The federal law in 47 USC 227(e) says:
(1)In general
It shall be unlawful for any person within the United States, or any person
outside the United States if the recipient is within the United States, in
connection with any voice service or text messaging service, to cause any
caller identification service to knowingly transmit misleading or inaccurate
caller identification information with the intent to defraud, cause harm, or
wrongfully obtain anything of value, unless such transmission is exempted
pursuant to paragraph (3)(B).
In (3)(B) is a narrow carve-out for law enforcement and court orders.
The important point is that spoofing is illegal with fraudulent intent, OK with
benign intent.
This is a very interesting conversation as there is a ongoing discussion on how
to ban spoofed calls here in Italy..
Here operators must identify each customer and ensure that they are screening
incoming numbers.
I assume by "incoming" you mean incoming from the customer? That is,
you're making sure your customers are not spoofing?
Most do, but some do not and become sources of spoofed traffic.
The biggest problem however comes from out of country originators that allow
foreign call centers to use Italian numbers.
Are these spoofed or are they actually allocated to them? If they are
actually allocated, their upstream provider should be enforcing too, right?
Thus the calls come in from an international carrier.
We are moving twords blocking incoming calls from international trunks
containing Italian from numbers, something we see already in place for carriers
in other EU countries such as France.
On the other hand, this makes your "incoming" above sound like incoming
from the phone network. So I'm probably confused.
Most operators here have been against stir/shaken as a means to resolve the
problems.
What reasons?
