We claim the ornamental design for a telephone handset, as shown and described.
FIG. 1 is a front perspective view of the telephone handset;
FIG. 2 is a front elevational view thereof;
FIG. 3 is a rear elevational view thereof;
FIG. 4 is a left side elevational view thereof;
FIG. 5 is a right side elevational view thereof;
FIG. 6 is a top plan view thereof; and,
FIG. 7 is a bottom plan view thereof.
The shading illustrated in the figures (except the diagonal shading on the display screen) is provided merely to represent the contour of the design and is not intended to be illustrative of texture, gloss, or surface decoration.
The broken lines immediately adjacent the shaded areas, which (along with solid lines in some places) define the unshaded regions, represent the bounds of the claimed design while all other broken lines are directed to environment and are for illustrative purposes only. The broken lines and unshaded regions form no part of the claimed design. The entire unshaded central region shown in FIGS. 1 and 2 is unclaimed. However, the display screen (rendered in solid lines with diagonal shading applied thereto) that is shown within this central unshaded and unclaimed portion of the handset is part of the claimed design.
