1. A method of identifying a call device, the method including operations executed by a processor, the operations comprising:
receiving, by a voice communications computer system (“VCCS”), a ring signal originating from a call device, the call device associated with device identification data;
identifying, by the VCCS, at least one audible frequency component of the ring signal and at least one electronic frequency component of the ring signal;
identifying a device identification characteristic based on the at least one electronic frequency component;
identifying a stored identification characteristic associated with the device identification data;
generating, based on a comparison of the device identification characteristic to the stored identification characteristic, fraud estimation data; and
providing the fraud estimation data to a user interface device configured to communicate with the VCCS.
