For an entry-level business phone in Australia, the Yealink T33G is the better buy for most desks: a 2.4" colour screen, 4 lines and dual Gigabit ports with PoE. The Yealink T31P costs less and suits lunchrooms, warehouses and desks that only make and take calls: 2 lines, a 2.3" backlit greyscale screen and dual 10/100 ports with PoE.
ARC IP Networks is a trusted Yealink supplier in Australia: genuine Yealink stock with the full manufacturer's warranty, delivered Australia-wide at competitive prices, with local pre-sales help for businesses, installers and IT providers.

Specifications as published by Yealink.
The one spec that matters: Gigabit
If a PC shares the phone's network cable, a 10/100 phone caps the PC at 100 Mbps. The T31P is 10/100, so it belongs on desks where no computer is daisy-chained through it, or where 100 Mbps is fine. The T33G is Gigabit, which is why it is the safer choice for a general office desk even though it costs a little more.
Where each phone fits
T31P
- Lunchrooms, warehouses, workshops and meeting rooms
- Hotel rooms and accommodation
- Any desk without a PC behind the phone
- Large rollouts where a reliable two-line phone is all that is needed
T33G
- General staff desks with a PC on the phone's second port
- Small offices that want a colour screen without a mid-range price
- Users who want a wireless headset: the EHS35 adapter gives remote answer with Yealink DECT headsets
Moving up
When a desk needs more line keys or a bigger screen, the next steps are the T43U (12 lines, wired) and the T54W (16 lines, colour, Wi-Fi and Bluetooth). All of these phones sit happily on the same system, so start with T31P and T33G where they fit and upgrade individual desks later.
Entry-level picks
2 lines, backlit 2.3" screen, PoE, 5-way conferencing. The budget phone that just works.
4 lines, 2.4" colour screen, dual Gigabit, PoE, EHS35 support. The better entry-level desk phone.
Connects a Yealink DECT headset to T3-series phones for remote answer and hang-up.

Common questions
Straight answers from the ARC IP Networks team. Last reviewed October 2026.
The T33G has a 2.4-inch colour screen, 4 lines and dual Gigabit ports; the T31P has a 2.3-inch backlit greyscale screen, 2 lines and dual 10/100 ports. Both are PoE powered with 5-way conferencing.
No. The SIP-T31P has two 10/100 Ethernet ports. If a PC is connected through the phone and needs Gigabit, choose the T33G or the gigabit T31G variant.
Yes. It is the usual entry-level choice for general office desks: colour screen, 4 lines, Gigabit pass-through for the PC, PoE and support for a Yealink DECT headset via the EHS35 adapter.
Yes. Both are standard SIP phones supported by Australian hosted VoIP providers, 3CX, FreePBX and UniFi Talk, and are usually auto-provisioned from the MAC address.
Yes. The T33G supports the Yealink EHS35 adapter, which connects a Yealink DECT headset for remote answer and hang-up. The T31P has an RJ9 port for wired headsets.
Not on a PoE switch; both are powered over Ethernet. On a non-PoE switch, a Yealink power adapter is required.
