Viking Electronics RG-10A Ring Booster to 10 Ren

My AT&T cordless phone system (base plus 4 extra handsets) would not ring for incoming calls. Research indicated this type of phone requires more "juice" to activate the electronic ringer. When I setup this Ring Booster between the wall phone outlet and the cordless phone base, the entire cordless phone system began ringing normally and functioning as advertised. I recommend trying this Viking Ring Booster when a new cordless phone system fails to ring/function normally.
