Inthe Allies developed a voice encryption system called SIGSALY which used a vocoder to digitize speech, then encrypted the speech with one-time pad and encoded the digital data as tones using frequency shift keying.

However, the FCC's seminal Carterfone Decision ofthe FCC concluded that electronic devices could be connected to the telephone system as long as Billion ROCKWELL V90 K56 MODEM used an acoustic coupler. Since most handsets were supplied by Western Electric and thus of a standard design, acoustic couplers were relatively easy to build.
An even lower-cost option was the Pennywhistle modemdesigned to be built using parts from electronics scrap and surplus stores. Like the A, it used different frequency bands for transmit and receive.

It was similar in design, but used the lower frequency set for transmission. According to Vadic, the change in frequency assignments made the intentionally incompatible with acoustic coupling, thereby locking out many potential modem manufacturers. The Hush-a-Phone decision applied only to mechanical connections, but the Carterfone decision ofled to the FCC [ who? Raspberry Pi 3.
