Maintaining phone calls safety is incredibly important in our times. The most of unauthorised calls during meetings, is made from cell phones. The only way to prevent being recorded is the usage of cellphone microphone jammer, which is called Safe Box phone. It generates properly selected combination of noises, which disrupts all microphones you can find in mobile phones (PREMIUM-class too).
Work of the phone itself is not disrupted, so it can work properly, when needed. Thanks to Safe Box phone qualities, it becomes an indispensable part of classified meetings.
