Summary: Bought the phone to use it with a headset when working from home. It does the job perfectly. My phone does have a little problem with the clock resetting itself. No matter how much I set the time, the clock resets itself after a little while so I gave up. Other than that, the phone fulfills its chief function as expected.
Summary: Replaced an elderly answerphone in the home 'office', where that feature is no longer required. Does the job well, and I couldn't find anything better on the market. Weaknesses (not fair to call them 'faults') that have dropped the single star would be insufficient record of received calls (number only, not when), speaker volume, no visual 'call' signal (neither current nor missed). Or I might have misread the manual, of course.
