Secure LAN/internet telephony

摘要

A system and method for providing telephony communication through a packet switched data network such as the Internet and an organization having telephone and computer terminals connected to a local area network. Selectable security is provided for the telephony applications through the use of an access gateway between the local area network and the packet switched data network operating in conjunction with an intelligent control network in a public switched telephone network. The access gateway includes storage and a processor for storing security data and running selectable applications based on pre-conditions established for the telephone terminals. Information is obtained from a party seeking to connect to a telephone terminal connected to the local area network both by dialing and by voice prompt and voice recognition dialog.
