all of what you say i'm sure is true, but look at what you are saying
from the average joe's perspective- i've never even heard of SS7...
ok, i've just received a junk fax and i have no idea where it came
from... how do "i" find out. the answer is i don't because i don't
have access to the SS7 switching ID? or how to use it, because i have
no idea what AID information is, because i've never heard of a
Strouger exchange? so would you still say that there's "no
difficulty" in tracing junk faxes?
ps. and what in gods name is a pbx? ;)
-------------------------------------------------------------------------
there is a point in every persons life where they become
overqualified at something.
> 21st Century and the later American BlastFax junk faxes were less
traceable than any spam. With spam you always have the IP address of
the SMTP client and. Unless your fax machine does caller-ID, you have
paid your telephone company for caller-ID, and the junk faxer is not
using any of the several tactics that turn off caller-ID (e.g. a PBX),
you will have no idea from where a junk fax comes.
This is not actually the case. The AID information can be retreived
after the fact. its not like the days of the old Strouger exchanges
where you had to get to the relay before the call ended.
Caller-ID blocking does not stop the AID information and the information
is in the SS7 network in any case. there is no difficulty tracing
back junk faxes, even if they come from a pbx which does not have
an outgoing line number, the fax can be traced to the T1 line by
the SS7 switching ID.
Of course you can take Vernon's word over the advice of someone who
has done that type of stuff and whose company is in the SS7 switching
business. It is pretty interesting though that every time someone
menti0ons some form of authentication Vernon comes out with a categorical
statement that is completely untrue. Then he repeats it again and again.
Either this is a theological point for Vernon or he is a troll.
