Why Yealink Dominates the Business Phone Market

Yealink has become the default choice for business VoIP phones worldwide, and for good reason. They offer excellent build quality, crystal-clear HD audio, and broad compatibility with virtually every VoIP platform on the market — from hosted services like 3CX and Telavox to on-premise PBX systems.

For businesses across Belfast and Northern Ireland upgrading from traditional landlines to VoIP, Yealink phones are our most recommended handsets at Drakos Systems. Here's a detailed comparison of every model in the current range to help you choose the right phone for each role in your organisation.

Yealink T31P / T31G — The Budget Workhorse

• Price: £40-55
• Display: 2.3" 132x64 pixel LCD (no backlight)
• Lines: 2 SIP accounts
• Audio: HD voice, handset and speakerphone
• Connectivity: T31P has 10/100 Ethernet; T31G has Gigabit Ethernet
• PoE: Yes (both models)
• Best for: Warehouse staff, kitchen areas, common areas, and any role that just needs to make and receive calls

The T31 is Yealink's entry-level phone, but don't let the price fool you — the call quality is excellent. It lacks a colour screen and Bluetooth, but for basic calling it's hard to beat at this price point. We deploy these extensively in hospitality, retail, and warehouse environments across Northern Ireland.

Yealink T33G — The Smart Entry Level

• Price: £55-70
• Display: 2.4" 320x240 colour LCD
• Lines: 4 SIP accounts
• Audio: HD voice with Opus codec support
• Connectivity: Dual Gigabit Ethernet ports
• PoE: Yes
• Best for: General office staff who need a clear display and basic features without breaking the budget

The T33G is the sweet spot for most office workers. The colour screen makes it much easier to navigate menus and read caller information. Four SIP lines mean it can handle multiple extensions or accounts. For a typical office deployment, this is the model we recommend for the majority of desks.

Yealink T43U — The Mid-Range Performer

• Price: £85-100
• Display: 3.7" 360x160 LCD
• Lines: 12 SIP accounts
• Audio: HD voice, USB headset support
• Connectivity: Dual Gigabit Ethernet, USB 2.0 port
• PoE: Yes
• Expansion: Supports EXP43 expansion modules for additional BLF keys
• Best for: Receptionists, team leaders, and staff who handle high call volumes or need to monitor multiple lines

The T43U's USB port is a significant upgrade — it allows direct connection of USB headsets (like Jabra and Plantronics), USB recording devices, and USB dongles for Bluetooth and WiFi. The support for expansion modules makes it ideal for receptionists who need to see the status of dozens of extensions at a glance.

Yealink T46U — The Power User's Choice

• Price: £140-160
• Display: 4.3" 480x272 colour LCD
• Lines: 16 SIP accounts
• Audio: HD voice, Opus codec, USB headset support
• Connectivity: Dual Gigabit Ethernet, dual USB 2.0 ports
• PoE: Yes
• Expansion: Supports up to 3 EXP43 expansion modules (60 additional BLF keys)
• Best for: Managers, directors, and anyone who needs a premium desk phone with extensive features

The T46U is our recommendation for managers and senior staff. The large colour display is easy to read, the dual USB ports support both a headset and a recording device simultaneously, and the ability to add up to three expansion modules means it can serve as a mini-switchboard. The build quality feels premium — it's a phone that looks the part on an executive desk.

Yealink T48U — The Visual Communicator

• Price: £170-200
• Display: 7" 800x480 colour touchscreen
• Lines: 16 SIP accounts
• Audio: HD voice, Opus codec, USB headset support
• Connectivity: Dual Gigabit Ethernet, dual USB 2.0 ports
• PoE: Yes
• Best for: Reception desks, executives who prefer touchscreen interfaces, and businesses wanting a modern look

The T48U's 7-inch touchscreen is its standout feature. Navigation is intuitive — tap contacts, swipe through call logs, and manage calls with familiar smartphone-like gestures. It's particularly effective at reception desks where staff need to quickly find and transfer calls. The large screen can display company branding and wallpapers, adding a professional touch.

Yealink T58W — The Flagship

• Price: £220-280
• Display: 7" 1024x600 adjustable colour touchscreen
• Lines: 16 SIP accounts
• Audio: HD voice, full-duplex speakerphone, built-in Bluetooth 4.2, built-in WiFi
• Video: Optional CAM50 USB camera for video calls
• Connectivity: Dual Gigabit Ethernet, USB 2.0, Bluetooth, WiFi
• PoE: Yes
• Best for: C-suite executives, boardrooms, and businesses that need video calling capability on desk phones

The T58W is Yealink's flagship desk phone. Built-in Bluetooth means you can pair your mobile phone and handle both mobile and desk calls from one device. Built-in WiFi means it can be placed anywhere without running an Ethernet cable. Add the optional CAM50 camera and you have a video phone for face-to-face calls. It's the most capable desk phone Yealink makes.

Setting Up Yealink Phones

One of Yealink's strengths is how easy they are to deploy:

• Auto-provisioning: Configure your VoIP platform's provisioning server and Yealink phones will automatically download their configuration when plugged in. No manual setup needed per phone
• Plug and play with hosted VoIP: Most hosted VoIP providers (including those we partner with at Drakos Systems) support Yealink auto-provisioning. Plug the phone into your network and it configures itself
• Manual setup: Access the phone's web interface (type its IP address into a browser), enter your SIP server address, username, and password. Takes about 2 minutes per phone
• Redirection service: Yealink's RPS (Redirection and Provisioning Service) can point phones to your provisioning server automatically based on MAC address

For businesses deploying 10+ phones, auto-provisioning saves enormous amounts of time. We configure provisioning templates for our clients so that new phones are ready to use within minutes of being plugged in.

Which Yealink Phone Should You Choose?

• Basic calling only: T31G (£45-55)
• General office staff: T33G (£55-70) — best value for most users
• Receptionists and high-volume callers: T43U (£85-100) with expansion modules
• Managers and directors: T46U (£140-160)
• Reception desk (touchscreen): T48U (£170-200)
• Executives and video calling: T58W (£220-280)

Most businesses end up with a mix: T33G phones for the majority of staff, T43U or T46U for managers and reception, and perhaps a T58W for the boardroom or MD's office.
