摘要：
A device receives, from a user device, a call destined for a call center, and provides an audio CAPTCHA (Completely Automated Public Turing test to Tell Computer and Humans Apart) to the user device in response to the call. The device also receives, from the user device, a response to the audio CAPTCHA, and determines whether the response is correct. The device forwards the call to the call center when the response is correct, and drops the call when the response is incorrect.
