Anyone seen this before and know what the problem is?

Actually, yes. In the occasion I saw it it was a line fault - but it
was difficult convincing BT of this.

I have heard of the same thing happening due to a faulty filter,
though, so given that they only cost a couple of quid it might well be
worth trying that first.

Remember that an on-hook telephone is IIRC a shorted phone. More or
less. The point of the filter is not not make it shorted with respect to
high frequencies.. if taking a phone off stats the broadband, the filter
is not in the right place or not doing its job.
