Ring Booster with Caller ID Support! (Model RG-10A)
NEW
The RG-10A ring booster provides the ability to ring additional phones when the phone company's ring voltage or another product's ring generator (such as ISDN Terminal Adapters) aren't enough. The RG-10A will boost REN to 15.0 and will work flawlessly with Caller ID services provided by the phone company.
