[comp.dcom.telecom] Those Beeps _Are_ a FAX Machine Trying to Call

The sound you describe is the CCITT standard sound for "the device
calling you is an autodialer."  FAX machines generate this sound when
making calls.  They do not generate this sound when answering calls.

Patrick is correct to point out that the phone company is required to
help you find the source of an annoyance call -- at no charge.  But
your own idea above (except for the harrassment part which followed)
is a good idea.

Since these calls come at a specific time, if you have call
forwarding, you could make arrangements with one of those P.O.Box/FAX
drops (or anyone with a FAX machine) for you to forward your calls to
their machine from 10:20 to 10:35 some night to receive the FAX and
find the originator.
