Scherzi telefonici Zoo is an Android application that allows you to play funny phone pranks on your friends. The app lets you choose from a variety of voices, including Lino Banfi, Adriano Celentano, Carlo Verdone, and more, to make prank calls like the ones heard on the Italian radio show "Lo Zoo di 105." You can also choose from many phrases from Sergeant Hartman, Renato Pozzetto, and Paolo Bonolis. The app is free to download and use.

It is important to note that due to technical limitations of mobile devices, you cannot hear the audio during the call from the same phone where the app is installed. Therefore, it is recommended to use another phone, call anonymously with #31#phonenumber, put it on speaker, and then use the app to play the prank.
