Review: Nice phone set work for me - Needed a phone just for cablevision Just what I needed first phone plugs into modem second about 100 away in kitchen. Great sound mute ring button easy install power supply with plug so u can slip it through a small hole in a desk power on light so u know it’s on. Happy with the phone!!
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.

### ⭐⭐⭐⭐ A Practical Two-Handset Solution Without Adding A Cell Phone
*by R***G on July 29, 2026*

Let’s face it, traditional landlines are being phased out. I recently encountered this when I needed a telephone extension in another room. Verizon Wireless wanted to steer me toward adding another cell phone, but that was not a workable solution for my needs. I required a cordless phone for the bedroom while keeping the main telephone in the living room. The AT&T EL51203 solved the problem nicely. The main base connects to the telephone line, while the second handset sits in its charging cradle in the bedroom and requires only an electrical outlet. No additional telephone wiring is needed. The sound is clear, the display and keypad are easy to see, and the general setup is straightforward. Note: I would keep a wire splitter at the ready. I already had an AT&T 1740 answering machine that I wanted to continue using. I connected the phone system so that my existing answering machine would still pick up calls. A telephone-line splitter can accomplish this, although the cleaner arrangement is to connect the incoming line to the answering machine’s **LINE** jack and then connect the cordless-phone base through the answering machine’s **TEL SET** jack. Personally, I would avoid paying extra for the version with the answering system built in. That model provides only about 15 minutes of total message-recording time. Since I already owned a separate answering machine, the less expensive EL51203 was the better choice. For anyone who needs one telephone line to serve two rooms, this is a practical and reasonably priced solution. It gave me a living-room phone, a bedroom extension, and clear cordless sound without requiring another cellular line.
