Phone Line Harassment Devices


Homebrew your own simple phone line harassment devices, like those sold in "spy shops" for hundreds of dollars.

Phone Line Disabler

Disables a phone line.  Target can't call out and any calling party will receive a busy signal.

[phone_disable]

Phone Ringer Disabler

Prevents a phone from ringing on incoming calls.  Target can still call out but any calling party will receive no answer (unless you pick up the phone accidently).

[ring_disable]

Hold Invader

Allows remote audio to still be passed while the called party thinks they are on hold.

[hold_invader]

Wrong Number Generator

Outputs the DTMF digit '8' after receiving a valid DTMF digit '4', approximately 75% of the time.

[wrong]

Disconnected Number Message Generator

Disables the ringing of the incoming phone, and plays back a "This number has been disconnected..." intercept recording via a voice recorder IC.  You'll need to record your own message.
