Subject: How secure is POTS?

Hi All:
A friend called me three times yesterday using POTS at their end and my
handy # at my end.
My handy recorded the number that was sent over the telephone line and
placed this number in my "missed calls" box.
This friend (Helen) lives in another city with a different area code.
Calling the number, which is a POTS number that has the same area code
as mine, I get Alan (another friend who lives near me). 
He claims he doesn't know Helen and that the call didn't originate from
his phone.
I have no entry for Alan in my handy data base.

Helen's area code is 02243.
My area code and the area code of Alan is 02241.

I tried calling the number shown in my handy's "missed calls" box
using Helen's area code thinking that the "3" in 02243 was somehow
changed to a "1" but that went nowhere.  The party that answered
was not Helen and they didn't know any Helen.
How Is this possible?  Is there some 'hanky panky' going on here?
Since this is my first experience with such a conundrum, warning bells
went off in my head and I thought it best to ask others about my
experience and what they thought I should do.
Of course the Telephone Co. swears that their system is "idiot proof".
Has anything like this ever happened in the US?
My POTS connection is over DSL and a splitter/router so it is a bit
off the subject of this group. 
So if there objections, I will pack up my tent and go home.

Thomas
