If you want to call your loved ones, the best solution is to use a sound system. However, in most of the mobile phones, the built-in speaker is not capable of delivering the sound to the phone in a way that it can be heard by the person on the other side of the line. This is the reason why, in most of the cases, the person on the other side of the phone cannot hear what you are saying.

To solve this problem, you can use the Squirrel Calls app. It is designed to call squirrels and to do it with a sound that can be heard by the recipient.
