My cordless phone will not receive the caller ID when plugged into a

socket, thus removing the filter (and disconnecting Broadband!) the caller
ID works fine.

Any ideas on how to resolve this?

Try the phone in a straight line splitter(T-piece) while the adsl is on
if the phone is a digital dect one it may not need the filter.
I ran both the adsl and my dect phone for ages this way with no
problems, only needed a filter when I attached an analogue phone
on an extension.
