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.
Claims11
A method for generating a community blacklist comprising:
- receiving, using a processor, an incoming telephone call directed to a recipient telephone number, the recipient telephone number being associated with a telephone service, the recipient telephone number being unassigned to a subscriber of the telephone service;
- determining, using the processor, the incoming telephone call is from an originating telephone number;
- answering, using the processor, the incoming telephone call;
- providing, using the processor, a verbal challenge;
- receiving, using the processor, a response, the response being at least an audible answer;
- measuring, using the processor, a time between when the verbal challenge is provided and when the response is received;
- and
- adding the originating telephone number to the community blacklist based at least on one of the measured time being equal to or greater than a predetermined time and the audible answer corresponding to at least one predetermined answer.
A system for generating a community blacklist comprising:
- a processor;
- and
- a memory coupled to the processor, the memory storing instructions, the instructions being executable by the processor to perform a method comprising:
- receiving an incoming telephone call directed to a recipient telephone number, the recipient telephone number being associated with a telephone service, the recipient telephone number being unassigned to a subscriber of the telephone service;
- determining the incoming telephone call is from an originating telephone number;
- answering the incoming telephone call;
- providing a verbal challenge;
- receiving a response, the response being at least an audible answer;
- measuring a time between when the verbal challenge is provided and when the response is received;
- and
- adding the originating telephone number to the community blacklist based at least on one of the measured time being equal to or greater than a predetermined time and the audible answer corresponding to at least one predetermined answer.
A non-transitory computer-readable storage medium having embodied thereon a program, the program being executable by a processor to perform a method for generating a community blacklist, the method comprising:
- receiving an incoming telephone call directed to a recipient telephone number, the recipient telephone number being associated with a telephone service, the recipient telephone number being unassigned to a subscriber of the telephone service;
- determining the incoming telephone call is from an originating telephone number;
- answering the incoming telephone call;
- providing a verbal challenge;
- receiving a response, the response being at least an audible answer;
- measuring a time between when the verbal challenge is provided and when the response is received;
- and
- adding the originating telephone number to the community blacklist based at least on one of the measured time being equal to or greater than a predetermined time and the audible answer corresponding to at least one predetermined answer.
