Here is an idea for our communications project. Its some sort of dock that has a DSL Input, power input, and 4 usb ports. Do u know how u go home and u usually put ur cell phone in ur room or on ur charger? And lets say u go downstairs or something and ur somebody calles ur cellphone and u have no idea and cannot hear ur cellphone ringing. So basically u can connect ur dock to ur landline phone, and also connect up the phone to the dock, and whenever somebody calls ur cellphone, no matter where u are in the house, ur landline will also ring. Just wondering if this idea exist's yet?
