Abstract

A method for filtering a telephone call is provided. The method may comprise receiving from a caller the telephone call directed to a communication device associated with an intended call recipient. The received telephone call may be scored based on predetermined scoring criteria to create a score indicative of a desirability of the telephone call. Furthermore, the method may comprise comparing the score to a predetermined threshold score. Based on the comparison, the method may further comprise selectively classifying the telephone call as an unwanted telephone call. Furthermore, the method may comprise selectively rejecting the unwanted telephone call.

Claims

1. A method implemented by a computer for filtering a telephone call comprising:

receiving from a caller the telephone call directed to a communication device associated with an intended call recipient, the Internet being disposed between the computer and the communication device;

scoring the telephone call based on predetermined scoring criteria to create a score indicative of a desirability of the telephone call, the predetermined scoring criteria being provided by the intended call recipient, the predetermined scoring criteria including at least one of a time range, day of week, range of days, and time of year;

comparing the score to a predetermined threshold score;

classifying the telephone call as an unwanted telephone call using the comparison; and

selectively rejecting the unwanted telephone call.

2. The method of claim 1 further comprising:

providing a complaint to the National Do Not Call Registry.

3. The method of claim 1 further comprising:

answering the telephone call;

providing a verbal challenge;

receiving a response, the response being at least an audible answer; and

measuring a time between when the verbal challenge is provided and when the response is received, wherein the predetermined scoring criteria further include the measured time.

4. The method of claim 1 further comprising:

adding the caller or a caller communication device to a blacklist using the score.

5. The method of claim 1 further comprising:

getting from the intended call recipient a grading of the telephone call or effectiveness of a screening after the telephone call is completed.

6. The method of claim 1 further comprising:

automatically requiring a call back number to complete the telephone call.

7. The method of claim 1, wherein the predetermined scoring criteria further include at least one of:

whether the caller or a caller communication device are associated with a whitelist, a blacklist, or a graylist, a number of calls made to different phone numbers by the caller, sequence of calls made by the caller, and a call source type.

8. The method of claim 7, wherein the intended call recipient manually adds the caller or caller communication device to the blacklist or the whitelist.

9. The method of claim 1, wherein at least some of the predetermined scoring criteria are provided by the intended call recipient.

10. The method of claim 1, wherein the telephone call is automatically rejected if a caller Identification (ID) associated with the telephone call is blocked or anonymous.

11. A system for filtering a telephone call, the system comprising:

at least one processor; and

a memory coupled to the at least one processor, the memory storing instructions executable by the at least one processor to perform a method comprising;

receiving from a caller the telephone call directed to a communication device associated with an intended call recipient, the Internet being disposed between the at least one processor and the communication device;

scoring the telephone call based on predetermined scoring criteria to create a score indicative of a desirability of the telephone call, the predetermined scoring criteria being provided by the intended call recipient, the predetermined scoring criteria including at least one of a time range, day of week, range of days, and time of year;

comparing the score to a predetermined threshold score;

classifying the telephone call as an unwanted telephone call using the comparison; and

selectively rejecting the unwanted telephone call.

12. The system of claim 11, wherein the method further comprises:

providing a complaint to the National Do Not Call Registry.

13. The system of claim 11, wherein the method further comprises:

answering the telephone call;

providing a verbal challenge;

receiving a response, the response being at least an audible answer; and

measuring a time between when the verbal challenge is provided and when the response is received, wherein the predetermined scoring criteria further include the measured time.

14. The system of claim 11, wherein the method further comprises:

adding the caller or a caller communication device to a blacklist using the score.

15. The system of claim 11, wherein the method further comprises:

getting from the intended call recipient a grading of the telephone call or effectiveness of a screening after the telephone call is completed.

16. The system of claim 11, wherein the method further comprises:

automatically requiring a call back number to complete the telephone call.

17. The system of claim 11, wherein the predetermined scoring criteria further include at least one of:

whether the caller or a caller communication device are associated with a whitelist, a blacklist, or a graylist, a number of calls made to different phone numbers by the caller, sequence of calls made by the caller, and a call source type.

18. The system of claim 17, wherein the intended call recipient manually adds the caller or caller communication device to the blacklist or the whitelist.

19. The system of claim 11, wherein at least some of the predetermined scoring criteria are provided by the intended call recipient.

20. The system of claim 11, wherein the telephone call is automatically rejected if a caller Identification (ID) associated with the telephone call is blocked or anonymous.
