PrankOwl

Returning to free prank call sites, PrankOwl is worth a try. This website functions similarly to the others, but it has a few characteristics that set it apart from the pack.

You may specify a time restriction for the call here. When the timer expires, the call is automatically terminated. The remaining features are standard; your phone number will not be recognized, you can use pre-recorded calls, and so on. You can use this to send pre-recorded voices and make prank calls all across the world.

To unlock more advanced capabilities, such as calling from another country or displaying a custom name on the receiver's smartphone screen, you must purchase tokens.
