The Yealink SIP-T57W sits at the top of Yealink’s T5 series and makes its presence felt right away with a large 7-inch multi-touch color display. Navigation is intuitive and fast, and the touchscreen interface gives the phone a modern feel that stands apart from typical desk phone designs. Support for 16 SIP lines, built-in Wi-Fi, Bluetooth, and USB connectivity makes this one of the most well-equipped desk phones in Yealink’s lineup. Executives, managers, and power users will appreciate not having to choose between features. Pair a Bluetooth headset, connect wirelessly, plug in a USB accessory, and still have lines to spare. Optima HD Voice delivers premium audio quality that makes even long conference calls feel natural and easy to follow. The T57W supports Yealink’s expansion modules for teams that need a larger button panel, and it integrates with most major SIP platforms without difficulty. If you are looking for a flagship desk phone that genuinely lives up to that description, the T57W delivers.
