Using enhanced answering machine detection (“AMD”) to detect reassigned numbers

A non-transitory computer readable medium storing instructions that when executed cause at least one or more computer processors in a call handler to:

• originate a first outbound call to a telephone number that is answered whereby a first pre-recorded greeting is detected;
• process the first pre-recorded greeting to derive a first set of greeting meta-data associated with the telephone number;
• originate a second outbound call to the telephone number after originating the first outbound call, wherein the second outbound call is answered;
• detect a second pre-recorded greeting played on the second outbound call;
• process the second pre-recorded greeting to derive a second set of greeting meta-data associated with the telephone number;
• store the second pre-recorded greeting in memory;
• compare the first set of greeting meta-data with the second set of greeting meta-data after determining that a timeframe was exceeded from when the second outbound call was originated after the first outbound call;
• provide a graphical user interface on a computer to an agent in a contact center for facilitating a comparison of the first pre-recorded greeting and the second pre-recorded greeting by the agent after determining that the first set of greeting meta-data is not the same as the second set of greeting meta-data;
• receive an input from the computer by the agent using the graphical user interface indicating the first pre-recorded greeting is different from the second pre-recorded greeting;
• and
• update a call record based on the input from the agent indicating the telephone number is no longer still associated with the individual.

A call handler comprising a computer processor configured to:

• originate a first outbound call to a telephone number wherein the first outbound call is answered;
• detecting a first pre-recorded greeting after the first outbound call is answered;
• process the first pre-recorded greeting to derive a first set of greeting meta-data associated with the telephone number;
• originate a second outbound call to the telephone number after the first outbound call is terminated, whereby a second pre-recorded greeting is detected after the second outbound call is answered;
• process the second pre-recorded greeting to derive a second set of greeting meta-data associated with the telephone number;
• determine a time period was exceeded from when the second outbound call was originated after the first outbound call was originated;
• cause the first set of greeting meta-data to be compared with the second set of greeting meta-data after determining that a timeframe was exceeded from when the second outbound call was originated after the first outbound call;
• provide a graphical user interface on a computer to an agent in a contact center to compare the first pre-recorded greeting and the second pre-recorded after determining that the first pre-recorded greeting is not the same as the second pre-recorded greeting;
• receive an input from the computer wherein the agent uses the graphical user interface to indicate the first pre-recorded greeting is different from the second pre-recorded greeting;
• and
• update a call record based on the input from the agent indicating the telephone number is no longer still associated with an individual identified in the call record.
