System and method for scan-dialing telephone numbers and classifying equipment connected to telephone lines associated therewith

Abstract

A telephone scan-dialing arrangement includes a listener module, at least one dialing control module and at least one dialing module, each dialing module being associated with a respective modem. The listener module receives a command to initiate a scan-dialing operation in connection with a profile that identifies, inter alia, telephone numbers to be dialed and operations to be performed during each call and telephone number selection criteria, and provides the identification of the profile to the dialing control module The dialing control module obtains from the profile a set of telephone numbers to be used during the scan-dialing operation and provides the obtained telephone numbers to respective ones of the dialer modules to be dialed for a call, along with information identifying operations to be performed during the call, as each dialer module finishes its previous call. During each call, each dialer module controls its associated modem to dial the telephone number provided thereto by the dialing control module and perform the specified operations. Each dialer module stores call result information in the profile based on results of the call. During each call the telephone scan-dialing arrangement can determine, if the call is answered, the dialer module can determine characteristics of equipment connected to the called telephone line, including whether the equipment is a voice answering equipment, such as a voice telephone or an automated voice answering system, a fax receiving device or a computer. If the answering equipment is an automated voice answering device or a computer, the telephone scan dialing arrangement can also attempt to penetrate the device or computer to determine the operating system and user name/password combination used to access the device or computer. The a profile is stored in the form of SQL (structured query language) database, and the telephone scan-dialing arrangement can generate reports from the call result information in the profile using templates in HTML, RTF or other convenient format.
