A PRANK SOUNDBOARD DURING THE CALL
Laugh track, clap, kiss, slap, fart, boing, horn, rimshot and doorbell. The other person hears them live.

BUILT FOR FUN, NOT HARM

• Anyone can ask us to block their number from receiving Callmeleon calls.
• Emergency numbers (911), N11, toll-free and premium numbers can't be dialed.
