About This Phone
The Unifon project, which never went into production, involved creating an all-in-one telephone, i.e. a complete telephone in a single handset. The Unifon project tackled problems that designers and engineers in the telephone industry had struggled with throughout the entire 1900s. It had several imitators. Bell's laboratories were already well aware of the Swedish project in 1946, and their Trimline, dial-in-hand telephone from 1964 is very much based on Ericsson's project. This was also the case to an even greater extent with the telephones of the 1980s, such as the Italian Cobra, the Swedish Ouno and the Norwegian Tastafon Compact.
