FAQ: Blocking Auto Dialer Calls

Auto dialer calls typically have a brief pause (1-2 seconds) after you answer before a person or recording begins speaking. This happens because the auto dialer is connecting the call to an agent or playing a recording after detecting that someone answered. Other signs include pre-recorded messages, calls from similar number patterns, and requests to press buttons to continue or opt out of future calls.
