### ⭐⭐⭐⭐ 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.
