The Siemens Euroset 5020 is delivered with all necessary cables. Although they are not yet connected (cable from the handset to the phone), but this is done within a few seconds and the phone is ready for use as it is powered by the phone line with current and no external power adapter / battery o. Ä. Are required. The Euroset 5020 is an easy to use and appealing in design phone. Practically especially the integrated Rufnumernanzeige, so you just accept from such frequent calls a person who the caller is. Further, the phone has a built-in clock, which is quite useful. There are 10 one-touch keys that can be individually configured. Also a list of missed calls will be performed. One can also display the date and time of the call in addition to the number of the caller. It is possible both to delete the complete list of missed calls, as well as to delete only individual calls. Next you can when you are in the Anruifliste (missed calls) by simply pressing the / caller / call back in immediately, without having to once again select the number of a button. A star deduction there was because of the very annoying and shrill ringtones. Something's got to be really no longer nowadays. Who uses this phone at the office and receive a lot of calls at some point by the shrill tinkle mistaken ^^ Also I noticed that the optical ring signal (loudspeaker key flashes when a call red) can be seen a bit weak and not really good in daylight (or direct sunlight). Only when it is pitch dark, you can see the red light clearly. Otherwise, I am completely satisfied with the phone. It corresponds to the descriptions and everything works as it should. Of course, one must not expect any high-tech wonders for the price, but this is in my view not necessary also. This phone is well equipped for everyday use and is sufficient for the home or small office (company) from perfect.
