Abstract: A method and a system for detecting spam calls are provided to effectively detect spam and unsolicited calls by transmitting a challenge to a caller before call admission, receiving a response from the caller, and analyzing it. Before or after a call is received, a challenge creator(302) creates a challenge(322) containing a random number. The created challenge is inputted to a rendering device(304). The rendering device renders the challenge so that it is impossible for any machine to read the challenge. Then the rendered challenge is transmitted to the caller. The callee waits for a response, embedded in a message body or block(312), from the caller. The response is compared with the challenge or an acceptable response having a different value. If the response is correct, the call is connected as the caller is regarded as a human.
