This may be the same problem as that described in December by people.

I have surftime (just the evening and weekend one) and my router dials
08440416672 at around 18:30 and keeps the line up until ~7:30 AM. 
This has been working for a couple of weeks (since I got surftime). 
Last night it started to fail to get through.  What happens, as far as
I can tell from the log is that it gets through OK, does some PPP
stuff, including PAP authentication, which succeeds (at least it
thinks so!), and then immediately gets thrown out.  It then iterates
for ever of course.  All the other numbers I've tried, including the
0844091 one, work.  I haven't changed anything in the router (a
netopia 3100) config for a week or so.  My dialling code is 01837 if
it matters.  I've kicked everything (router, ISDN box) I can think of.

I spoke to Demon about this this morning and they say (and I believe
them) that they haven't seen other reports of this (or not today
anyway).

It seems to me that because it's getting as far as doing PPP stuff it
sort of has to be something within Demon, since the ISDN connection is
working.  Could it still be some BT lossage?

Does anyone have any idea what this could be?

Thanks
