There may be problems with some of the exchanges not being able
to handle international numbers in the callerid software (e.g.
more digits). That's the only reason I can imagine BT mark all
international calls with UNAVAILABLE when they clearly do have
the number to hand.

I get a number of calls from one overseas number direct to a mobile
and they variously show up as the number itself, a meaningless
number, international or withheld. How well the originating CLI
survives seems to depend entirely upon the route taken which these
days of purchase of bulk data can bear no relationship to the
physical localities.

I vaguely remember seeing a BT document about this some years ago and
believe they made the decision to show "International" as it was at
least consistent rather than varying the display of information
depending upon the time of day and direction the wind was blowing
from! (I could equally be entirely wrong as it was a decade ago).
