- Take the cellphone and put the settings on to "Auto Answer". Auto answer is when someone calls the number and it automatically answers the phone or connects the call (no rings involved).Plug it into a charger near the area where the conversation is going to happen.Plug the headphones in
- so if you make a noise
- it will be a tiny/very unnoticed noise.Hide the phone somewhere
- for example
- plants or behind a cabinet.Leave the room and act normal. If you have a suspicious expression on your face
- then people may think something is going on.Call the phone either immediately after you leave or at the time of the event.Listen to the conversation.
