This is a service that runs $1.99 per month.

How does it work?

For landlines ( you must have the “conference call” or “three way calling” service)

Answer the call and say hello as usual. Then say something to have them wait on hold. They are accustomed to the “endless hold” prank so it’s not likely they will wait very long. Your mileage will vary. So say something convincing so they’ll hold for a moment (e.g. “hold on, my husband is right here and is very interested in your offer!”).

Press “Flash” or just flash the hookswitch like call-waiting. This will take several seconds and the caller/telemarketer will not hear anything.

Dial your favorite robot (see the ‘Our Robots” page). Depending upon your phone company, you may be able to immediately press flash again. Some carriers will require the second leg to actually connect first. But my robot doesn’t ring so you should hear “hello?” quickly. Also, some VoIP carriers will connect faster if you put a # at the end. You should practice this procedure before you have a telemarketer!

Press MUTE on your phone. If you don’t have a mute button then stay quiet. Any background noise will affect the robot. If you have it, press SPEAKER so you can set the phone down and continue with your life.

If you want an easier way to do this, consider a “Summon a Pirate” subscription (click here)

For mobile phones (iPhone/Android):

Press “add call”

Dial your favorite robot (see the ‘Our Robots” page). While you’re dialing, keep chatting into your phone like you’re trying to get Mr. Jones (“yeah – phone for you”, “okay, he’s coming hang on…”, etc)

Press “Add call” or “Merge call” or “Conference” or whatever will add the robot to the conversation.

MUTE YOURSELF so your background noise doesn’t affect the conversation.

Listen to the call, and hang up when the telemarketer hangs up.
