do you care about privacy of your phone conversations? here is nice gadget

Model CX-100 provides complete phone conversation privacy. Protects
from wiretapping, eavesdropping and parents listening in on a another
cordless handset! The eavesdropper will hear total noise/gibberish
while you enjoy a crystal clear telephone conversation. The device
works by scrambling the audio into noise-like sounds and turning it
back into human speech at the other end of the conversation.
Eavesdroppers in the middle are left out of luck.
