The system then waits to 'hear' any key pressed on the other end of the line. This tells the system that a human answered the call. If the systems hears a key pressed it will stop calling numbers and turn on the speakerphone. If the system does not hear a key pressed it will hang up and call the next number in sequence. We suggest that you have 911 programmed as the 3rd number to ensure that someone is contacted in the event of an emergency (this is totally optional). Note: This system works with most Cable/Internet/VOIP systems and normal phone lines. Note: When recording your message place the microphone close to your mouth for clear recording. Uses Normal Phone Line, with Optional Bluetooth Adapter (sold separately) Can also use Cell Phone (requires Optional Adapter)
