Thank you Pat! You've given me insight.
It didn't occur to me that a guest might send faxes over the same phone
line by which the management receives faxes. The number is advertised
as the fax line for Brookstown Inn in Winston-Salem. The building was
erected in 1836 as a textile mill. The inn is a sort of museum.
My relatives say they did stay there once. They think the hotel must
have been trying to fax them travel ads but don't understand why they
dialed the voice number.
That didn't sound right. Annoying people with faxes would discourage
repeat business. Besides, under the law, an established business
relationship does not justify faxing an ad without specific permission.
And if the hotel were faxing a list of former guests, the list the
second day would exclude those who had received their faxes the first
day. So one would not expect the phone to ring at exactly 9 AM both days.
Suppose faxes submitted by hotel guests are cued until normal office
hours. If the fax intended for my relatives was the first in line, that
could be why the phone rang at 9 AM both days.
I couldn't find anyone who knew how it sounds to be called by a fax
machine. So I installed fax software on my computer, faxed my
relatives' voice line, and listened on an extension. I recognized the
beeps. Apparently their answering machine took the beeping for a person
having trouble punching a touchtone code. The machine's voice
instructed the caller to punch the access code, and the answering
machine waited. That explains why for several seconds the machine's
display said it was being remotely accessed.
I can even explain why the voice line was dialed. Daplus.us is an
online phone book that seems to be updated several times a year. For
years, it has listed my relatives' fax number as their voice number.
I suppose someone with a subscription to daplus could request fax
numbers, and daplus would probably give my relatives' voice number as
their fax number.
I think a hotel guest who wanted to fax my relatives got the wrong
number from daplus. The first day, the guest got a report that the fax
hadn't gone through, so the guest submitted it again.
[TELECOM Digest Editor's Note: Then they probably did it a few more
times 'just to make sure of the number', etc. You did not say if the
problem was still going on or not. PAT]
