> Where is area code 390? Someone whose caller ID data says


It's an out-and-out SCAM which is violting the Do-Not-Call Act.

There is NO area code 390 in the North American network. I also
doubt that this call is coming in from Italy, which is Country
Code +39.

In North America, ALL three-digit area code combinations with a
'9' in the middle digit are RESERVED for use in a future expansion
to a "longer-than-ten-digit" North American number. Thus there is
NO three-digit area code 390, nor any other N9X format three-digit
area code, at least not at this time.

Therefore, this is some obvious $CAM/$CUM trying to evade any
regulatory action against unsolicited calls.

Would the phoneco's Call Trace (1157) yield any better information?

At least they've settled on a specific fake caller ID number, then...

I can't find any official listing of area code 390, but I did find this:
http://www.yqcomputer.com/
which led me to think it might be a new one.

Don't worry, we have ways of making them tell us who they are, if they call
back...

***** Moderator's Note *****

The number given on that web site goes to the intercept operator here,
so it's a typo. A Google search for "Area Code 390" turned up over
2,000 hits, but the first page was all about telemarketers, so it's
likely that this is a well-known problem.

What I'd like to know is 'How are they spoofing the CID'? If they're
simply resending CID data after the call is answered, I'm not sure
what could be done about that. OTOH, if they're using PRI lines and
misreporting to the IEC, then that's probably actionable.

> ***** Moderator's Note *****

A while back I got a call with my own number as the CID, it was a
telemarketer, I have no idea how they did it other then they were behind
a system that allowed setting the number to what was supposed to be the
primary number, I told them I was on the DNC list and not call me again,
nothing since.

With luck the call trace will use the ANI, I was never on the
maintenance end and can't remember how it worked.

>> I can't find any official listing of area code 390, but I did find this:

Nope. All N9X area codes are reserved for the transition to longer
numbers. There is no A/C 390 and never will be.


All landline numbers in Italy start with +390. The Vatican has regular
Rome numbers which start with +3906.

This is a multi-part message in MIME format.





There is no area code 390 in North America. Codes with a middle digit of 9 are not permitted.

It could be a fraudulent number, as Bill Horne noted.

But it could also be an international number. Many caller ID display phones, or the central office switches that drive them, cannot handle the 15 digits that might come from an international number. They truncate it and just display the first 10, or the the last 10, digits. To add to the confusion, the + sign is also not displayed.

Viewed as an international number, this would be a truncated piece of a number in the city of Modena, Italy. Parse it as +39 059 991 48xx.

I have no idea how it's done, but there was an article (sorry, I
forgot where) about an 800 service that would spoof the caller-ID "as
a joke".

I always thought caller-ID came out of the ANI, but apparently not. I
have no idea of where it comes from or how it is transmitted. Maybe
someone could explain it in layman's terms.


[Historically, the Bell System was slow in adopting in ANI.
Originally DDD didn't have it. Though crude ANI was developed for
suburban toll calls in the 1940s, as late as 1972 a big city downtown
Centrex was still using ONI (operator requested calling number), even
for suburban message unit calls. I'm not sure if No. 5 crossbar was
initially designed with ANI or not. ]

I'm suprised it worked. That company is already in
violation of FTC regulations. FTC regs require them to
provide their own phone number on caller-ID. Ref:

> I'm suprised it worked. hat company is already in >> violation of FTC regulations.
I respectfully suggest that being in violation of FTC regulations
means nothing.

Recently I spoke to a friend who was bothered by a telemarketer who
violated numerous FTC regulations (like calling outside the designated
time frame, disregarding do not call, etc.) My friend duly logged the
calls and made a formal complaint.

Nothing was done.

As mentioned earlier, it really appears the telephone company and
regulatory authorities take no action unless there is a high volume of
complaints. (They don't deal with Call Trace until there is a volume
of calls of a *** threat). When cases make the newspaper of a
telemarketer fined for violating the rules, the violations were in the
_thousands_ of calls.

Is anyone aware and can describe where a single complaint by an
individual got action?

If the caller is behind a private telephone switch, some switches
include user-programmable Caller ID. If it were ANI, the line number of
the outgoing trunk would show up in the display of the called party.

If the caller's extension can be reached as direct inward dial and the
switch is programmed to display the extension as a dialable 10-digit
telephone number on outbound calls, then user-programmable Caller ID can
be used to give useful information. If one is trying to return a call,
knowing the outbound trunk he used isn't helpful.

Sometimes user-programmable Caller ID has a benign purpose.

CLID is supposed to be completely separate from ANI, and is
transported as part of SS#7 messages. ANI is for billing, CLID is for
who's calling.

In a PBX, the ANI can always be the main number since that's where the
calls are billed, while the CLID should identify the extension.

John

That doesn't sound correct since ANI shouldn't originate at a PBX. ANI
should be the outgoing trunk. If ANI could originate at the PBX, if the
subscriber screwed with it the telephone company wouldn't be able to
bill properly.

Please don't Cc me.
