System and method for enhanced call progress analysis utilizing dual-prong analysis

A system for dual-prong call progress assessment, comprising:

• an auto-dialer comprising at least a first plurality of programming instructions stored in the at least one memory of, and operating on at least one processor of, a computer system, wherein the first plurality of programming instructions, when operating on the at least one processor, cause the computer system to:
• automatically dial a customer phone number;
• establish a call leg and send audio stream data to an optimized call progress assessment service;
• receive an indication of inconclusiveness from the optimized call progress assessment service;
• and
• responsive to the indication of inconclusiveness, process the audio stream data associated with dialed customer phone number to determine a call outcome using default call progress assessment capabilities;
• and
• an optimized call progress assessment service comprising at least a second plurality of programming instructions stored in the at least one memory of, and operating on at least one processor of, the computer system, wherein the second plurality of programming instructions, when operating on the at least one processor, cause the computer system to:
• receive audio stream data associated with the dialed customer phone number via the call leg;
• process the received audio stream data using one or more call progress analysis methods;
• receive the result of the one or more call progress analysis methods;
• determine if the received result is received before a predetermined threshold time period is surpassed;
• determine if the received result has a confidence rating greater than a predetermined confidence threshold;
• wherein if the predetermined threshold time period is not surpassed and the confidence rating is greater than the predetermined confidence threshold, determine a call progress assessment outcome;
• and
• wherein if either predetermined threshold is not satisfied, send the indication of inconclusiveness to the auto-dialer.
