I have recently been receiving various sorts of threatening calls from an anonymous person. I reported it to the police, and they offered to put a tap on the phone, etc. But I am wondering about the possibilites. One of my friends tells me she used to get regular calls from someone where nothing was said, and the person then hung up. New England Telephone registered her line in some sort of "capture" system. After she got one of these calls, she was supposed to call an 800 number immediately, and the origination of the previous call would be recorded. She had to sign some sort of agreement stating that she would press charges against the caller once he or she was identified. My friend was told that the length of the call did not matter, this would all be done automatically. Is this possible, and how? Only in special exchanges? (Apparently the caller was never identified or else New England Tel did not choose to communicate this information to my friend.) In my own case, what are the possibilities? How difficult would it be for the phone company to identify callers? Would it make a difference what sort of exchange the call originated from? Would it make a difference whether the call originated locally or from a long distance carrier, and would it make a difference which long distance carrier it was? As you can see, I am rather naive about the capabilities of the phone company. In the movies, the police always try to keep the ransom-demanders on the phone for enough time that they can physically trace the calls I guess, but is this now unnecessary? I'd be grateful for relatively non-technical enlightenment. Bruce Waldman, bw@harvarda.bitnet waldman2@husc4.harvard.edu ...!harvard!husc4!waldman2
