I don't have any experience with FS connecting over ISDN so can't help
you much further on the FS configuration:-(

However on the lines, I would be very tempted to see if you can borrow
a BRI tester, or what I've frequently used in the past is an
Eicon/Dialogic card as the test functions (under windows) are nearly
as good, that might help you see if it _is_ a BT problem, or a FS
configuration issue. It would need a 2k/XP machine, but something like
is what I have used in the past. I think I might have one of the
PCMCIA ones somewhere, but I'd need to test it still works

I'm fairly sure that the "6 digits to switch" is what they are sending
to you, not what they are expecting from you. I can't access out
remaining BRI (Avaya) PBX from here, but on our PRI (again Avaya)
switches, we are sending 10 digits.
