Abstract: System and method for putting control of incoming telephone calls in the han ds 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 t he 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 emplo ys a central server in which all of the required intelligence is resident. Audi o signals are exchanged via non-data channels provided by the telephone companies and by the Internet. Either a very simple Internet busy pick-up is provided, or a very complex messaging system is provided, as desired. A feature is the monitoring and screening of incoming calls before deciding ho w to handle them. Another feature is the capturing and storage of the decision making profile.

Abstract: The present invention is related to methods and systems for reducing or canceling echoes during fax communications In an embodiment, during a fax call, a first fax signal from a first fax device intended for a second fax device is detected. Based at least in part on detecting the first fax signal from the first fax device (200) or on the termination of the first fax signa l, an echo audio packet is muted, wherein the echo audio packet is at least partly the result of the first fax signal being transmitted over a network, the network including at least a data network (203).

Abstract: The present invention provides flexible, user-definable call screening processes. The user (112) can optionally define to which telecommunication terminals a screened call is to be broadcast to and under what conditions. A n incoming call is forwarded to a call management system (124) that asks the caller (102) to leave a voice message. The call management system (124) selectively couples the call to a POTS line or a VoIP-capable device (110) s o that the user (112) can listen to the incoming message and thereby screen th e incoming call. Based on the screening, the user (112) can instruct the call management system (124) to connect the caller (102) to the user (112).

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 (126) over a first telephone line (120) via a first computer terminal (110) is detected, wherein the subscriber also has a first telephone station connected (108) to the first line (120). When a caller calls the first line (120) and the first line is busy (120), the call is forwarded to a second telephone line (134) associated with a call manager system (124). The call manager system (124) determines when the subscriber is no longer accessing the computer network (126). At least partly in response to determining that the subscriber is no longer accessing the computer network (126), the call manager system (124) transmits a text message to the caller, the message including the subscriber's phone number. The caller can then call back the first line (120) using the transmitted phone number.
