Yealink T43U Review — Australia 2026

Who is this phone for?

The T43U sits in the gap between the T33G and T46U. It does not have a colour screen, but it has two USB ports and supports Bluetooth headsets via the optional DD10K dongle. That makes it the right choice for staff who are on the phone for extended periods and use a headset -- sales staff, support agents, account managers, and anyone who prioritises headset comfort over BLF display size. Buy it for: high-call-volume desks where staff use headsets, offices deploying USB headsets as standard, and managers who want Bluetooth headset support without paying the T54W premium. Step down to the T33G if your staff use analogue RJ9 headsets (or no headset), and a colour screen isn't needed. Step up to the T46U if a large colour screen and more DSS keys for BLF monitoring matters more than USB headset support. Step up to the T54W if you want Bluetooth built in and no dongle required.

Specs at a glance

Build quality and design

The T43U is a mid-size phone with a 3.7-inch mono screen that is larger than the T33G's display but without the colour upgrade. The mono screen is functional and easy to read in office lighting. The extra USB ports on the side are clearly positioned and accessible. Build quality is solid and consistent with the T4 series. The 21 DSS keys are arranged in three columns of seven, with LED indicators showing line status. The Gigabit passthrough ports at the rear mean no speed penalty for PC connections. The overall form factor is similar to the T33G but slightly wider.

Call quality on Australian NBN

The T43U supports the full Yealink codec range including G.722 and OPUS. Call quality on NBN is excellent when QoS is configured and SIP ALG is disabled. The dual USB ports allow a USB headset to handle the audio path directly from the phone, which is the preferred setup for long-duration calls -- USB headsets generally deliver better audio quality than analogue RJ9 headsets at the same price point. Bluetooth headsets via the DD10K dongle work well for mobility within the office. The DD10K is sold separately (typically $30-$50 AUD from AU retailers). It inserts into one of the USB ports and pairs with compatible Bluetooth headsets. Check Yealink's headset compatibility list before buying, as not all Bluetooth headsets are certified. For Wi-Fi connectivity, the WF50 USB dongle (also sold separately) can be inserted in the second USB port. This approach means both USB ports may be used if you want both Wi-Fi and Bluetooth -- in which case the T54W (built-in both) is a cleaner solution.

Features

• Dual USB-A ports -- the T43U's defining feature over the T33G. Both ports are USB-A and support USB headsets, the DD10K Bluetooth dongle, the WF50 Wi-Fi dongle, and USB recording devices. The two ports give flexibility that single-USB phones don't have.
• 12 SIP accounts -- supports up to 12 simultaneous SIP registrations. In most AU SMB deployments, 2-4 are actively used but the headroom is useful for multi-line deployments.
• 21 DSS keys with LED -- fewer than the T46U's 27 keys, but sufficient for medium-complexity BLF monitoring. For reception desks that need to monitor 20+ extensions, the T46U or GXP2170 are better choices.
• EXP43 expansion module support -- the T43U supports the Yealink EXP43 expansion module, adding 60 additional BLF keys. Relevant if BLF monitoring becomes a requirement after deployment.
• Auto provisioning -- supports Yealink RPS zero-touch provisioning with all major AU SIP providers including Maxotel.

What works / What doesn't

Australian pricing and where to buy

The T43U is stocked by Computer & Parts Land, Mwave, UMart, and other AU IT retailers. Pricing typically sits around $179-$219 AUD for the phone itself. The DD10K Bluetooth dongle is sold separately at most AU retailers for $30-$50 AUD. Prices on this page are updated nightly from StaticICE. The T43U is also available on Amazon AU (ASIN B0CH8RHC68). For single-unit purchases, Amazon AU is a convenient option with fast delivery.

Verdict

The T43U is the right phone for desks where a headset is the primary call interface and USB connectivity matters. The dual USB ports and Bluetooth dongle support cover the majority of AU business headset use cases at a lower price than the T54W. If your staff don't use headsets, buy the T33G instead -- it's cheaper and the colour screen is more useful than the extra USB ports for desk phone-only call handling. If you need Wi-Fi and Bluetooth built in without dongles, the T54W is the cleaner solution.

Frequently asked questions

Can I use a Bluetooth headset with the Yealink T43U?

Yes, with the optional DD10K Bluetooth dongle (sold separately for around $30-$50 AUD). The DD10K inserts into one of the T43U's USB ports and pairs with compatible Bluetooth headsets. Check Yealink's headset compatibility list for verified models. If you want Bluetooth built in without a dongle, the T54W is the better choice.

What is the difference between the Yealink T43U and T33G?

The T43U has dual USB ports and 12 SIP lines vs the T33G's analogue RJ9 headset port only and 4 SIP lines. The T33G has a colour screen; the T43U has a mono screen. Buy the T43U if your staff use USB headsets or you need Bluetooth headset support. Buy the T33G if USB connectivity isn't needed and the colour screen is a higher priority.

T43U or T46U -- which should I buy?

Buy the T46U if BLF visibility (colour screen, 27 DSS keys) is the priority -- for reception desks and team leads monitoring multiple extensions. Buy the T43U if USB and Bluetooth headset support is the priority -- for sales staff and call-heavy roles where a headset is worn all day.

Does the Yealink T43U work on NBN in Australia?

Yes. It is a SIP phone compatible with all NBN types. Disable SIP ALG on your router, enable QoS for voice traffic, and register it with any AU SIP provider. USB headsets connected to the T43U handle audio at USB quality, which is typically better than analogue headsets on the same connection.

Does the T43U have Wi-Fi?

Not built in. Wi-Fi requires the optional WF50 USB dongle, which inserts into one of the two USB ports. If you use both Wi-Fi (WF50) and Bluetooth (DD10K) simultaneously, both USB ports are occupied and no USB headset can be connected at the same time. If Wi-Fi and Bluetooth are both required, the T54W (both built in) is the better choice.
