   If a person who knows what they are doing puts a tap on your phone you
won't be able to detect it.  If you are willing to spend some money your best
bet is to buy a scrambler.  This will convert your message into a digital 
format which is almost impossible to decode.  The only downside to this is 
that both parties must have them but they make any bugs on your line useless.
You can even get portable scrablers that work with car phones.
