Enjoy all the benefits of landline-level clarity with the freedom of cordless handsets, ensuring a phone is always nearby when you need it. You can even pair this handset with up to 2 cell phones with the push of a button, using Link2Cell to make and receive cell calls and get text alerts through your handsets, which is key for having clear, stable communication in cell dead zones.

One-Ring Scam Alert helps protect you from one-ring scams by displaying a confirmation screen before attempting to call back the unknown phone number.
