Abstract

A Call Alerting and Control System is provided in a communication environment to allow an Internet user (“user”) approximately real-time monitoring of information about an incoming call from a calling party while maintaining a connection with the Internet. The monitored information can include the calling party'"'"'s name and telephone number. The system could also allow the user to provide an answering machine-type message to the calling party and the user to listen to the calling party'"'"'s response to the message while still connected to the Internet. The system can further allow the user to reroute, answer or otherwise treat the incoming call while, at the user'"'"'s discretion, either maintaining or disconnecting a connection to the Internet.

Claims

1. A method for managing incoming calls from a calling party to a communication line of a user, where the user can be connected to a packet-based data network, the method comprising:

receiving an incoming call via a telephone network, wherein the telephone network includes a service control point, a service switching point and a gateway system;

determining with information from the gateway system whether the user is connected to the packet-based data network;

if the user is connected to the packet-based data network, prompting the user to choose at least one call handling option, where the call handling option includes rerouting the incoming call to an alternate communication line, wherein the alternate communication line differs from a communication line of the incoming call,

allowing a one-way voice connection to be established by the service switching point to the user to allow the user to listen to the calling party contemporaneous with the calling party leaving a message and while the user maintains a connection with the packet-based data network, without answering the incoming call; and

thereafter, allowing a two-way voice connection to be established with the user via the service switching point if the user chooses to answer the incoming call.

2. The method of claim 1 where the call handling option includes automatically treating the incoming call in accordance with an identity of the calling party.

3. The method of claim 2 where treating the incoming call further includes sending the incoming call to a voice messaging server.

4. The method of claim 3 where treating the incoming call further includes disconnecting the incoming call.

5. The method of claim 2 where the call handling option includes answering the incoming call.

6. The method of claim 5 where answering the incoming call includes connecting the calling party to the user over the packet-based data network via a two-way Voice Over Internet Protocol (VoIP).

7. The method of claim 5 where answering the incoming call further includes:

disconnecting the packet-based data network connection; and

connecting the calling party to the user via a switched voice connection.

8. The method of claim 1 further including processing the incoming call before notifying the user.

9. The method of claim 8 where the processing includes automatically rerouting the incoming call to an alternate communication line in accordance with an identity of the calling party.

10. The method of claim 8 where the processing includes automatically connecting the incoming call to the user in accordance with an identity of the calling party.

11. A call alerting and control system for managing incoming calls from a calling party to a communication line of a user, where the user can be connected to a packet-based data network, the system comprising:

a Client System operable to notify the user of an incoming call;

a Telephone Network, wherein the Telephone Network includes a Service Control Point, a Service Switching point and a Gateway System;

wherein the Client System is able to prompt the user to choose at least one call handling option after the Gateway System receives the incoming call, where the call handling option includes rerouting the incoming call to an alternate communication line, wherein the alternate communication line differs from a communication line of the incoming call; and

wherein the Gateway System is able to establish a one-way voice path from the calling party to the Client System through a data network connection, which allows the user to listen to the calling party leaving a message while the user maintains a connection to the packet-based data network; and

further wherein the gateway System processes the incoming call before notifying the user, to automatically reroute the incoming call to said alternate communication line or connect the incoming call to the user in accordance with an identity of the calling party.

12. The system of claim 11 wherein the Gateway System and the Client System manage the incoming call in accordance with a user selected call handling option or after a timeout period for the user to handle the call has elapsed.

13. The system of claim 11 where the call handling option includes the option to treat the incoming call.

14. The system of claim 11 where the call handling option includes the option of listening to the calling party leave a message while the user maintains a connection with the packet-based data network.

15. The system of claim 11 where the call handling option includes the option to answer the incoming call.

16. The system of claim 15 where, when the user chooses the option to answer the incoming call, the Gateway System disconnects the data network connection and connects the calling party to the user via a switched voice connection on the system.
