Frequently Asked Questions — Yealink SIP-T53
What is the difference between the Yealink T53 and T53W?
The T53W adds built-in Wi-Fi and Bluetooth. The T53 uses optional USB dongles (WF40/WF50 for Wi-Fi, BT40 for Bluetooth) for wireless connectivity.
Does the T53 support Wi-Fi or Bluetooth?
Not built-in. Add the WF50 dual-band Wi-Fi dongle or the Yealink BT40 Bluetooth USB dongle to its USB port, or step up to the T53W for built-in wireless.
Can I add cordless handsets?
Yes — with the DD10K DECT dongle the T53 supports up to 4 DECT cordless handsets.
Can the T53 use PoE?
Yes. It supports IEEE 802.3af PoE (Class 2) over its dual-port Gigabit Ethernet, so a single network cable delivers power and data — no separate power adapter needed.
