Those opt-outs should be changed to opt-ins - it's very hard to

IIRC the law says that it must be "opt-in" not "opt-out".


UK law doesn't apply to other countries so they can still phone
you.

UK law should apply to companies that do business in the UK.


How are you going to enforce UK laws on overseas companies?

If the company does business here then they must have a UK presence,
yes?

No. What kind of business presence does a scammer require in the UK to
carry out scams by phone here?

Therefore fines could be imposed for breaching UK laws.

I can sure a scam outfit in Kolkata will be quaking in its boots. Lets
just hope they are not the kind of naughty people who would not pay a
fine! (assuming you can identify who they are)

One form of direct action you can take here, is to identify the VoIP
operator that is providing call termination services in the UK and get
them to remove or block their accounts. This is something that they tend
to do fairly regularly anyway, since the scammers quite often avoid
paying them, and they are also quite responsive to fraud reports.

However there are hundreds of providers to choose from and the scammers
will just rotate through new ones every so often, making sure they
always have a handful of working services available to use.

I still can't understand why the same principles cannot be applied
that are used for spam filtering. Apart from a blacklist, what about
algorithms to spot suspicious patterns? If CLI number is invalid,
block. If overseas call carries UK CLI, block.

That would prevent a UK operation that chooses to use
an out of country call center from choosing to have those
tho are called by the overseas call center from using a UK
CLI so that anyone who missed the call can call back to
their UK call center.

So? I they want to have the facility for someone to call them
back then they should choose a call centre with a valid CLI.

Not practical. The out of country call centers are much cheaper.

If more that 20 calls
are generated in one minute divert the next call to the operator.

Not feasible with valid out of country call centers that are now so
common.

See above.
