Quick Answer

Potential evidence of a bug or listening device include strange noises on the telephone, changes in the volume during conversation, or person not connected with a situation knowing more than they should.

Tapping a phone line is illegal, but it is still sometimes done for the sake of eavesdropping.

Law enforcement should be contacted immediately when there is suspicion that a phone line is tapped.

Another way that eavesdroppers choose to listen into conversations is by bugging something that will sit in the office. They may send a framed picture, a reusable vase or a small sculpture to the office that they wish to bug. The object is often equipped with small wiring connected to audio devices in order to pick up conversations and send them back to the person who commissioned the gift.
