Ofcom makes a silent statement on calls

Ofcom the regulator for Communications (and other things) has published a statement on"tackling and handling silent calls".

Now companies are only allowed to make automated calls once per day, unless they are handled by real people. Ofcom has the power to fine any company that abuses this, though it can be difficult to regulate as often silent calls will not have an exposed CLI (caller line identifier) or the call may come from outside the UK.

At least they're making an effort to stop these annoying calls though.
