Yealink T85W Review -- Australia 2026

Who is this phone for?

The T85W is the right phone when you want built-in Wi-Fi and Bluetooth on a mid-size desk phone with a large non-touch display, without the larger footprint of the T87W. The 5.5-inch display is significantly larger than the T54W's 4.3-inch screen, making it easier to navigate contacts and call history while still fitting on a standard office desk. Buy it for: executives and senior staff who want a premium wireless-capable desk phone, office environments where a cable run to the desk is impractical, and any deployment where Bluetooth headset support is a requirement without a USB dongle. Compare against the T54W: the T54W is the established 4.3-inch wireless phone; the T85W offers a larger 5.5-inch display at a higher price. If the bigger screen matters for daily use, the T85W is worth the premium. If the screen size difference is not a deciding factor, the T54W remains a proven lower-cost option. Compare against the T87W: the T87W has a 7-inch display at a higher price point. If desk space allows and the larger screen would be used, the T87W is the better long-term investment for an executive desk.

Specs at a glance

What's new about the T8 series?

The T8 series is Yealink's current-generation SIP desk phone line, introduced as a newer line alongside the T5 series. The T85W has a larger display than the T54W (5.5 inches versus 4.3 inches); the T87W and T57W both have 7-inch displays. The T8 series uses the SIP protocol and is broadly compatible with third-party SIP devices and leading SIP platforms, but provider support, provisioning requirements and certification vary. Provisioning, configuration, and management work through the same Yealink management platform and the same web-based interface familiar from other T-series phones. The T85W can use an existing SIP extension, but it must still be configured or provisioned; MaxoTel's provisioning process requires the handset's MAC address, model and extension assignment. MaxoTel sells and supports the T85W on its service; for other providers, confirm model support and provisioning requirements before purchase.

Call quality on Australian NBN

The T85W supports dual-band Wi-Fi 6, but call quality over Wi-Fi depends on signal strength, interference, contention and network configuration; no cited testing establishes that it is indistinguishable from Ethernet. The 5GHz band is preferred over 2.4GHz in congested office Wi-Fi environments -- it has more available channels and is less likely to be affected by interference from consumer devices, microwaves, and neighbouring office networks. On 2.4GHz or in environments with high Wi-Fi contention, you may notice occasional jitter during calls. For call-critical deployments, a properly installed and tested Ethernet connection is generally the more predictable choice than Wi-Fi. Follow your VoIP provider's router-specific SIP ALG guidance. Many deployments work best with SIP ALG disabled, but some router and provider combinations require it to remain enabled.

Australian pricing and where to buy

The T85W is stocked by Digiphone and select AU IT retailers. The price at the top of this page is updated nightly via StaticICE where available. As a newer model in the Yealink lineup, availability may vary across AU retailers while stock levels stabilise. Digiphone is a reliable source for current stock and pricing. For multi-unit orders, contact your VOIP provider to check if they offer provisioned Yealink handsets as part of a bundle.

Verdict

The T85W fills the gap between the T54W (4.3-inch Wi-Fi phone) and the T87W (7-inch Wi-Fi phone). If the screen size is a meaningful factor in daily use and you want built-in wireless, the T85W is the right phone. If the screen size difference between T54W and T85W is not a daily factor, the T54W remains a proven lower-cost option. For a desk where the phone will be used heavily all day and the operator wants a modern, large-screen wireless phone, the T85W is a solid current-generation choice.

Frequently asked questions

What is the Yealink T8 series?

The Yealink T8 series is a newer SIP desk phone lineup that Yealink currently lists alongside the T5 series. It includes the T85W (5.5-inch display) and T87W (7-inch display). Both have built-in Wi-Fi and Bluetooth and use SIP, but compatibility, provisioning and feature support must be confirmed with the specific Australian provider or PBX platform.

T85W vs T54W -- which should I buy?

Buy the T85W if you want a larger 5.5-inch display and are happy to pay the premium over the T54W. The T54W has a 4.3-inch display and both phones have built-in Wi-Fi and Bluetooth. If the screen size difference matters for your daily use (contacts, call history, navigation), the T85W is worth the upgrade. If not, the T54W is a well-proven phone at a lower price.

Does the Yealink T85W work on Australian NBN?

The T85W can operate over an NBN internet service when correctly configured for a compatible SIP provider, but provider support, router configuration and provisioning requirements vary. When using Wi-Fi, prefer 5 GHz where its signal is strong and less congested, and validate call quality in the actual deployment area. Follow your VoIP provider's router-specific SIP ALG guidance; although it is often disabled, some router and provider combinations require it to remain enabled. Enable QoS to prioritise voice traffic, particularly on HFC or FTTN connections where jitter can be higher.

Can I connect a Bluetooth headset to the Yealink T85W?

Yes. The T85W has built-in Bluetooth. Compatible Bluetooth headsets pair directly with the phone without a USB dongle. Check the Yealink compatibility list for verified Bluetooth headset models.
