There simply aren’t many phones that will support NSC requirements. With that being said, KCI will produce phones that would obviously meet standards. There will be 2 types. There are cellular phones, and terrestrial phones. KCI will produce both since there are so many landline phones that do not NSC requirements, and with this company building both types and meeting with the NSC requirements, it assures that the customer has the device they need. There will be DECT phones which are what one might think of when they hear cordless phone. It has a standard numeric keypad, and will use a DECT base station. There will be Wifi Phones which will actually be built on the Kal-OS (phone), and will look a lot like a cellular phone, but this will be Wifi only. There will also be cellular phones which will be available to the market, and even one exclusively for education purposes.
Obviously, everyone needs a phone. While terrestrial phones are becoming more rare, that would just mean a lower production inventory to meet the demand. However, there are still people that would want a home phone for one reason or another. They should have choices that will meet their needs.
