Maybe the system works by routing the calls abroad and back in again -
so even with a UK caller ID, BT (and some others, but not all) don't
"trust" the incoming caller ID.
Caller ID in the UK seems to work on a "trust" and "Gentlemans handshake"
sort of agreement - and telcos are not obliged at all to trust and pass
on incoming caller ID, although most do, and some are more tolerant
