I use to prank the telemarketers but unable to with robo callers. One a woman called wanting me to switch long distance carriers. I halfway listened to her spill for twenty minutes while watching TV. Finally she wanted me to switch. Told her I couldn't for I was house sitting. She asked about my home number. Told her I only had a beeper. She asked me why I let her talk so long. Told her she had such a lovely voice and I enjoyed listening to it. She slammed the phone down on me.
