Yealink T7 Series Compared: T73U vs T73W vs T74U vs T74W vs T77U

The T7 family at a glance

All five T7 phones share the same slim body, touch-sensitive message/headset/mute buttons, dual Gigabit Ethernet and Three Rings security. The differences come down to three things: screen size, number of line keys and whether Wi-Fi and Bluetooth are built in.

Model positioning summarised from Yealink's T7 Series product pages and datasheets. The SIP-T73W and SIP-T74W are not yet listed in our online shop; call us to check supply.

Design: slimmer than the T4 and T5, with touch-sensitive buttons

Yealink describes the T7 as an "all-new" design with a slimmer body than the phones it replaces. The message, headset, mute and page buttons are now touch-sensitive, with indicator lights on mute, headset and paging, and there's a stand with two angles. The screens support light and dark themes and an accessibility mode, which helps in shared offices where several people use the same phone. Every T7 has a security keyhole, so phones on public counters can be locked to the desk.

Screen and keys: T73 vs T74 vs T77U

This is the main decision. The T73U and T73W have a compact 2.8-inch 320 x 240 colour screen and 8 LED line keys, which page through to 40 programmable keys. That's plenty for someone who handles their own calls and a handful of speed dials or colleagues' lines.

The T74U and T74W move to a 4.3-inch 480 x 272 screen with 10 line keys (50 over five pages), 16 SIP accounts and 10-way local conferencing. The bigger screen shows names next to each key, so staff who park, pick up and transfer calls all day can see more without paging.

The T77U replaces the physical line keys with a 7-inch 800 x 480 capacitive touch screen holding 84 one-touch keys. It suits a team leader watching a whole team's busy lamps or a receptionist who wants a large, clear screen. The touch screen is adjustable, and the T77U is the only T7 with both USB-A and USB-C ports.

U or W: do you need built-in Wi-Fi and Bluetooth?

The T73 and T74 come in two versions that are identical apart from wireless. The W models (SIP-T73W, SIP-T74W) build in dual-band Wi-Fi 6 (802.11ax) and Bluetooth 5.0. Bluetooth can connect a headset and a mobile at the same time, or connect the phone to a PC as a peripheral, and close-to-pair gets a Yealink headset connected quickly.

The U models don't have built-in radios. You can still add Wi-Fi with Yealink's WF50 USB dongle, or Yealink Bluetooth headsets with the BT51 dongle, but most offices buying the U model simply run them over Ethernet and PoE. Choose a W model for heritage-listed buildings, short-lease and pop-up offices, or any desk where new cabling is slow or not allowed. The T77U has no W version.

Security: Yealink's Three Rings on every T7

The T7 Series shares the T8's security design, which Yealink calls the Three Rings:

• Core Ring (device integrity): Trusted Execution Environment, secure boot verification, and firmware encryption with signature certificates.
• Shield Ring (network protection): 802.1X authentication, WPA3, and protection against script injection and cross-site attacks.
• Guard Ring (transmission security): TLS 1.3, SRTP media encryption and AES-256 encrypted configuration files.

The phones also support OpenVPN and L2TP VPN for staff working from home. If your IT provider works to the ACSC Essential Eight, signed firmware and central patching through Yealink's YMCS or YDMP platform make phones easier to keep up to date. For practices that handle personal information under the Privacy Act, encrypted calls and configuration files are a sensible default.

Audio: Acoustic Shield and a 3 W speaker

Every T7 has an HD handset and speaker, a hearing-aid-compatible handset and Yealink's Acoustic Shield, which reduces background noise when you're on the handset. The T73 and T74 add Smart Noise Filtering; the T77U steps up to AI noise cancellation. Yealink quotes a 3 W speaker across the range for a louder hands-free speakerphone. HD voice uses the G.722 wideband codec, with AMR-WB available as an option.

Headsets and accessories

All T7 phones have an RJ9 headset jack and USB for wired headsets. Yealink lists USB or Bluetooth control of the UH38 and the CP900/CP700 speakerphones, and USB control of the UH34, UH36 and UH37 wired headsets (answer, end, mute, volume sync and more). Bluetooth headsets such as the BH71, BH72 and BH76 connect directly to the W models, or to the U models through the BT51 dongle. The EHS40 adapter covers wireless headsets that need hook-switch control.

Where the T7 sits: T7 vs T8 vs T4 and T5

Yealink's current desk-phone range runs T3, T4, T5, T7 and T8. The T7 is the new mainstream range. In our view it's the natural next step from the T4 Series (T43U, T46U, T48U) and the T53/T54W: similar screen sizes, but a slimmer body, more programmable keys and the T8's Three Rings security.

Compiled from Yealink's T7 and T8 Series datasheets and product pages.

The closest pairs are the T77U and T87W, which share a 7-inch 800 x 480 touch screen with 84 one-touch keys. The T87W adds built-in Wi-Fi 6 and Bluetooth 5.0, a red emergency button and an antimicrobial finish. If you need any of those, read our Yealink T8 Series comparison; otherwise the T7 covers the same calling features for less.

Which T7 phone for which Australian workplace?

Upgrading from the T3, T4 or T5 Series?

Most T7 models line up with an older Yealink phone of the same screen size, so a like-for-like swap is simple:

Upgrade mapping is an ARC IP Networks suggestion, based on Yealink datasheets. Check feature support with your PBX or hosted platform before a full rollout.

Does the T7 work with my phone system?

The T7 Series is a family of open SIP phones, with 12 SIP accounts on the T73 models and 16 on the T74 and T77U. They work with 3CX, FreePBX/Asterisk, Broadsoft-based hosted platforms and the hosted PBX and SIP trunk services from Australian NBN and business-voice providers. For larger rollouts, Yealink supports auto-provisioning over HTTPS, PnP, TR-069, Zero-Sp-Touch and its YMCS/YDMP management platforms, so an MSP can ship phones straight to a site in Parramatta, Geelong or Townsville and have them register on first boot.

On PoE, the T73 and T74 are 802.3af class 2 devices drawing under 2 W by Yealink's figures, and the T77U is class 3 at about 2.4 to 3.2 W, so any standard PoE switch powers a full floor easily. See our guide to running Yealink phones on UniFi and MikroTik networks for VLAN and QoS settings.

The T7 is not a native Microsoft Teams phone. For Teams Phone, see our guide to Yealink's MP-series Teams phones.

If you program a key to dial 000, test it with your hosted PBX or SIP provider first and confirm that the site's emergency address is registered correctly.
