Disclosed is a secure telephone call management system for authenticating users of a telephone system in an institutional facility. Authentication of the users is accomplished by using a personal identification number, preferably in conjunction with speaker independent voice recognition and speaker dependent voice identification. When a user first enters the system, the user speaks his or her name which is used as a sample voice print. During each subsequent use of the system, the user is required to speak his or her name. Voice identification software is used to verify that the provided speech matches the sample voice print. The secure system includes accounting software to limit access based on funds in a user's account or other related limitations. Management software implements widespread or local changes to the system and can modify or set any number of user account parameters.

An audio information delivery system collects electronic data via Internet or other conveyance, and responsive to customer inquiries, selectively retrieves data from local stores in areas of interest to the inquiring customers, formats the data, and transmits the data in audio form to the customers via their telephones. Initially, an information delivery agency makes advance arrangements with remotely located content providers to repeatedly obtain information of prescribed character. Agency computers continually gather digitally stored audio and text information from the predefined content providers and assemble the gathered information into a universal database. Separately, the agency enrolls a number of individual customers, which includes obtaining each customer's preferences regarding information content and playback order. Responsive to a telephone call from a registered customer, agency's computers retrieve the caller's pre-stored preferences and proceed to identify information in the universal database that pertains to the caller's subject matter preferences. After preparing vocalizations of the text information, agency computer equipment audibly presents the audio information and vocalizations to the caller in predetermined order via the caller's telephone connection. This is achieved, for example, by using an intermediate telephone network such as a wireless carrier network.

A secure telephone call management system is provided for authenticating users of a telephone system in an institutional facility. Authentication of the users of the telephone call management system is accomplished by using a personal identification number, biometric means, and / or radio frequency means. The secure telephone call management system includes accounting software capable of limiting access to the system based on funds in a user's account, and includes management software capable of implementing widespread or local changes to the system. The system monitors a conversation in the telephone call to detect a presence of a first characteristic in audio of the conversation, and terminates the telephone call if the first characteristic does not match a second characteristic of biometric information of a user or a called party.

A hybrid coaxial cable network employing interdiction to ensure privacy in telephony communications. The video and telephony signals are secured such that telephony and interactive video signals to and from a subscriber do not appear on the network at any other undesired subscriber location.

A hybrid telephony system with packet switching as well as circuit switching optimizes utilization of transport networks, and is accessible from any conventional telephone set. A call originating from a circuit-switched network is passed through a gateway computer to a backbone packet-switched network, and then through a second gateway computer to a second circuit-switched network where it terminates. The voice of both the originating party and the terminating party is converted to data packets by the near-end gateway computer and then converted back to voice by the far-end gateway computer. In an alternative scenario, the originating party uses a computer on the packet-switched network, which replaces the originating circuit-switched network and the originating computer. Powered by CPUs, DSPs, ASICs disks, telephony interfaces, and packet network interfaces, the gateway computers may have media conversion modules, speech processing modules and routing resolution modules, and are capable of translating telephony call signaling as well as voice between circuit-switched and packet-switched networks. Optionally, the gateway computers may also have analog trunking modules, MF and DTMF digit modules and special services modules, in order to support analog circuit-switched networks and secure telephone calls.

A method and system for a secure telephone protocol are disclosed, which can be implemented using current Voice over IP (VoIP) protocols, Session Initiation Protocol (SIP, as specified in the Request for Comment (RFC) 3261 from the Internet Engineering Task Force (IETF)), Real Time Transport Protocol (RTP, as specified in RFC 3550), and Secure RTP (SRTP, as specified in RFC 3711).

A telephone security device is built into a telephone unit. The device includes a sensor to detect an intrusion into the area in which the telephone is located. Upon detection of an event, the device places the telephone off hook, and triggers the redial feature of the telephone. This causes the telephone to redial the last number that had been called. The telephone then remains in the off hook condition for a delay interval to allow the recipient of the call to listen, via the telephone, for any sounds indication that an actual intrusion has occurred. In order to arm the security device, the user simply dials the number that is the intended recipient of the call, hang up, and switch on the sensor. Detection of a security event will then cause the last dialed number to be redialed.
