Can the DS6521 help the poor cell phone reception in my house?
If your cell phone has poor reception in your home, the DS6521 cannot improve the

your cell phone at that location while you use DS6521 cell line. In order for this to work, the
telephone base must be within 30 feet of the cell phone.
The listening volume of my cell call is too loud or quiet.
