I don't have a phone plugged in to this phone socket, just a filter.
Then you don't need to double filter this
phone socket. You can only try
to double filter the other
phone sockets from which you are losing the sure signal.
EDIT: Just found out Sure Signal is nowt to do with landline phones but just mobiles
. It is on the ADSL side of the connections. Therefore double filtering will not solve your problem; it only applies to landline voice.
