It is an image of a land-line telephone handle from several years ago, set sideways to show its full length. Beneath the telephone handle is an arrow pointing down, which suggests placement on its cradle which would signify the end of a call.
This End Call icon is a responsive icon. This means that it's optimized for four resolutions, from tiny 16x16 until highly detailed 80x80. The style comes from the latest Microsoft Office
, which makes it perfect for any Windows applications, in particular, those with ribbon toolbar control. Unlike other icon packs that have merely hundreds of icons, this monster icon pack contains 15,700 icons, all in the same style and quality.
