Panasonic KX-TG2570B 2.4 GHz DSS Cordless Phone with Answering System and Caller ID (Black)

The answering machine built into the base unit is all digital and can record up to 14 minutes worth of messages. You can retrieve and delete messages by using the handset, with which you can also turn the machine on and off. The handset itself is solidly built, with a rubber inlay on its side to provide a better grip and absorb shock if it's dropped. A three-line, high-resolution backlit LCD graces the front of the handset and displays all sorts of information, from caller-ID names and numbers to the menu items that comprise the phone's interface. This interface is the worst thing about the KX-TG2570B, as it's practically impossible to use without referring constantly to the manual. However, once mastered, it let us add our own phone directory to the unit and edit or delete Caller ID entries that automatically were added to the phone's database.

On the upside, the KX-TG570B's range and ability to penetrate walls blew away other 900 MHz cordless phones we've tested. With the base unit in a basement office (which in turn was in a brick building), we were able to leave the building and roam all over the parking lot with no loss in voice clarity. Additionally, the audio quality was superb as long as we stayed within range, with no hissing, popping, or other static present.

There are a few things about the KX-TG2570B that just don't make sense. You can answer incoming calls using the speakerphone in the base unit, but because it has no keys you can't place a call with it. The bay used to recharge the handset provides a loose fit, meaning the handset can easily tip forward and lose its electric connection. There's no mute button, and although the buttons on the handset are backlit, those on the base are not. This is a great-sounding phone with good range, but if you're looking for perfection, there are better options. --T. Byrl Baker

While conventional phones transmit and receive signals within the same band (which can result in interference between these signals), 2.4 GHz GigaRange Extreme SST cordless phones employ the use of two different frequencies: 2.4 GHz on the base and 900 MHz on the handset. This means that interference between these signals is minimized, thereby enhancing clarity and boosting range. A unique, proprietary circuitry design also helps these phones resist interference from other devices that share similar bands, like microwave ovens. Panasonic 2.4 GHz GigaRange Extreme cordless phones utilize SST in both the 2.4 GHz and 900 MHz bands.

This unique twin-band transmission, coupled with rugged design, allows you to take your conversations outdoors and to the extreme. Panasonic has also included a 2.5-millimeter headset jack and belt clip for hands-free operation. Its relatively small design enables you to simply slip the phone into your pocket when you're not using it. In addition, these phones are designed to stand up to everyday wear and tear. They are shock resistant and splash resistant, guarding them against damage caused by occasional dropping or spilling.

The KX-TG2570 also boasts two-way paging and automatic intercom, dual antenna system, backlit three-line LCD display on handset, 50-station caller ID memory and dialer, 30-station phone directory and dialer, navigator key, seven-hour battery charging system, and up to eight hours of talk time. The answering system includes call screening, skip/FF, repeat/rewind, and all/individual erase.
