Regulatory requirements on Caller ID CLID

thrifty_pete

I'm a BT customer and receive calls which have invalid numbers on caller ID. Do I have a case to complain under the Ofcom rules? According to the Consolidated General Conditions:
https://www.ofcom.org.uk/__data/assets/pdf_file/0021/112692/Consolidated-General-Conditions.pdf
“Invalid and non-diallable CLI
C6.6 Where technically feasible, Regulated Providers must:
(a) take all reasonable steps to identify calls, other than calls to Emergency Organisations,
in relation to which invalid or non-diallable CLI Data is provided; and
(b) prevent those calls from being connected to the called party, where such calls are
Identified”
Do BT just get out of this by saying the customer has to block them manually using Call Protect or that is it not technically feasible to block them? Given the BT phone network knows that the number is not valid when I try to dial it, presumably it could be done when the call enters the BT network?

I'd agree with your interpretation of the General Conditions, but there doesn't seem to be much urgency to comply with it amongst the phone companies.

Of course, if it does start being aggressively enforced there's one very obvious possible negative consequence: scammers will stop presenting invalid or undiallable numbers and instead move on to showing numbers that are genuine and diallable but belong to other people.

If you're particularly interested in the matter, Ofcom are consulting about it at the moment:
