Is it only in large metropolitan areas where all calls to and from
residential and pay phones are logged, or is this the case in the vast
majority of phone systems?  In Urbana, after receiving numerous calls
which hung up when answered over a period of a few weeks, I called the
telephone company to see what could be done about it.  They told me
that they could not find out what number those calls were made from.
They said the telephone system did not work that way.  They could put
a "tap" on the line which would record what numbers calls to our phone
were made from, and they would then match the log created by this tap
with a log that we would keep of when we received these hangup calls,
and then the police would pursue the matter.  This would have cost us
a fee (~ $20.00 ?).

Our other option was to have our number changed, which they would do
for free if we then made our new number unlisted.  If they had the
capability of looking through their logs to find out where the calls
were originating from, I think that they should have done that.  We
also received several calls for me from some guy that my wife said
sounded like a cowboy, but I was never available when he called, and
he never left a message or called back at the suggested times.  I
would have loved to find out who this guy was and why he was calling
me, as well as if he was the caller who was hanging up or not.  After
a while, the calls stopped on their own.  At the time, our local
telephone system did not have caller ID available, by the way.
Perhaps Caller ID is necessary for the logs to be made.
