Re: Caller Line Identity - where is it ?
I suspect the that only reason BT can offer Caller ID nationwide is that back in the late 80s, they were still converting to digital exchanges, so were having to spend £millio ns upgrading anyway. It wouldn't have cost them a lot more (relatively) to add facilities for Caller ID.
Of course, the original cable companies who now form NTL could have included Caller ID too (and some did).
