Description
The Yealink SIP-T53 is a 12-line open SIP Prime Business Phone with an adjustable 3.7-inch backlit screen, designed for busy executives and professionals. It is the T53W without built-in wireless: Bluetooth and Wi-Fi are available by adding a Yealink BT40 or WF40/WF50 USB dongle, which keeps the cost down for wired desks. It works with standard SIP phone services, so check that your provider supports Yealink SIP phones before ordering.
Key features
- Adjustable 3.7-inch screen: A 360 x 160-pixel backlit graphical LCD tilts to a comfortable viewing angle for each user and desk.
- 12 accounts and 21 programmable keys: Up to 12 SIP accounts, with 8 LED line keys programmable as up to 21 features across 3 pages, using paperless labels.
- Acoustic Shield and HAC handset: Yealink Optimal HD Voice with Acoustic Shield blocks background noise so callers hear you, not the office, and the handset is hearing aid compatible (HAC).
- Add wireless only if you need it: Bluetooth via the Yealink BT40 dongle and Wi-Fi via WF40/WF50 (WF50 for 5GHz); choose the SIP-T53W if you want both built in.
- USB 2.0 for headsets, recording and expansion: The USB port supports wired or wireless USB headsets, call recording to a flash drive, the EHS40 adapter and up to 3 EXP50 expansion modules (up to 180 paperless DSS keys).
- Turns into a corded-cordless phone: Add the Yealink DD10K DECT dongle to pair up to 4 DECT cordless handsets with up to 4 concurrent calls, so a small team can share one phone system.
- Gigabit, PoE and simple provisioning: Dual-port Gigabit Ethernet with PoE, zero touch provisioning via Yealink RPS and firmware shared across the T53/T53W/T54W/T57W.
Choose your power option: the PoE version runs from a Power over Ethernet switch and has no power supply in the box. Choose "With power supply" if your switch does not provide PoE (adds the Yealink 5V/1.2A power adapter).

Specs are Yealink's, from its current data sheets. "None listed" means the data sheet names no such feature. Yealink uses SIP accounts and VoIP accounts to mean the same thing. Yealink lists the power adapter as optional on most models, so check that your switch has PoE or choose With power supply. Compare all T Series models
