Both the above are true, but I can enlarge on the "storage" aspect.
BT used to supply an enhanced 1471 service called "1471 Extra" that
listed the last five calls. It was quite useful but it was withdrawn 10 years ago without any explanation.
I formed my own theory that maybe OFCOM thought BT were not honoring the withheld flag sufficiently. The service gave you slightly more
information about "withheld" callers than was possible by other
means, including a caller display.
Say someone called you withholding their number. You speak to them so
you know who it was.
1471 extra will say "The caller who withheld their number called today
at [some time]"
Later in the day they call again, still withheld. Perhaps there was
some malicious content this time, but the point is you don't know
who's calling, but, 1471 now says:
"The caller who withheld their number called today two times. The last
time was at [some_later_time]" So now you *do* know it was from the
same number as the previous call.
I wonder if this was the real reason the service was withdrawn?
