Abstract

A telephone set is provided including at least one deposit trough for the handset provided in the stationary housing part. A filler member is arranged in the edge region of the deposit trough, this filler member terminating flush with the deposit trough during table-top operation of the telephone set, whereas a nose connected thereto of one piece projects beyond the contours of the deposit trough upon use of the telephone set as a wall unit. The filler member should be securable such that the user himself can refit the telephone set to the two operating positions in a simple way. To this end, a freely accessible cutout into which the filler member can be introduced in two use positions is provided in the edge region of the deposit trough.
