Abstract
Non-toll calls originating from payphones may be blocked. An intelligent node is provided within the telecommunications network to identify whether a non-toll call originated from a payphone. The intelligent node may apply a number of different criteria to determine whether to block a non-toll call that is determined to have originated from a payphone. The intelligent node may be customized to apply criteria based upon customer request. The customer may also identify additional processing that is to be performed when a call is to be blocked.
