I ordered this phone to use it on a wall. After a disappointment with another phone (Lexibook CP200FR) I paid attention that the screen is "eclairé". This is the case with the Voxtel C115. Office position is really great, I would say 4 or even 5 stars. But. . . screen knows a limited viewing angle. Well, on a wall you have to put in more knees (even very low) to read it. So for my situation, only 2 stars. I communicated this problem AEG and asked them not to put in the data sheet as a wall position is supported. The customer service have answered me that this message will be sent to the marketing department and product development.
