Abstract
A method for filtering out a spam call includes: transmitting test information to a calling terminal when receiving a call request from the calling terminal; determining whether feedback information corresponding to the test information and generated by the calling terminal in a one-key reply manner is correct; if the feedback information is incorrect, determining the call request as a spam call request, and filtering out the call request. An apparatus, a proxy server and a terminal are further provided, so as to effectively determine whether a call request from a calling terminal is a spam call request initiated by a machine or software, therefore improving the security and accuracy of a test, and reducing the cost as there is no need to install a speech recognition system.
