more of the selected challenge questions is received. It is determined whether the at least one challenge response was an expected correct response. If the at least one challenge response was correct, an action is taken with respect to the incoming telephone call.
