  • Patent number: 6898275
    Abstract: System and method for putting control of incoming telephone calls in the hands of subscribers with the aid of computer software and the Internet. In effect, a very efficient multiplexer is provided that does not require a change in the behavior of the called party or the calling party. This system permits the called party to hear a spoken message by the calling party in real time, and the content of the spoken message permits the called party to decide how to handle the call. The system adaptively learns and captures the rules of the called party for handling calls, and learns which callers the called party always wishes to talk to. The system uses special control software on the called party's computer which is connected to the Internet. The system employs a central server in which all of the required intelligence is resident. Audio signals are exchanged via non-data channels provided by the telephone companies and by the Internet.

  • Patent number: 6879677
    Abstract: The present invention is directed to processing calls to busy telecommunications lines. In one embodiment, the presence of a subscriber accessing a computer network over a first telephone line via a first computer terminal is detected, wherein the subscriber also has a first telephone station connected to the first line. When a caller calls the first line and the first line is busy, the call is forwarded to a second telephone line associated with a call manager system. The call manager system determines when the subscriber is no longer accessing the computer network. At least partly in response to determining that the subscriber is no longer accessing the computer network, the call manager system transmits a text message to the caller, the message including the subscriber's phone number. The caller can then call back the first line using the transmitted phone number.

  • Patent number: 6738461
    Abstract: The present invention provides a call-return process and system, wherein a called party can return a missed call to a caller's private number. A forwarded call is received by a call management system, wherein the forwarded call was originally directed by a caller to a first telephone line associated with a user. The call management system receives call signaling information, including a phone number, associated with the caller. The call management system then determines whether the phone number is a private phone number or a public phone number. If the phone number is private, the call management system notifies the user of the call, and without revealing the caller's phone number to the user, enables the user to return the caller's call.
