I am using this for walk up users in the entrance common area of my office and in my break room. My everyday clients don’t have any issues using this phone. It is a pretty simple and useful phone. It makes my life easier when clients enter into the lobby, they can just pick the phone up and ring right into my office or to the front office. The High-quality 2-way speakerphone, and 3-line appearance makes communication with my receptionist, clients, and employees much easier. I highly recommend this phone, and has the best prices and shipping options I have seen anywhere. I also love the warranty!Š’
