Phone became an integral feature of any hotel room interior. And even if not all guests are accustomed to call their friends or colleagues from an internal telephone in a hotel room (for these purposes, most still use their cell phones), but at least for rapid communication with the manager of the hotel or service hotel phone is a "must have" thing.
At first glance it might seem that the hotel phones are not much different from ordinary household or office phones. But in fact, there is quite a lot of differences, both external and functional in the functional.
