Yealink T46U Review : Australia 2026

Common use cases: The T46U suits high-traffic reception and clinical admin environments where staff need to monitor multiple lines and transfer calls quickly. It features in our guides to medical practice phone systems and is the recommended handset in our best phones for reception desks guide. The 27 programmable keys allow BLF visibility across a full practice team without a sidecar module.

Who is this phone for?

The T46U is the right desk phone for AU offices where call volume is high, multiple lines are in use simultaneously, and BLF visibility of the wider team matters. The 4.3-inch colour screen and 27 programmable DSS keys make it well-suited for team leads, managers, receptionists handling multi-department call routing, and power users in call-heavy roles. The T46U sits between the T43U (12-line, mono screen, USB) and the T54W (16-line, 4.3-inch colour display, built-in Wi-Fi and Bluetooth). Choose the T46U over the T43U if you want a larger colour screen and more DSS keys. Choose the T54W over the T46U if Wi-Fi placement flexibility or built-in Bluetooth headset support is a genuine requirement. If neither applies, the T46U is the more cost-efficient choice.

Specs at a glance

Build quality and design

The T46U is a substantially larger phone than the T33G, with a wide body designed to accommodate the 4.3-inch colour screen and 10 physical line keys, providing up to 27 paperless DSS assignments across three pages of nine. The build is solid and professional. The tiltable stand is adjustable, and the phone sits comfortably on a standard desk without feeling oversized. The 4.3-inch colour screen is a significant step up from the T33G's 2.4-inch display. Caller ID, line status, and BLF indicators are clearly visible from a normal working distance. By default, the DSS key LEDs use solid green for idle, fast-flashing red for ringing, and solid red for busy or in-call status.

Call quality on Australian NBN

The T46U supports the full Yealink codec range including G.722 HD audio and OPUS. On a well-configured NBN connection with QoS enabled and SIP ALG disabled, call quality is excellent. The dual USB ports support recording devices and USB headsets. Codec selection should follow your SIP provider's supported configuration and measured network conditions; NBN access technology alone does not establish OPUS for FTTN or G.722 for FTTC/FTTP as the preferred choice. The T46U supports RTCP-XR/VQ-RTCPXR voice-quality reporting, but viewing detailed per-call MOS and jitter statistics requires a compatible central reporting or device-management platform.

Features

The T46U's feature set is built for busy professional desks:

• 27 programmable DSS keys. 3 pages of 9 keys, each configurable as a BLF key (monitor extension), speed dial, or line appearance. This is what makes the T46U valuable for receptionists and team leads who monitor multiple extensions.
• 2 USB-A ports. Supports USB headsets (compatible models) and USB recording devices. If your team uses USB headsets, the T46U or T43U are the right base phones.
• Dual Gigabit Ethernet. PC passthrough at full Gigabit speed. Important for desks where high-bandwidth PC tasks are combined with active call handling.
• 16 SIP account support. Handles large multi-line deployments. In practice, most AU users register 2-4 lines but the headroom means the T46U is not a limiting factor in any SIP-heavy deployment.
• Expansion module support. The T46U supports Yealink EXP43 expansion modules for additional BLF keys. Each EXP43 adds up to 60 programmable keys across three pages of 20. Up to three modules are supported, but Yealink requires an external 5V/2A power adapter when using two or three modules. Relevant for receptionists managing 20+ extensions.

What works / What doesn't

Australian pricing and where to buy

The T46U is available from several AU sellers, but stock varies: Scorptec and UMart currently list it, Computer Alliance currently marks it out of stock and 'only while stocks last,' and Mwave availability was not confirmed in this audit. Single-unit pricing typically sits around $249-$299 AUD. Prices on this page are updated nightly from StaticICE. For multi-unit deployments (5+ phones), ask your reseller whether volume pricing is available -- this varies by retailer and wasn't consistently confirmed across AU sellers. If you are deploying T46U phones as reception or team lead units alongside T33G general staff phones, ask your SIP provider about mixed handset bundle pricing. Maxotel and similar providers often include provisioning support in their handset bundles.

The Yealink T46U is also available from Digiphone, an Australian specialist in business VoIP hardware.

Verdict

The T46U is the right choice for high-call-volume desks in AU offices where BLF visibility and multi-line management are daily requirements. The 4.3-inch colour screen and 27 DSS keys make it significantly more capable than the T33G for team leads and receptionists. If you don't need Wi-Fi or Bluetooth and your desk has a cabled network connection, the T46U beats the T54W on value. Buy the T54W if Wi-Fi placement flexibility or built-in Bluetooth headset support justifies the additional cost.

What is the difference between the Yealink T46U and T54W?

The T54W adds built-in Wi-Fi and Bluetooth. The T46U has no built-in Wi-Fi or Bluetooth but costs less. If you need to place the phone where a cabled connection is impractical, or if you need to connect a Bluetooth headset without a dongle, buy the T54W. If neither applies, the T46U is the better value.

Can I use a USB headset with the Yealink T46U?

Yes. The T46U has two USB-A ports and supports compatible USB headsets, including supported Yealink UH-series models. The YHS36 is an analogue QD-to-RJ9 headset, not a USB model. Not all USB headsets are compatible. Check Yealink's compatibility list before purchasing a third-party USB headset.

Does the T46U support expansion modules?

Yes. The T46U supports the Yealink EXP43 expansion module, which adds up to 60 programmable BLF/speed dial keys per module (3 pages of 20). Up to 3 expansion modules can be connected, for up to 180 additional keys. This is useful for receptionists monitoring large teams.

Does the Yealink T46U work with NBN in Australia?

The T46U can operate over NBN connections when the network permits SIP traffic and provides sufficient, stable connectivity; correct configuration and SIP-provider compatibility are still required. Configure QoS on your router, disable SIP ALG, and use a SIP provider with Australian infrastructure. The T46U supports G.722 HD audio and OPUS for best NBN call quality.

T46U or T43U. Which should I buy?

Buy the T46U if you need its larger colour screen or more DSS capacity than the T43U's 21 programmable keys; the T43U itself can monitor more than four extensions. Buy the T43U if you need 12-line support and are comfortable with a mono screen, and want to save on per-phone cost. The T43U is more common for standard power-user desks; the T46U is more common for reception and team lead roles.
