That's interesting - and corresponds with my belief that CLID is witheld by

Nothing to say that we're both right ... if BT don't have a policy that
link ex-dir to CLI blocking, or if they have done different things at
different times. My line was ordered with ex-dir from the start, not
added later, line was installed recently (i.e not a long standing line
that existed before CLI was available)
