This is the Telefon biurowy icon for Windows 10. Here we go. Optimized for 32x32 px, these are the simplest icons in the line style. Downloadable formats are PNG and SVG, among others. Icons8 icon pack is unique in providing a huge number of icons designed by the same team of four designers who create the new icons every working day in the same style and with the same quality. Same cool as the Bat Face, huh.
This icon looks just like a landline phone that you used to see in every home. It looks like it's hanging on the wall. The base is filled with small black squares to represent buttons and a rectangle to represent the screen. There is a handset on the left side connected to the base with a curved line.
