But not if recipient is an 0800 FreeCall.

Not limited to free (to caller) calls (0800, 0808 and possibly even 0500 - though I don't know if C+W pass CLI). Pretty much any redirection service might pass the number.

I rent a number of 03xxx and some geographic numbers in different cities (as well as some 0800s), and the control panel allows me to capture CLI, and for that matter, record all calls (with no bleeping tones).

Thought you said earlier that Withheld #s don't show.

Strowger relay, now there is something to behold - I used to work in Wren House, next door to Faraday House, connecting calls to places far and beyond, and tother side of't world, ma kin are from Greenock.

Agreed, that's typical British thinking in action, they don't look at the bigger picture, and won't invest for future returns, unfortunately, I'm getting to the age now when this is all irrelevant.

there's something at the back of my mind about not passing CLI to 0800 numbers used by Childline, Samaritans, etc. But it's possible I imagined it.

Well, I presume they can switch it off their end and announce the fact to reassure their callers that they are really anonymous.

indeed, but I think the idea was to reassure the public without relying on the other end.

Guess I'm gonna have to look it up now

It's highly likely they've given assurances not to log any details, and given call forwarding service flexibility, it would be quite easy for all calls to just present the 'dialled' number - ie the number the caller used, so they can stay true to their word.

It's a common option, I think, so reception staff at a 'serviced offices' complex can answer with the correct company name, on behalf of both 'one man band' businesses and those with dozens of staff...

There may be circumstances where a court order (or the RIP Act) might require the telecomms firm to provide details (which they may log anyway, even if they don't 'present' the numbers to the recipient of the calls), in the case of a serious crime being investigated.

Crimestoppers is the one that everyone should remember - they always say you can call them anonymously...

Please tell us how across every telco in the world.
