Task
Smaller hotels often avoid investing in an expensive hotel program for checking guests in/out, for billing telephone data or for the room status. However, to prevent misuse, it is imperative to switch authorization for the room phone when checking in and checking out. In addition, it should also be possible to print out the telephone charges incurred on checking out. Many guests also expect that they can alternatively set their wake-up request themselves via the room phone, whereby international guest necessitate a multilingual service.
