DECT 6.0 transmission gives you private, interference-free sound from any room in your home.

Review: Nice unit - Works well with my VOIP phone connected to a router.
Review: Answer this call. Great phone! - If you need a new landline (more people than you think still use them) this is a good choice. I purchased it to replace another brand that did not keep a charge well and I found that I had difficulty hearing. This phone answers those (pun intended.) The battery life is great and the sound quality is a vast improvement to what I struggled with previously. My sons have actually noticed that I do not need them to repeat themselves so much now. I was unsure about the need for the second line addition but I was wrong. Now I do not know how I did without it for so long. Great quality and connectivity. The handset weight is perfect. Large enough to see the number and call missed information, but comfortable enough to be able to use for even the longest call. I find I have an improved range for the phone. Allows for me to even use it on my front porch. Reasonable price. Easy to set up even for those not "tech savvy." This phone arrives quickly. The neutral color allows for a great look in my library/office as well as the living room where the second handset lives.

### ⭐⭐⭐⭐ Great phone, just one downside
*by J***N on August 4, 2025*

Phone looks and works great; although the only downside is that the weight of the base and phone itself is so light that it often falls off it's cradle and the base sometimes falls to the ground without much effort
