A telephone system comprising switching circuitry configured for coupling a call to a telephone extension coupled to the system, voice processing circuitry configured for automatically interacting with the call, a microprocessor, a first data bus connected between the microprocessor and the switching circuitry, and a second data bus connected between the microprocessor and the voice processing circuitry.

Telephone system

An information handling system comprises a IP network connecting a hub to a multimedia server and the hub to a data server, and the hub to an IP telephony device that is then coupled to a network device. When a telephone in one local area network within a wide area network has a change in its status, such as going off-hook, a status message will be sent to an associated extension within another local area network connected to the wide area network to thereby cause a status indicator to notify the user at the remote extension that the telephone the first local area network has had a status change.

Shared knowledge in a telephone system

A fraud prevention system and method are provided which utilize communication between an intelligent network platform 14 and a local telecommunications device 10. The local telecommunications device 10 comprises a memory 20 which stores various data values. Intelligent network platform 14 comprises a memory 22 which stores a copy of the values in memory 20. The intelligent network platform 14 randomly generates an address which is transmitted to the local telecommunications device 10. The local telecommunications device 10 retrieves data located at the address and transmits the data to the intelligent network platform 14 as an access string prior to the placement of telephone calls using the intelligent network platform 14. The time and day of the telephone call may also be included in the access string to prevent signals recorded at one time from being used to place telephone calls at another time.
