No. U 505
Reply and Call Wall Telephone, fitted with Standard Pattern Hand Combination (No. U 175 ), Call Bell, etc.

The "Sterling" Automatic Reply and Call System has been designed for cases where it is not desirable or convenient to use a Central Station Annunciator Switchboard. It is, generally speaking, most useful where the Principal wishes to call all the outer offices, and vice versa.
