Yealink SIP-T48U Advanced IP Power over Ethernet Corded Phone with Optima HD Voice Technology and 7.0 Inch LCD Touch Screen Colour Display with Backlight (800 x 480 Pixel) – Black

One customer-friendly suggestion to Yealink:Instead of separate sale of expensive custom made dedicated power supply required (most of the time in the absence of the PoE Power over Ethernet), it's better to provide the USB-C power port.It's cheapest solution, readily available in all households.Most of the people may order the above phone device, then be disappointed to find that their Ethernet port doesn't give out power, then they have to place another order for the custom made power supply with extra delivery fee and loss of delivery time.
