Thank you for that link. This is very interesting.

We receive an increasing number of calls from spoofed US numbers in
Switzerland. Mostly tech support scams. I was pondering if there is a
way to validate them via STIR/SHAKEN.

We try to filter out invalid +1 prefixes and lengths, but that is a
rather fuzzy thing to do.

So it would be great, if we could implement STIR/SHAKEN to validate
received calls from the +1 prefix.

Unfortunately to register for a STI-PA account, only TSP with an
address in he United States are allowed. Do you know if there is a way
to register as a Swiss Ofcom registered TSP?

(And yes, I am aware that signature signalling also has to be
implemented but we have to start somewhere).

Hopefully STIR/SHAKEN can in future be deployed on a global level.
Germany and UK would also benefit a lot, seeing also a lot of spoofed
calls with their prefixes.
