Best Office Phones (2025): Key Takeaways Make sure your choice fits the job by deciding desk or room, wired or cordless, and how many lines (SIP accounts) you need. Then confirm your platform (e.g. RingCentral, 8×8, GoTo, Vonage, etc.) supports the exact model before making bulk orders.Teams on hunt groups or overflow typically need six to 16 lines. Solos and secondary desks can work with four. BLF keys (free/busy lights) save seconds, and heavy-transfer roles should pick phones that accept a sidecar or expansion module.Wired versus Wi-Fi versus DECT (Digital Enhanced Cordless Telecommunications). Power over Ethernet (PoE) is most reliable and tidy; use Gigabit passthrough if a PC shares the Ethernet drop. Built-in Wi-Fi saves cabling in serviced offices (check 2.4 and 5GHz), and DECT systems (base plus handsets) beat Wi-Fi for range and roaming at home or across large floors.Audio first. Unless video is essential, spend the budget on mics, speaker quality and noise reduction, rather than cameras.Poly’s Acoustic Fence and NoiseBlockAI are excellent on busy floors to block out open-plan office noise. Yealink’s Noise Cancellation is a strong alternative.Plan to grow. Standardise on a family that lets you add a sidecar, step up screen size or move from voice to video without retraining.The Best Desk Phones for Your OfficeBefore you read our reviews of nine models that stake a claim as the best desk phone for your business, let’s show you an at-a-glance comparison of our top three picks.

Yealink SIP-T46U: Best for Call CentresPrice: £90 to £175 ex-VAT (model/kit dependent) Call centres live or die on speed and visibility. The T46U earns this slot because it lets call centre agents see who’s free and transfer instantly, without hunting through on-screen menus, via programmable keys you can label for colleagues, queues, park orbits or speed-dials.When you add the EXP43 sidecar (an attachable module that gives you columns of extra keys), each key has a small light beside it (this is called a BLF or Busy Lamp Field). A green light means a person or queue is idle, while red means busy. That real-time status removes guesswork and cuts seconds from every transfer, which compounds over a day.The T46U also supports up to 16 SIP accounts, which is effectively a phone line or extension registration, and refers to how many lines (personal extension, hunt groups, overflow, etc.) it can handle without breaking.The dual Gigabit ports mean you can plug a PC “through” the phone without slowing its network connection, and PoE lets you power the phone from the switch (no wall adapter required). Two USB ports matter too: you can run a USB headset while leaving room by using a Wi-Fi or Bluetooth dongle, or for basic USB call recording if your platform supports it.

Meanwhile, the Yealink T34W is a better choice for a small budget if you can stomach only four lines and a smaller screen (not ideal for heavy live queues).Outside of Yealink, we’re fans of the Poly VVX 350 as a rock-solid midline phone, but a typical call floor wants far more at-a-glance keys than its six-line set. Likewise, Poly’s Edge E550 has appealing noise-cancelling, should you work in an open office environment, but lacks those one-press transfers we mentioned above.For those that need video capabilities on their hardware, the Poly CCX 700 and Cisco 8865 are great alternatives, too. But sales agents and other office desk workers are not likely to need camera hardware if they already have a laptop in front of them, and therefore, you’d be paying for features you won’t use.What VoIP phone systems does the Yealink SIP-T46U work with?RingCentral (T46U supported) Dialpad (T4U supported including T46U)GoTo Connect (supports Yealink)bOnline (T46U on list)8×8 (Yealink supported)Similar alternatives to the Yealink SIP-T46UYealink SIP-T43U: Cheaper monochrome screen, still takes EXP43; fewer “premium” cues than T46U. Price: Around £70 to £120 ex-VAT.Yealink SIP-T48U: 7″ touchscreen version if receptionists prefer a touch UI; same 16 lines and EXP50 module support. Price: Around £130 to £220 ex-VAT. 2. Yealink SIP-T34W: Best ValuePrice: £65 to £110 ex-VAT (retailer dependent) If you want a proper office phone without a big outlay, the T34W is the sensible starting point. It connects over built-in dual-band Wi-Fi, so you can place it wherever you have a strong signal and avoid extra cabling. The colour screen is smaller than pricier sets, but day-to-day actions (hold, transfer, redial) are still a tap or two away thanks to clearly labelled soft keys.Under the hood, you get up to four SIP accounts for your direct line, sales, support and after-hours. There’s also PoE for tidy power from the switch, Gigabit passthrough, so a PC can plug “through” the phone, and a USB port, too.The trade-off for the low price is deliberate: no touchscreen, no video and no attendant sidecar. But for single users, serviced offices or secondary desks, it covers the essentials with fewer compromises than most “budget” sets. Key Specifications of the Yealink SIP-T34WSpecDetails✓/✗Display2.4″ colour LCD (320×240) with backlight—Lines/SIP accountsUp to 4 (i.e. four lines/extensions)—Wi-Fi built inYes (dual-band 2.4/5 GHz)✅Bluetooth built inNot built in; use USB BT adapter for headsets◐TouchscreenNo❌Video cameraNo❌Sidecar/expansionNot supported (no attendant module)❌DECT cordlessWired desk phone (choose W73P for DECT)❌PoE (Power over Ethernet)Yes✅Gigabit passthroughDual-Gigabit (LAN + PC)✅USB ports1 (USB headset/config/optional BT)—Typical UK price£65 to £110 ex-VAT (retailer dependent)— How does the Yealink T34W compare with other office phones?Versus the T54W (best for small businesses), you’re saving money but giving up the larger tilting display, some shortcut depth and headroom (four lines versus 16). If you expect to add shared lines or grow headcount soon, the T54W is the safer bet.Against the T46U (best for call centres), the T34W isn’t aimed at heavy queue work: there’s no receptionist sidecar and fewer live keys, so you can’t build that big wall of presence indicators for one-press transfers. For agent floors, step up to T46U and EXP43.Compared with Poly VVX 350 (best for cubicle workers), the VVX gives you six physical line keys and a tougher “workhorse” feel for wired desks, but typically lacks built-in Wi-Fi. Choose the T34W when wireless deployment is the priority, but pick the VVX 350 when you’re standardising on Ethernet and want more live keys.Against Poly Edge E550 (Best for call quality), Poly’s noise-blocking is superb in loud, open offices, but you’ll pay more and may still need an accessory for Wi-Fi. And compared with DECT kits such as W73P, the T34W is for desk-based users, so DECT wins if you need to walk and talk across a larger site.What VoIP phone systems does the Yealink SIP-T34W work with?RingCentral (T34W listed on supported phones/shared lines pages)Dialpad (T34W on supported desk and room phones)GoTo Connect (T34W device guide; Yealink broadly supported)bOnline (T34W on compatibility list)8×8 (T34W device page/compatibility list)Similar alternatives to the Yealink SIP-T34WYealink SIP-T31W: Even cheaper Wi-Fi model with a black-and-white screen and fewer niceties; good for lobbies and secondary desks. Price: Often £50 to £70 ex-VAT.Poly Edge B30: Budget Poly option with Gigabit (no Wi-Fi built in); better fit for wired deployments that want a sturdier feel. Price: Typically similar or slightly higher than T34W. 3. Poly Trio C60: Best for Conference CallsPrice: £250 to £500 ex-VAT (retailer dependent) Meeting rooms need clear, natural conversation and zero faff. The Trio C60 delivers with full-duplex audio, Poly’s NoiseBlockAI to strip out keystrokes and HVAC hum and a 5″ touch screen that makes joining or expanding a meeting easy. USB, Bluetooth and IP connectivity mean you can run it as a classic SIP room phone or pair it with a laptop or mobile in seconds.Coverage is 360° and designed for medium rooms out of the box, with expansion microphones available for longer tables. So, if you want an audio-first table unit that’s proven across platforms and easy for guests to use, this is the safe choice for UK meeting spaces in 2025. Key Specifications of the Poly Trio C60SpecDetails✓/✗Display5″ colour capacitive touch (720×1280)✅Lines/SIP accountsRoom endpoint (SIP/IP)—Wi-Fi built inSupported on current SKUs (check firmware/profile)✅Bluetooth built inYes (pair mobile/laptop for audio)✅TouchscreenYes✅Video cameraNo (audio-first conference phone; pairs with Poly video kits)❌Sidecar/expansionSupports expansion microphones for larger rooms◐DECT cordlessNo (table-top unit)❌PoE (Power over Ethernet)Yes✅Gigabit passthroughNo PC passthrough❌USB ports2 (USB-A + micro-B for device/audio use)—Typical UK price£250 to £500, depending on retailer—How does the Poly Trio C60 compare with other office phones?Compared with desk sets such as the Yealink T46U (best for call centres) or Poly VVX 350 (best for cubicle workers), Trio C60 is engineered for room acoustics: full-duplex audio, smarter noise blocking and expansion mic options that desk handsets can’t match. If your team regularly gathers around a single speaker, this is the right tool.If you specifically need on-device video at a desk, look at Cisco 8865 or Poly CCX 700. They both add cameras and bigger touch UIs for one-to-one video. For pure audio in huddle to mid-sized rooms, Trio C60 stays cleaner and typically cheaper than a full video bar.Versus the Yealink CP965, the Trio C60 leans on Poly’s mature noise controls and ultra-simple “one-touch join”. CP965 counters with Android UI and Yealink’s wider CP family.Both are excellent, but we recommend choosing Poly if you want best-in-class noise handling and cross-platform familiarity, and Yealink if you’re standardising on Yealink endpoints (many VoIP companies have a Yealink preference, or exclusivity in the case of bOnline).What VoIP phone systems does the Poly Trio C60 work with?RingCentral (SIP room phone; Poly devices widely supported)GoTo Connect (Poly conference phones supported)8×8 (Poly Trio C60 listed/sold)Dialpad (SIP provisioning; confirm firmware profile)Vonage/NBC (standard SIP, but check approved firmware with provider)Similar alternatives to the Poly Trio C60Yealink CP965: Android touch UI and 360° 6m pickup; strong value in Yealink-standardised estates. Price: Typically £600 to £800 ex-VAT.Cisco 8832: Business-class conference phone with 360° coverage; good fit for Cisco shops and larger rooms with optional mics. Price: UK pricing varies by kit. 4. Poly CCX 700: Best for Video CallsPrice: £230 to £460 ex-VAT (bundle/retailer dependent) If you want real face-to-face calling at the desk without juggling a laptop, the CCX 700 keeps it elegant. A bright 7″ touchscreen and an integrated camera mean you can place or receive a video call as easily as a voice call, with no clip-on webcams or USB hubs to fuss over. Poly’s NoiseBlockAI and Acoustic Fence cancel out background clatter so the far end hears a clean feed.It connects how modern offices actually work: Wi-Fi and Bluetooth are built in for flexible placement and wireless headsets, while dual-Gigabit Ethernet and PoE keep wired deployments neat. Under the hood, multiple SIP registrations (think: several lines/extensions on one set) let execs and team leads juggle a direct line alongside shared sales/support or an overflow hunt group.Compared with sticking a webcam on a standard phone, the CCX 700’s integrated camera, larger touch UI, and tuned audio make video feel natural. That’s why it’s a favourite for exec desks, reception pods that host VIP calls and anyone who has regular one-to-ones with clients. Key Specifications of the Poly CCX 700SpecDetails✓/✗Display7″ colour capacitive touchscreen✅Lines/SIP accountsUp to 24 (multiple lines/extensions)—Wi-Fi built inYes (dual-band)✅Bluetooth built inYes (headsets/mobile pairing)✅TouchscreenYes✅Video cameraIntegrated camera (onboard)✅Sidecar/expansionNo receptionist sidecar (use BLF/soft keys)❌DECT cordlessNo (desk phone)❌PoE (Power over Ethernet)Yes✅Gigabit passthroughDual-Gigabit (LAN + PC)✅USB ports2 (USB-A + USB-C for accessories/storage)—Typical UK price£230 to £460 ex-VAT (bundle/retailer dependent)—How does the Poly CCX 700 compare with other office phones?Against the Poly Trio C60 (best for conference calls), the CCX 700 is a desk device built for one-to-one video and voice. The Trio is a room device focused on shared, audio-first meetings. If your users sit at a desk and speak to clients on camera, pick CCX, but if they gather around a table, pick Trio.Compared with Cisco 8865 (best premium), Cisco’s set pairs beautifully with Cisco estates and offers Key Expansion Module (KEM) expansion, but the Poly CCX 700 is tidier for “video-at-the-desk”, with an integrated camera and Poly’s standout noise controls. If your IT stack leans Cisco, the 8865 makes sense. Otherwise, the CCX feels simpler to deploy broadly.Versus the Yealink VP59 or SIP-T58W (Pro) and CAM50, those Yealink sets often undercut CCX on price and still deliver strong picture quality. But the CCX counters with cleaner audio in open offices and a more unified “all-in” design.If you don’t need video at all, a standard set like the Yealink SIP-T54W (Wi-Fi/Bluetooth built in) or Yealink SIP-T46U and EXP43 (button-dense transfers) will save budget.What VoIP phone systems does the Poly CCX 700 work with?RingCentral (Poly CCX series supported/sold)GoTo Connect (Poly desk phones supported; CCX series provisioned via SIP)8×8 (Poly endpoints commonly supported; confirm firmware profile)Vonage (Poly endpoints supported on UCaaS; check approved firmware)NBC (Poly devices supplied on BroadSoft-based service)Dialpad (SIP provisioning supported; confirm CCX profile with admin)Similar alternatives to the Poly CCX 700Cisco 8865: Premium video desk phone with Cisco ecosystem polish and KEM expansion; ideal for Cisco-centric estates. Price: Typically £300 to £530 ex-VAT, depending on SKU/stock.Yealink VP59: 8″ touch with 1080p camera; often sharper on price while keeping strong video quality. Price: Commonly in the £300 to £450 ex-VAT range. ▶ Read more: The Best Cloud Phone Systems for UK Businesses 5. Yealink SIP-T54W: Best for Small BusinessesPrice: £90 to £160 ex-VAT (retailer dependent) For small teams moving fast or working across serviced offices, the T54W keeps things simple: it joins your network over Wi-Fi straight away, so you can put a phone where it’s actually needed rather than where the nearest Ethernet socket happens to be. Bluetooth is built in too, which makes pairing a wireless headset painless and keeps desks uncluttered.Day to day, the tilting colour display is easy on the eyes, and soft keys adapt to what you’re doing, so common actions take fewer presses. If you do have Ethernet at the desk, dual Gigabit ports let a PC plug “through” the phone without losing speed, and PoE means no separate power brick underfoot.Capacity-wise, the handset supports up to 16 SIP accounts, giving room for an owner/manager’s extension, plus shared sales and support lines, after-hours routing and more. A single USB port covers a wired headset, quick configuration backups or basic recording (where your platform allows).

That headroom matters once you add shared lines or night service.Compared with the T46U (best for call centres), this is about wireless convenience rather than button density. You won’t get a wall of BLF keys or sidecar lights for rapid transfers, but you also won’t have to run new cables to every desk.The Poly VVX 350 (best for cubicle workers) is a superb wired workhorse, yet it doesn’t include Wi-Fi/Bluetooth as standard. We’d say the T54W is cleaner when you’re standardising across mixed desk locations or serviced offices. You’ll also avoid paying for features you may never use, unlike video-equipped sets such as Poly CCX 700 or Cisco 8865.And while DECT kits such as the W73P are ideal for roaming around a building, most small offices prefer a desk phone with a bigger screen and easier shared-line handling.What VoIP phone systems does the Yealink SIP-T54W work with?RingCentral (T5 series supported)Dialpad (T5 series supported)GoTo Connect (supports Yealink)bOnline (T54W on list)8×8 (Yealink supported)Similar alternatives to the Yealink SIP-T54WYealink SIP-T57W: Bigger 7″ touchscreen and a more “executive” feel; keeps Wi-Fi/Bluetooth and supports EXP50. Price: Usually £170 to £230 ex-VAT.Poly Edge E350: Modern UI with Poly’s NoiseBlockAI/Acoustic Fence; many SKUs include Wi-Fi/Bluetooth. Strong audio in open spaces, typically pricier than T54W. Price: Often £190 to £230 ex-VAT. 6. Poly Edge E550: Best for Call QualityPrice: £90 to £200 ex-VAT (retailer/bundle dependent) If your office is lively with open-plan chatter, clacking keyboards, and air conditioning hums, the Edge E550 keeps voices cleaner than most. Poly’s Acoustic Fence creates a “pickup zone” around the speaker and suppresses sound outside it, while NoiseBlockAI mutes constant background noise between phrases. The result is fewer “sorry, say that again?” moments and less fatigue on long calls.It’s also a practical daily driver: a bright 5″ colour display with status light bar, 12-line keys (with pagination for additional lines), and modern radios (Wi-Fi and Bluetooth 5.0) built in for flexible placement and wireless headsets. Dual-Gigabit Ethernet and PoE keep wired desks neat, and an expansion module option lets reception or team leads add more at-a-glance contacts when needed.Depending on the platform, the E550 can show many more contacts than the 12 physical keys by paging through virtual keys, so you aren’t boxed in as the team grows. Key Specifications of the Poly Edge E550SpecDetails✓/✗Display5″ colour IPS LCD with status light bar—Lines/SIP accounts12 line keys; supports additional lines via pagination (platform-dependent)—Wi-Fi built inYes (2.4/5 GHz)✅Bluetooth built inYes (Bluetooth 5.0 for headsets/mobile pairing)✅TouchscreenNo (physical keys + soft keys)❌Video cameraNo (voice-first desk phone)❌Sidecar/expansionSupports Poly Edge E Expansion Module (for more contacts/BLF)✅DECT cordlessNo (choose a DECT kit like W73P/Rove for roaming)❌PoE (Power over Ethernet)Yes✅Gigabit passthroughDual-Gigabit (LAN + PC)✅USB ports1 USB-C (headset/media/expansion module)—Typical UK price£90 to £200 ex-VAT (varies by retailer/bundle)—How does the Poly Edge E550 compare with other office phones?Against Yealink SIP-T46U (best for call centres), the E550 won’t match the T46U and sidecar for sheer “one-press transfer” density, but it will sound cleaner in noisy spaces thanks to Acoustic Fence and NoiseBlockAI. If your priority is audio clarity over maximum keys, the E550 is the safer bet.Compared with the Yealink T54W (best for small businesses), both have Wi-Fi/Bluetooth for cable-light rollouts. The T54W offers a tilting screen and Yealink ecosystem tooling, while the E550 gives you Poly’s noise suppression and a more prominent status light bar, which is useful on a busy floor.If you’re considering video at the desk, Poly CCX 700 and Cisco 8865 add cameras and larger touch UIs, whereas the E550 purposely stays voice-first to keep costs down. For wired, midline durability, a Poly VVX 350 remains a bargain, but it lacks the E550’s modern radios and noise controls.What VoIP phone systems does the Poly Edge E550 work with?RingCentral (Poly Edge E500/E550 listed on certified/supported phones)GoTo Connect (Edge E series (including E550) device page and feature support)Dialpad (Edge E family shown on supported desk and room phones (with setup/provisioning guides))Vonage (Edge E series covered on Vonage support; SIP compatible on UK UC service)8×8 (Poly endpoints broadly supported (confirm firmware/profile with your tenant))NBC (BroadSoft-based service supplying Poly devices; check approved firmware)Google Voice (Poly remains the only vendor with certified desk phones for Google Voice; recent updates indicate Edge E family support in many tenants)Similar alternatives to the Poly Edge E550Poly VVX 350 (OBi Edition): Wired midline workhorse with six physical line keys; great value for Ethernet-first desks and Google Voice tenants. Price: Often under £100 ex-VAT (new/refurb market).Yealink T58W (Pro): Premium wideband audio with Yealink Noise Cancellation; adds optional CAM50 camera if you want occasional video. Price: Typically higher than E550 but below most full video sets. 7. Cisco 8865: Best Premium (Money No Object)Price: £300 to £530 ex-VAT (SKU/stock dependent) When you want a desk phone that feels like a flagship, the Cisco 8865 is the executive choice, offering a polished build, HD video on tap and deep expandability.A crisp widescreen display sits above a tidy cluster of hard keys, while the integrated 720p camera, dual-Gigabit Ethernet, and Bluetooth support make daily calls (and on-the-spot video) effortless. It’s also one of the few video desk sets that plays nicely with KEM expansion modules, so reception and exec assistants can keep dozens of contacts and BLF statuses at their fingertips, without giving up the premium handset.This is a wired, boardroom-grade device: power it with PoE, pass a PC through the second Gigabit port, and add one or more 8800-series key expansion modules if you need a full attendant console. If you’re already a Cisco-leaning estate, or you just want the most refined desk experience, the 8865 is the set that feels money-no-object without drifting into meeting-room hardware territory.

Yealink counters on price, however, so if you want 1080p and can live without Cisco’s modules, VP59 is strong value.If you don’t need camera hardware, a voice-first set will save budget: Poly Edge E550 for best-in-class call clarity in noisy spaces, or Yealink T46U and EXP43 if one-press transfers and a wall of BLF is the priority.What VoIP phone systems does the Cisco 8865 work with?RingCentral (supports Cisco 8800-series MPP/3PCC models (confirm SKU))GoTo Connect (Cisco SIP phones supported; provision via admin portal)8×8 (Cisco SIP endpoints commonly supported (check firmware profile))Vonage (Cisco devices supported on UCaaS; confirm approved firmware)NBC (BroadSoft-based service supplying Cisco/Poly/Yealink phones)Dialpad (SIP provisioning possible; verify 8865 profile with admin)Similar alternatives to the Cisco 8865Poly CCX 700: Integrated camera, 7″ touch, superb noise controls; a simpler “video-at-the-desk” experience.

Yealink W73P: Best for Home Office UsePrice: £50 to £130 ex-VAT per kit (retailer dependent) For a home office, cordless convenience beats cable runs. The W73P pairs a compact W70B DECT base with a W73H handset, so you can walk and talk around the house without dropouts or headset juggling. DECT (a radio standard for cordless phones) is designed for long range and steady voice quality, which makes it more reliable than Wi-Fi calling when you’re moving between rooms or floors.The base can register multiple SIP accounts that can handle several concurrent calls at once, so you can keep a personal extension plus shared lines (like support or after-hours) on the same system. The handset’s battery is built for all-day use, and the charging cradle keeps things tidy on the desk. Because the base uses PoE, you can power it directly from your router/switch with a single cable.Compared with a desk set, you give up a large screen and hordes of keys, but you gain mobility, quiet operation and fewer cables, which is ideal for spare rooms and hybrid setups.

In other words, better if your “office” is a bedroom or kitchen table.Compared with the T46U and EXP43 (best for call centres), a cordless kit won’t match the speed of one-press transfers and BLF lights, but it’s much more practical for moving around the house.If you’re considering premium voice clarity, the Poly Edge E550 filters background noise in busy open spaces, say if you have kids or work in an open-plan kitchen-living room, but it’s a wired desk set. For meeting tables, the Poly Trio C60 or Yealink CP965 are room phones, which are great when several people speak, but unnecessary for one-person home setups.What VoIP phone systems does the Yealink W73P work with?8×8 (W73P/W70B documented and widely deployed)GoTo Connect (Yealink DECT kits supported via SIP)Dialpad (Yealink wireless/DECT supported; confirm firmware profile)bOnline (Yealink cordless kits sold/supported)Vonage/NBC (standard SIP support; check approved firmware for your tenant)RingCentral (supported on many accounts as BYOD SIP; confirm on your plan/firmware before bulk orders)Similar alternatives to the Yealink W73PPoly Rove B2 + Rove 30/40 handset: Enterprise-grade DECT with optional repeaters and rugged, antimicrobial handsets. Price: Typically pricier than W73P but great for larger homes/outbuildings.Gigaset N670 IP PRO + S700H PRO: Flexible SMB DECT base with pro-grade handset; excellent battery life and handset feel. Compatibility is via standard SIP, but check with your provider. Price: Typically £500 to £550 for five handsets with POE (Gigaset N670 IP PRO) 9. Poly VVX 350 (OBi Edition): Best for Cubicle WorkersPrice: £135 to £185 ex-VAT (retailer dependent) For classic, wired desks that field a steady flow of calls, the VVX 350 is the no-drama workhorse. You get six dedicated line keys with status lights, ideal when you park calls, monitor colleagues or juggle shared lines, plus hard keys for hold, transfer, mute and speaker, so common actions stay muscle-memory fast. The colour screen is compact but clear, and the handset/speaker delivers the wideband “Poly sound” people trust for long days on the phone.Like other office phones on this page, you also have dual-Gigabit Ethernet, PoE and a USB port. It’s not flashy (no touchscreen, no camera), but it’s a solid choice to sit on a desk and just get on with it, shift after shift.

If you need dozens of at-a-glance BLF lights and one-press transfers, pick the T46U bundle. If you want a tough, clean six-line desk set, the VVX is simpler and usually cheaper.Compared with the Yealink T54W (best for small businesses), both make great daily drivers. The T54W wins on integrated Wi-Fi/Bluetooth and a tilting display; the VVX 350 wins on straightforward hard keys and broad availability at sharp prices for Ethernet-first offices.Against the Poly Edge E550 (best for call quality), E550 adds modern radios and advanced noise suppression for noisy floors. If your space is quiet and budgets are tight, VVX 350 is a terrific value proposition. But if background noise is constant, E550 is worth the premium.If you need on-device video, step to Poly CCX 700 or Cisco 8865. And if you want to walk and talk, a DECT kit like Yealink W73P beats any wired desk phone for mobility.What VoIP phone systems does the Poly VVX 350 work with?RingCentral (VVX 250/350/450 widely supported)GoTo Connect (VVX x50 series provisioned via admin portal)Vonage (VVX family supported on UK UCaaS)Dialpad (use VVX x50 OBi Edition firmware for best support)8×8 (Poly VVX commonly supported (confirm profile))NBC (BroadSoft-based service supplying Poly phones)Google Voice (certified path is VVX x50 OBi Edition; confirm model/firmware in the Admin console)Similar alternatives to the Poly VVX 350Poly VVX 450: Doubles the lines to 12 and supports the EM50 expansion module, which is better for supervisors or reception-adjacent desks. Price: Typically £20 to £80 more than VVX 350 in UK channels.Yealink T43U: Six-line, monochrome-screen alternative with sharp pricing; supports the EXP43 sidecar if you need more keys. Price: Usually around £70 to £120 ex-VAT. ▶ Looking for software too?: Discover the best virtual phone number apps Buying Guide: Picking the Perfect Desk PhoneBelow, we run through why the Big Switch Off means you probably need to upgrade your desk phone hardware, what VoIP integration with desk phones tends to look like and what sort of features the best desk phones offer.The Big Switch Off and desk phone compatibilityThe phasing out of traditional PSTN (Public Switched Telephone Network) and ISDN (Integrated Services Digital Network) services, known as the ‘Big Switch Off’, is set to occur in January 2027.This transition means traditional landline technology will need to be replaced by hardware equipped for VoIP technology.With the clock counting down towards that date, businesses need to begin assessing their current telephone needs, what capabilities they may require in the future and what hardware can help facilitate those needs.Desk phones and VoIPFuture-proofed desk phones that integrate seamlessly with VoIP tend to offer more advanced capabilities than traditional models. That includes high-definition audio quality, multi-line management and integration with other business tools, such as CRM software and email platforms.In many ways, managing and maintaining VoIP systems is easier than traditional landlines. It offers cloud-based options that can quickly update your calling infrastructure with new features or other enhancements, without needing to replace your hardware entirely.Having said that, we’ve found that certain VoIP providers work best with specific hardware. For instance, bOnline – one of our top-rated business VoIP providers for medium-sized organisations – works primarily with Yealink desk phones. You need to make sure that any hardware you purchase can be fully integrated into your VoIP system, and vice versa.Desk phone featuresWith so many options out there, choosing the right phone system can feel overwhelming – so it helps to have a list of must-haves to look out for. When it comes to office phones, our advice is to make sure you get:An auto-attendant: This is an automated system that directs callers to the right member of staff or team, based on their reason for calling your company. Some also keep callers on hold and play personalized messages to keep them engaged until someone can pick up.Speed dial: The ability to contact particular extensions, partners and clients with the touch of a button just makes things so much smoother!Conference calling: A phone system that lets multiple people jump on the same call opens up a whole new world of remote meetings and cross-team collaboration. (If long-distance meetings are a mainstay for your team, check out our list of the best conference phones.)Voicemail: If a customer can’t get hold of you for any reason, giving them the option to leave a message shows that you still want to hear from them. Plus, you’ll miss fewer leads. Some phone systems can even automatically forward a recording or transcript of each voicemail to your email inbox, so nothing slips through the cracks.A good LCD display screen: When your phone rings, being able to check caller ID at a glance before picking up means you’re better prepared for the call. Plus, handy system alerts and missed call/voicemail notifications are more difficult to miss on a quality screen. How We Found the Best Office Phone SystemsAt Expert Market, we spend time researching, testing and evaluating providers we write reviews about. This typically consists of conducting market research to narrow down the software that's really worth digging into a little more and then assessing it against a range of research criteria.Our decision-making criteria with assessment weightingInformed by readers and businesses we speak to regularly, as well as our own experiences using major VoIP platforms, we designed a research framework to assess each VoIP provider plan. It consists of eight overarching assessment categories, each designed to answer a specific question a buyer might have.Which VoIP service offers the best call handling features for UK businesses?Call management (25%): We assessed features like call routing, queues, custom greetings, voicemail screening and spam call blocking to see how well each provider handles inbound traffic.Can this platform support internal communication across remote or hybrid teams?Communication channels (20%): We looked at the availability of tools like video conferencing, team messaging, SMS and mobile app functionality.Will this system help me onboard and train staff effectively?Training features (20%): We tested tools for live coaching (e.g. call whisper/barge), call recording and performance dashboards — crucial for service and sales teams.Is the pricing clear and competitive for small and medium businesses?Pricing (10%): We reviewed subscription tiers, user discounts, setup fees and whether unlimited minutes are included or capped.Will this VoIP system work with the software we already use?Software integrations (10%): We checked how well each provider integrates with platforms like Salesforce, HubSpot, Zendesk, Google Workspace and Microsoft Teams.Can we keep using our existing phones and hardware?Hardware integrations (5%): We reviewed compatibility with desk phones, speaker systems and headsets from major brands.What level of customer support is available if we run into issues?Customer support (5%): We tested the availability of live chat, phone and email support, as well as help centres and user communities.How secure is this system for business use?Security options (5%): We assessed features like multi-factor authentication (MFA), encryption and compliance with UK data protection laws (e.g. GDPR). Verdict There we have it. Nine standout office phones for UK businesses in 2025, covering call centres, small teams, conference rooms, video-first desks, home offices and more. This is a balanced shortlist from Yealink, Poly and Cisco, each chosen for a specific job rather than headline specs.We have retired the old number one Cisco 7841 pick for 2025. In its place, the lineup now reflects what buyers actually need today: fast transfers with Yealink T46U and EXP43, cable-light rollouts with Yealink T54W, room audio with Poly Trio C60, desk video with Poly CCX 700, premium polish with Cisco 8865, rock-solid midline sets like Poly VVX 350, and cordless freedom at home with Yealink W73P.The right choice still depends on your workflow. Confirm that your model is supported by your provider, check the exact firmware or profile, and size the phone to your roles.As a rule of thumb, teams on hunt groups or overflow lines should aim for six to 16 lines, while solos and secondary desks can work with four. If you transfer a lot of calls, choose a handset that supports a sidecar so BLF keys show who is free or busy at a glance.Want help narrowing it down for your setup?
