Abstract

In one method and apparatus for blocking unwanted calls in a callback system, parameters associated with a callback request (e.g., the user device to which the call is to be directed, the IP address from which the request originated or an identifier of the source computer from which the callback request originated, the party from whom the call is requested) are tracked for each call. A decision to automatically block the requested callback is made based on one or more criteria based on a combination of these parameters, which may be a total over a period of time. In a second method, one or both of the parties to the callback is queried as to whether the callback is unwanted and, if so, one or more parameters associated with the request are blacklisted.

Claims

1. A system for processing a request for a call comprising:

a call server connected to a packet switched network;

wherein the call server is configured to perform the steps of;

receiving via the packet switched network a request from a first party for a call from a second party to the first party, the request including information sufficient to identify a device associated with the first party, the request originating from a source computer;

making a determination whether a total number of requests received from the source computer during a period of time exceeds a threshold; and

connecting the first party to the second party or blocking the request based on the determination.

2. The system of claim 1, wherein the call server is further configured to perform the step of:

adding at least one parameter associated with the request to a blacklist.

3. The system of claim 1, wherein a source computer identifier is used to associate requests with a source computer.

4. The system of claim 3, wherein the request includes the source computer identifier.

5. The system of claim 3, wherein the source computer identifier is a unique identifier.

6. The system of claim 3, wherein the source computer identifier is based at least in part on a user agent that depends on an operating system, a browser, and any browser plug-ins or hot fixes installed on the source computer.

7. The system of claim 3, wherein the source computer identifier is associated with a component of the computer.

8. A method for processing a request for a call at a call server coupled to a packet switched network, the method comprising:

receiving via the packet switched network a request from a first party for a call from a second party to the first party, the request including information sufficient to identify a device associated with the first party, the request originating from a source computer;

making a determination whether a total number of requests received from the source computer for a call from the second party during a period of time exceeds a threshold; and

connecting the first party to the second party or blocking the request based on the determination.

9. The method of claim 8, wherein the call server is further configured to perform the step of:

adding at least one parameter associated with the request to a blacklist.

10. The method of claim 8, wherein a source computer identifier is used to associate requests with a source computer.

11. The method of claim 10, wherein the request includes the source computer identifier.

12. The method of claim 10, wherein the source computer identifier is a unique identifier.

13. The method of claim 10, wherein the source computer identifier is based at least in part on a user agent that depends on an operating system, a browser, and any browser plug-ins or hot fixes installed on the source computer.

14. The method of claim 10, wherein the source computer identifier is associated with a component of the computer.

15. A non-transitory computer readable medium having instructions stored thereon that, when executed by a processor, causes the processor to process a request for a call at a call server coupled to a packet switched network, the processing the request comprising:

receiving via the packet switched network a request from a first party for, a call from a second party to the first party, the request including information sufficient to identify a device associated with the first party, the request originating from a source computer;

making a determination whether a total number of requests received from the source computer for a call to the first party during a period of time exceeds a threshold; and

connecting the first party to the second party or blocking the request based on the determination.

16. The computer readable medium of claim 15, wherein the call server is further configured to perform the step of:

adding at least one parameter associated with the request to a blacklist.

17. The computer readable medium of claim 15, wherein a source computer identifier is used to associate requests with a source computer.

18. The computer readable medium of claim 17, wherein the request includes the source computer identifier.

19. The computer readable medium of claim 17, wherein the source computer identifier is a unique identifier.

20. The computer readable medium of claim 17, wherein the source computer identifier is based at least in part on a user agent that depends on an operating system, a browser, and any browser plug-ins or hot fixes installed on the source computer.

21. The computer readable medium of claim 17, wherein the source computer identifier is associated with a component of the computer.
