Yealink SIP-T88W Wireless IP Desk Phone

Communicate clearly by equipping your office with the Yealink SIP-T88W Wireless IP Desk Phone. Designed for versatility with support for up to 16 VoIP accounts and wireless connectivity, this slim IP phone delivers secure, distraction-free conversations.

An adjustable 7" color touchscreen, mounted on a discreet 30° hinge, helps you manage your contacts and calls. Connect either of the two Gigabit Ethernet ports to a PoE compatible network device to transfer data and power over a single cable while using the second port as a passthrough for other devices. Or you can use a separately purchased power adapter to take advantage of the built-in Wi-Fi 6 (802.11ax) support. The USB-A and USB-C 2.0 ports allow you to add a separately purchased headset, storage, or compatible expansions. You can also pair the phone with a separately purchased Yealink BTH88 Bluetooth handset or your choice of headset. The SIP-T88W is powered by Android 13 and may be modified with Yealink's software development kit.
