Abstract

Call screening is provided by a call processing method, involving detecting a first call directed to the premises of a service subscriber requesting call processing instructions from a service control point in response to the first call, operating the service control point to instruct the signal switching point to temporarily park the first call at the signal switching point, and controlling the disposition of the first call as a function of a determination as to whether a second call to the service subscriber was answered by a machine or a human being.
