Yealink T33G Review — Australia 2026

Who is this phone for?

The T33G hits the sweet spot for Australian SMB deployments. It is the phone that covers 90% of general staff desk requirements: multiple lines, a colour screen that shows who is on which line, BLF visibility for busy/available status, and reliable call handling on NBN. Buy it for: general staff desks, customer-facing roles, small team offices, and any desk where call volume is moderate and visibility of line status matters. It replaced the T41S (discontinued) as the main mid-range recommendation, and the colour screen makes a genuine practical difference when managing multiple lines or monitoring team availability. Step down to the T31P if budget is the primary driver and your staff only handle one call at a time. Step up to the T43U if you need USB headset support or Bluetooth headset integration, or to the T46U if a larger colour screen is a priority.

Specs at a glance

Build quality and design

The T33G is noticeably more refined than the T31P. The body is slightly slimmer, the colour screen gives it a cleaner look, and the overall build feels more consistent with a modern office environment. The Gigabit passthrough port is a genuine upgrade from the T31P's 100Mbps port, which matters if you're routing a PC through the phone connection. The colour screen is 2.4 inches, which is small but large enough to clearly distinguish line status, caller ID, and BLF indicators. The LED indicators on the four line keys give immediate visual feedback on call status. Physical button feel is solid and the handset audio quality is good.

Call quality on Australian NBN

The T33G supports G.722 HD audio and OPUS, which gives it the best codec range of any phone in the T3 series. On a well-configured NBN connection with QoS enabled and SIP ALG disabled, call quality is noticeably better than older PSTN landlines. OPUS support is increasingly relevant as more AU SIP providers offer it for improved compression on lower-bandwidth links. On FTTC and FTTP connections, call quality with a managed SIP provider like Maxotel is excellent. On FTTN connections at lower sync speeds, you may notice slightly reduced clarity during periods of heavy network use, but this is a network issue rather than a phone issue. The T33G performs consistently across NBN connection types provided QoS is in place. SIP ALG: Disable it. On Telstra, TPG, and most consumer NBN routers this setting causes SIP registration drops and one-way audio. It is the single most common cause of call quality complaints on AU NBN SIP deployments.

Features

The T33G is well-specified for a mid-range phone. Key features that matter for AU business use:

• Colour BLF display. The 4 line keys with colour LED indicators let staff see which lines are in use at a glance. This is the primary reason to choose the T33G over the T31P for any desk where call management visibility matters.
• 4 SIP accounts. Supports 4 simultaneous SIP registrations. In practice, most SMB deployments use 1-2, but having 4 available means you can assign multiple numbers to a single phone without limitation.
• Gigabit passthrough. Unlike the T31P, the T33G has dual Gigabit Ethernet ports. PC passthrough works at full Gigabit speeds, which matters if staff are running video calls or large file transfers through the phone's network port.
• OPUS codec support. OPUS is a modern efficient codec that performs well on lower-bandwidth or variable-quality NBN connections. Not all AU SIP providers offer it yet, but those that do (including Maxotel) will use it by default when available.
• Auto provisioning via RPS. Zero-touch setup with any SIP provider that supports Yealink auto-provisioning. Maxotel, Vonex, and most managed SIP providers in AU support this.

What works / What doesn't

Australian pricing and where to buy

The T33G is widely stocked across all major AU IT retailers. Scorptec, Mwave, UMart, PLE, and MSY all carry it regularly. Pricing typically sits around $119-$149 AUD for a single unit, depending on the retailer and current stock. Prices on this page are updated nightly via StaticICE. For bulk purchases of 5+ units, most AU resellers offer volume pricing. Some SIP providers including Maxotel offer handset bundles that include provisioning support, which is worth considering if you are deploying more than 3-4 phones at once. Amazon AU also carries the T33G and is useful for fast delivery, though retailer pricing is usually lower for multi-unit orders. Check both before buying.

Verdict

The T33G is the most recommended desk phone for Australian SMBs in 2026. The colour screen and 4-line support make it the right phone for any general staff desk where call management visibility matters. The price premium over the T31P is justified by the colour display and Gigabit passthrough alone. If your staff don't need USB or BT headset support, and you don't need Wi-Fi, the T33G is the phone to buy. For power users or high-call-volume desks, the T43U or T46U are the logical next steps.

Frequently asked questions

Is the Yealink T33G compatible with Maxotel and other AU SIP providers?

Yes. The T33G works with all major AU SIP providers including Maxotel, Vonex, MyNetFone, Aussie Broadband, and others. Auto-provisioning via Yealink's RPS service is supported by most managed providers, which means the phone configures itself automatically when connected to the network.

What replaced the Yealink T41S in Australia?

The T41S was discontinued and is no longer in Yealink's active lineup. The T33G is the recommended replacement for most AU deployments that previously used the T41S. It offers a colour screen (upgrade from the T41S mono), 4 SIP accounts, and Gigabit passthrough at a comparable price point.

Does the T33G work on NBN in Australia?

Yes. The T33G is a SIP phone that works over any internet connection including all NBN types. For best results, enable QoS on your router, disable SIP ALG, and use a SIP provider with AU-based infrastructure. The T33G supports G.722 HD audio and OPUS for good call quality on NBN.

T33G vs T43U. Which should I buy?

Buy the T43U if your staff need USB headset support or Bluetooth integration, or if you manage 12+ simultaneous lines. Buy the T33G if your needs are standard (4 lines, colour screen, analogue headset) and you want to save $60-$80 per phone. For most general staff desks, the T33G is sufficient.

Can I connect a PC through the Yealink T33G?

Yes. The T33G has dual Gigabit Ethernet ports. One for connecting to your network switch and one for passing the connection through to a PC. This is a Gigabit connection (unlike the T31P's 100Mbps passthrough), so it works at full speed for normal office PC use.

Does the T33G support Bluetooth headsets?

No. The T33G does not have built-in Bluetooth and does not have a USB port for a Bluetooth dongle. It uses an RJ9 analogue headset port only. If you need Bluetooth headset support, the T43U (with the optional DD10K Bluetooth dongle) or the T54W (built-in Bluetooth) are the correct choices.
