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.

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). The secure telephone protocol can include a shared secret value that is cached and then re-used later to authenticate a long series of session keys to be used for numerous separate secure phone calls over a long period of time, thereby providing cryptographic key continuity without the need for voice authentication. In an embodiment, the secure telephone protocol can utilize the Diffie-Hellman key exchange during call setup, and AES for encrypting the voice stream.

An MAC address of each of devices under testing is entered. An IP address is assigned to each entered MAC address. The IP addresses and telephone numbers assigned to the devices and a failure test terminal are associated with one another and registered in a system server. Out of telephones connected to the devices, sets of two telephones are determined. For each set, a call is made from a first telephone connected to the device to a second telephone connected to another device. When the communication is established, a call is made from the called second telephone to the first telephone. If the communication is not established, communication with a telephone connected to the failure test terminal is tried. Thereby, adequate test on a large number of devices with simple operation is possible in performing an operation test on a VoIP device.

The invention relates to a quantum secrete telephone, which combines the quantum secrete communication with the current telephone communication and realizes secure telephone communication by encrypting/decrypting voice by use of an absolutely secure quantum codebook; the best advantage of the system is: by using FPGA as the control core, as the FPGA does not open the interface of the storage chip of the codebook, any behavior trying to attack a terminal so as to steal the codebook remotely is invalid.

A telephone using conventional telephone mechanical and electrical components mounted within a telephone housing, typically mounted on a wall, with the earpiece and mouthpiece mounted to be protected by the telephone housing. The housing has a front face surrounded by tapered edges, which provide angled transitions from the front face to the mounting surface. To operate, the user pushes an on/off switch and places an ear next to the fixed earpiece. The telephone is designed for use in prisons, so inmates within a prison cannot hang themselves with a handset cord or break a handset and handset cord off for use as a weapon. The tapered edges restrict access to the abrupt sides of the rigid housing, so the phone does not protrude as a blunt object from the wall. The telephone, which may include a payphone escrow system, is also suitable for use in any high crime or remote public areas to reduce the potential for vandalism. The telephone design reduces the cost of maintenance by eliminating the need to fix and replace a telephone handset, or damaged housings.

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.
