Yealink T73U IP Phone Overview

The Yealink T73U is a corded IP phone designed for office environments that require reliable voice communication. It runs Linux 6.1 and supports up to 12 SIP accounts for multi-line handling. A 2.8-inch 320x240 pixel backlit display provides clear call information. The device includes a TEE hardware encryption solution for secure conversations.

Deployment and Mounting Flexibility

This unit integrates into networks using Power over Ethernet, removing the need for a separate power adapter. It can be placed on a desk using the included stand or fixed to a wall for space-saving installation. A dual system function and unified firmware across the T7X series simplify mass deployment and ongoing maintenance for IT teams.

Capacity Limits and Constraints

The handset comfortably manages 12 simultaneous SIP registrations for busy workstations. The fixed 2.8-inch display size restricts visible directory entries and call logs compared to larger models. Buyers needing wireless mobility, Bluetooth headset pairing, or a colour touchscreen should consider other product lines.

Questions about this item

How many SIP accounts can the Yealink T73U register simultaneously?

The phone supports up to 12 SIP accounts for multi-line operation.

Does the T73U require a separate power adapter for all-day use?

PoE support lets the phone draw power from the network cable, so no external adapter is needed.

What mounting hardware must already be in place for desk or wall installation?

The unit is both stand-mountable and wall-mountable, so a flat surface or standard wall bracket is sufficient.
