I need some advice here.
As we have landline for broadband via the Post Office. We do have a old ex-BT which we can use on the phone, but it has to be disconnected most of the time otherwise it messes the router up etc.
Is there a way to redirect the line to a old mobile phone so that rings when someone phones the landline and saving us from disconnecting the router to use the old phone to see who rang etc? Please advise.
