Specs are Yealink's, from its current data sheets. Systems show the handset in the box. Range and battery figures are Yealink's "in ideal conditions" numbers, and some handsets list two figures for different hardware versions (V0 to V4). "None listed" means the data sheet names no such feature. Compare all W Series models
