Yealink T31P Review : Australia 2026

Common use cases: The T31P suits any small business that needs a reliable, uncomplicated desk phone at a secondary extension. It is a reasonable fit for childcare centre phone setups (room and corridor extensions) and 10-person office configurations where not every desk needs a high-feature handset. For reception desks or staff who handle significant call volume, step up to the T33G.

Who is this phone for?

The T31P supports SIP v1/v2, but compatibility and feature support vary by provider, firmware, and system configuration; confirm support with the provider before purchase. It covers two SIP accounts per the datasheet linked from Yealink's product page (a newer 2024 Yealink datasheet lists four accounts, though still with two physical line keys either way -- confirm with your provider which applies to your unit), handles concurrent calls, and does everything a standard office desk phone is supposed to do. If your staff answer calls, transfer them, and put them on hold, the T31P handles all of it without complaint. Buy it for: reception desks, break rooms, secondary desks, single-staff offices, and any location where the phone is used but not relied on for complex call handling. The T31P supports BLF through two dual-colour line-key LEDs but has a monochrome display and limited physical keys. For a colour display choose the T33G; the T43U also has a monochrome display but offers more line keys and USB expansion.

Specs at a glance

Build quality and design

The T31P is a compact, straightforward desk phone. The body is all plastic, which is standard at this price point, and the construction feels suitable for routine desk use. The keypad has good tactile feedback, the handset is comfortable, and the speaker is adequate for handsfree calls in a quiet office. The tiltable stand has two positions. It is not the most refined-looking phone but it is inoffensive on any desk. The mono LCD is functional, not attractive. You will see caller ID, call status, and time clearly. You will not miss a colour screen unless you have been using one.

Call quality on Australian NBN

The T31P supports G.722 (wideband HD audio) which is the codec that makes a noticeable difference to call clarity on modern SIP systems. The T31P supports G.722 wideband audio, but HD audio requires the SIP service and call path to negotiate a compatible wideband codec. QoS can protect voice traffic during congestion but does not itself enable HD audio. If your NBN connection has jitter or packet loss issues, the T31P supports adaptive jitter buffering and packet-loss concealment. The RTCP statistics accessible via the phone's web interface let you spot jitter or packet loss problems during calls, which is useful for diagnosing NBN quality issues. Key setup note: SIP ALG behaviour varies by router and SIP service. Follow your provider's router guidance, and disable SIP ALG only where it is known to cause registration or audio problems.

Features

The T31P keeps things simple, which is appropriate for an entry phone. Key features worth noting:

• Two line keys. Handles two simultaneous calls, with a clear visual indicator for each. Sufficient for most single-user desks.
• Full-duplex speakerphone. Usable for small group conversations but not designed for conference rooms. For conference calls, look at the Yealink CP925 instead.
• Auto provisioning. Yealink's RPS (Redirection and Provisioning Service) is supported, which means most managed SIP providers including Maxotel can auto-configure the phone when it connects to the network. Manual provisioning via the web interface is also straightforward.
• Dual Ethernet ports. Lets you daisy-chain a PC through the phone rather than running a separate cable. Useful in offices with limited cabling.
• SRTP and TLS. The T31P supports SRTP for media and TLS 1.3 for signalling, but actual call encryption depends on PBX or provider support and configuration, it is not automatic just because the phone supports it. Confirm with your provider if your team handles sensitive conversations.

What works / What doesn't

Australian pricing and where to buy

Stock availability varies across AU retailers, with UMart and MSY showing no availability and Scorptec showing stock at only some locations. Pricing at AU retailers typically sits around $79-$99 AUD depending on the retailer and whether you're buying a single unit or in bulk. Prices are indicative and may include out-of-stock listings; verify both live price and stock before purchasing. It is also available on Amazon AU for convenience purchases, particularly if you need same-day or next-day delivery through Prime. Check both. Retailer pricing is often lower for single units, and significantly lower for multi-unit orders. Bulk pricing may be available for larger orders, depending on the reseller. Contact the retailer directly or ask your SIP provider about bundled handset pricing.

The Yealink T31P is also available from Digiphone, an Australian specialist in business VoIP hardware.

Verdict

The T31P does exactly what a basic AU office desk phone should do, at the best price available. If your use case is straightforward, you don't need BLF keys, and you're not running a call-heavy desk, this is the right buy. The T33G costs more than the T31P, but the premium varies by retailer and stock status; check live prices before purchasing. Spend $100 more and get the T43U if you need USB headset compatibility or Bluetooth support. The T31P is the floor of the Yealink range and it is a solid floor.

Does the Yealink T31P work with NBN in Australia?

Yes. The T31P is a SIP phone that works over any internet connection including NBN FTTP, FTTC, FTTN, and HFC. You will need a SIP provider (such as Maxotel, Vonex, or MyNetFone) and a VoIP-capable router with SIP ALG disabled. The T31P supports G.722 HD audio which delivers noticeably better call quality than older PSTN lines.

What is the difference between the Yealink T31 and T31P?

The T31P adds Power over Ethernet (PoE) support. The T31 requires a separate power adapter. If your network switch supports PoE (802.3af), the T31P is the better choice because it eliminates the power adapter clutter. If you have no PoE switch, the T31 costs slightly less and uses a power adapter instead.

Is the Yealink T31P compatible with Maxotel?

Yes. Maxotel supports auto-provisioning for Yealink phones via Yealink's RPS service. Once you register the MAC address of the T31P with your Maxotel account, the phone configures itself automatically when it connects to the internet. No manual SIP credentials entry is required.

Should I buy the T31P or the T33G?

If your staff make and receive calls regularly throughout the day, the T33G is worth the $30-$40 premium for the colour screen and 4-line support. The T31P is the right call for secondary desks, break rooms, or locations where the phone is used infrequently. If in doubt, buy the T33G.

Can I use a Bluetooth or USB headset with the T31P?

The T31P has an RJ9 analogue headset port only. It does not support USB headsets or Bluetooth natively. If you need Bluetooth headset support, the T43U with an optional compatible Bluetooth USB dongle such as the Yealink BT41, or the T54W with built-in Bluetooth, are compatible options.

Where can I buy the Yealink T31P in Australia?

The T31P is widely available from AU retailers including Mwave, UMart, Scorptec, MSY, Computer Alliance, and MegaBuy. It is also available on Amazon AU. Prices and stock levels vary, so check StaticICE for a current comparison across all AU retailers.
