Four-line VoIP phone

The Yealink SIP-T33G is a new entry-level IP phone that supports four SIP accounts and a 2.4 inch 320x240 color display with backlight. It provides Yealink HD Voice and local 5-way conferencing for clear group calls. Dual-port Gigabit Ethernet with PoE support simplifies network cabling and power delivery. Adjustable multi-angle stand suits desk or wall placement.

Upgrade from basic two-line sets

This model replaces simpler handsets that only handle one or two lines and lack a color screen. The jump is worth it when staff need simultaneous account registration, on-phone conferencing without a bridge, or Gigabit pass-through for a PC. PoE class 1 keeps switch budgets low while removing the need for a separate AC adapter.

Small offices and hot-desking

Suits teams that need a cost-effective, standards-based SIP endpoint with visual line-status LEDs and EHS35 wireless headset support. Buyers who want more than four concurrent accounts, a larger touchscreen, built-in Bluetooth or Wi-Fi, or expansion module slots should look at something else.

Questions about this item

How much desk depth does the 212 x 186 mm footprint need?

The phone measures 212 mm wide by 186 mm deep, so allow at least 186 mm of clear desk depth plus room for cables at the rear.

Which cable order avoids a dead PoE link on the dual Gigabit ports?

Plug the network feed into the port labelled LAN and the PC into the port labelled PC; reversing them blocks PoE power to the phone.

When should the 5 V / 0.6 A external adapter be replaced?

Replace the adapter if the phone fails to boot without PoE, shows intermittent power loss, or the DC plug becomes loose after extended use.
