Most of mine are dialled including 020: my phone's memory needs
the 020 prefix entered for Caller ID to work

That's unusual: usually Caller ID lookups in the directory only check
the last 6 digits.

On mobiles that's true but both of the home phones we've had in recent
years require the full code with STD for caller display to work. Maybe
we were just "unlucky"?

Isn't that due to BT sending the CLI for local numbers with the full
code tacked on? In other countries local numbers' CLI is the pure
local number (why else have shorter local numbers?). In most other
parts of the planet local numbers can't be dual-dialled with area
codes in front. Of course BT muddle it up worse with their bad dash
formatting: London nos show up in "02072-221234" format.

Try dialling the local number you know is engaged, then hit 5 for
ringback (ouch, 10p), the CLI will be the number you dialled (no code)
and your phone will probably not recognise it.
