Abstract
A method of detecting robocalls includes generating at least one of an identification (ID) spoofing score, a number similarity score, and a call length prediction request for a telephone call request. The method further includes generating a robocall predictor score based at least in part on the call length prediction score and the ID spoofing score, and rejecting the telephone call request when the robocall predictor score indicates the telephone call request is invalid.
