Hi - The signal from the telephone base to the cordless handset of the VTech IS8151-5 is encrypted. Thank you, -VTech Support
Sorry, there was a problem. Please try again later.I'm not sure about the handset being encrypted. That would be a question for the manufacturer. I will say that I'm not 100 percent happy with the product on the communication side. Your voice comes across like you're in a tunnel to the other party. I won't buy this product again.
