Developed with a very ergonomic and appealing design the Yealink 4X IP Telephone series is built for modern business communications. The Yealink SIP-T48S is a high-end phone designed for demanding work environments with Gigabit Network infrastructure.

The large 7 inch 800 x 480 pixel touchscreen color display with 29 build-in DSS keys is supporting line status information and paperless label design. If the T48S is used in an admin or reception environment you can connect up to 6x EXP40 expansion modules allowing you to add up to 240 additional buttons.

If the phone is setup in a busy environment with many phone calls every day you can connect a corded or a cordless headset.

A Bluetooth headset allows you to roam up to 10 meters from your desk and when leaving office you can continue to use it with your mobile phone. To pair a Bluetooth Headset with the Yealink SIP-T48S simply insert a BT40 USB dongle in the phones USB port.
