A:AnswerYes, the maximum number of handsets that can be registered to the base unit is 6. KX-TGF775S comes with 5 handsets, which means that you can register one more handset to the base unit.
A:AnswerI unplugged the base's power from the wall to see what would happen. As soon as it was unplugged, the phone set on the base shows a message indicating that the phone set was providing backup power to the base and for you to not remove it from the base. I then called our home and the base showed an incoming call and rang. Thus, it appears that the phone set successfully acts as backup power to the unit.
A:AnswerDear customer, for the Caller ID feature, you need to contact your service provider. If you already have it on a Cox line then it will work if you connected the base unit to VOIP providers' terminal. The following handsets are compatible with this model, for example (KX-): TGFA72(Included Handset); TGFA70; TGFA71; TGTA61; TGFA61; TGEA60; TGEA61.
