A:AnswerIt is meant to work like a landline phone, but it will work with any "Home Phone" arrangement. I have mine hooked up to a Verizon "Home Phone" over-the-air device and it works just fine with it. Of course, it will not receive texts and will not run any "apps."
A:AnswerSince the handsets tell me that they can be paired to a cell phone via bluetooth, I see no reason why a headset wouldn't work. I don't use one, but after looking at the bluetooth on the handsets, I can't see that you'd have any problem.
A:AnswerIDK if you can correct this but please keep this in mind once the person on the other end is leaving a message you can begin to here what their saying. I don't know how bad you need to hear your greeting message but I guess the company figured it was unnecessary to play that back to you.
A:AnswerNot sure I understand the question, but you plug in the base unit into a wall outlet, and you plug the charging bases for the two handsets into wall outlets, so yes, you can plug in the unit.
