Anybody can clip onto phone wires. Use a cell phone instead. |

Ok this might work Get a phone plug and strip the wires on the end of it plug the other end of the plug in to your phone socket then waring gloves jam the other end with the striped wiers in to a ac outlet then switch it on... that should stop just about any thing LOL be carfull but phone lines can give you a nice shock alone, and ac power will kill you.

o.o
Jord, that would destroy the switching equipment on the telephone poles and incur the wrath of the telecom companies. |

Normally for the phone to get connected to telephone office, a impedance has to be applied between the two wires that reach your home. When ever any body connects a phone to the Cable, a Drop in voltage will be observed in the local loop. You might be able to make use of the drop in voltage to detect whether anybody is hooking a phone into your line. This way you should be able to detect that somebody has looped the line. |

Somebody could connect a capacitor-coupled audio amplifier or recorder to your phone line. It won't draw any current so you won't measure a DC voltage drop. |

Could be done inductively as well. An inductor with a lot of windings connected to a high impedance amp will be virtually impossible to detect. |

But these methods will not load the Telephone office equipment and the loop would not be established. For a call to be made, there should be 600 Ohm Impedance for 2 Wire communication (ideally) between the pair. Once this impedence is connected, there will be a voltage drop which in turn sets up the local loop.. This is my understanding.. Is my understanding Wrong |

Hi Renjan, Your phone draws DC current to establish a call. Then a tap can be another phone which draws more current which can be detected, or a tap can be capacitive-coupled or inductive-coupled that does not draw DC current and if it has a high impedance so the level is not changed then it can't be detected. |

I say you learn a sophisticated code and teach it too all your family and friends, no more worries! Or, this is illegal, but cant you make a radio jammer, if its in your house? I don't know, Wait theres always look for the god damn thing :P or as audioguru suggested use a cellphone.

Opps !! Now i realize that the discussion is all about eavesdropping. I am sorry for creating the confusion. |
