IP Phones Price Comparison
Compare 353 IP phones from Yealink, Poly, Cisco and more. Find the best price across UK retailers, from basic desk phones to Microsoft Teams-certified models.
IP phones occupy a curious middle ground in the modern office: technically mature, yet still evolving fast. The shift towards Microsoft Teams and cloud-hosted PBX systems has reshuffled the market considerably — brands like Yealink and Poly now dominate where Cisco once had near-total control, and the price gap between a capable entry-level handset and a full-featured executive phone has never been wider. We track 353 models across this category, with prices ranging from 50 £ for basic SIP handsets up to 150 £ for high-end video conferencing units.
What stands out when you look at the data is how competitive the mid-range has become. Grandstream Networks, for instance, averages well below the category mean whilst offering 4- and 12-line models that would have cost significantly more a few years ago. Yealink sits slightly higher on average, but their Teams-certified MP series justifies the premium for businesses already running Microsoft 365. Cisco remains the outlier — their average price is roughly double the category median, which makes sense only if you're locked into a Cisco Unified Communications environment.
Connectivity is where the real differentiation happens today. PoE (Power over Ethernet) has become almost standard, eliminating the need for a separate power adaptor and simplifying desk deployments. Wi-Fi support, once a luxury, now appears on models like the Yealink SIP-T34W and the Grandstream WP816 at very accessible price points. For businesses considering a broader telephone upgrade, it's worth mapping out your cabling infrastructure before committing to a wired-only model.
One thing we'd flag: the Microsoft Teams certification ecosystem is genuinely worth paying attention to. Teams-native phones — as opposed to generic SIP phones configured to work with Teams — offer a noticeably smoother experience, with native call controls, presence indicators, and calendar integration baked in. If your organisation is on Teams, the Yealink MP and Poly CCX ranges are the obvious starting points. If you're running an open-source PBX like Asterisk or FreePBX, Grandstream and Snom offer excellent compatibility at more modest prices.
How to Choose the Right IP Phone for Your Business
Not all IP phones are created equal — and the wrong choice can mean a handset that's incompatible with your PBX, lacks the lines your team needs, or simply feels cheap after six months of daily use. The market spans from sub-58 £ SIP basics to executive touchscreen units well over 125 £, so narrowing down what actually matters for your setup is the first step.
SIP Lines and Simultaneous Calls
This is the single most important spec to get right. A 2-line phone suits a single user who occasionally needs to hold one call while answering another. Receptionists, call handlers, and team leads typically need 4–6 lines minimum. If you're equipping a busy front desk or a small contact centre, look at 8- to 12-line models like the Grandstream GXP2170. Getting this wrong means users constantly hitting a busy signal on their own handset — frustrating and surprisingly common in under-specified deployments.
Platform Compatibility: Teams, SIP, or Both?
This is the fork in the road. If your business runs Microsoft Teams, a Teams-certified phone (Yealink MP series, Poly CCX) will give you native call controls, presence, and calendar — no workarounds needed. If you're on a SIP-based PBX (Asterisk, 3CX, FreePBX, or a hosted provider), a standard SIP phone from Grandstream, Snom, or Fanvil will serve you better and cost less. Avoid the temptation to buy a Teams phone and force it onto a generic SIP trunk — it rarely ends cleanly.
PoE vs. External Power Adaptor
Power over Ethernet (PoE, 802.3af or 802.3at) lets the phone draw power directly from the network switch, eliminating a power adaptor at every desk. For a 10-person office, that's 10 fewer plugs and 10 fewer cables to manage. Most mid-range and above phones now support PoE, but double-check your switch has PoE ports available — or budget for a PoE injector. Entry-level models under 58 £ sometimes ship without PoE support, which is worth confirming before ordering in bulk.
Wired Ethernet vs. Wi-Fi Deployment
Ethernet remains the gold standard for call quality and reliability — jitter and packet loss are the enemies of clear voice, and a wired gigabit connection eliminates both. That said, Wi-Fi support (802.11ac or better) is genuinely useful for hot-desking environments, open-plan offices where cabling is impractical, or warehouse settings. Models like the Yealink SIP-T34W and Grandstream WP816 handle Wi-Fi well. Just ensure your wireless infrastructure is solid — a patchy Wi-Fi signal will produce worse call quality than any codec choice.
Screen Size and Programmable Keys
For users who live on the phone — receptionists, PAs, sales teams — a larger colour TFT display and a generous bank of programmable keys make a real difference to daily productivity. Being able to see 10 colleagues' presence status at a glance, or speed-dial a key account with one button, saves minutes per call that add up fast. For occasional users or back-office staff, a basic LCD with 4 programmable keys is perfectly adequate. Don't over-spec here if the phone will sit mostly idle.
Audio Quality: Codecs and Wideband Support
HD voice (G.722 or Opus codec) makes calls noticeably clearer — less fatigue, fewer misheard words. Most phones above 58 £ support wideband audio, but it only works if both ends of the call and your PBX support it too. For internal calls within a modern hosted PBX, this is usually a given. For calls to PSTN landlines or mobiles, you'll fall back to G.711 narrowband regardless. SRTP and TLS encryption are worth checking if your calls carry sensitive information — most business-grade phones include both, but budget models sometimes omit TLS.
- Entry-level — the basics done adequately (From 50 £ to 58 £) : Grandstream GRP2604 and similar 2–3 line SIP phones sit here. Functional, PoE often absent, LCD displays, limited programmable keys. Fine for occasional users, back-office staff, or a first VoIP deployment on a tight budget. Don't expect HD voice or Teams integration at this end.
- The sweet spot for most businesses (From 58 £ to 89 £) : This is where the best value lives. Grandstream GXP-2130/2140, Yealink SIP-T34W, Snom entry models — solid 3–4 line phones with PoE, HD voice, colour displays, and decent build quality. Suitable for the majority of office workers. We'd start here for any deployment of 5 or more handsets.
- For power users and team leads (From 89 £ to 125 £) : Yealink MP54/MP56 Teams phones, Poly CCX 600, Auerswald COMfortel D-110. Larger screens, more programmable keys, Teams or Zoom certification, Bluetooth headset support. Worth the step up for receptionists, managers, or anyone handling high call volumes. Yealink's MP range is particularly strong here.
- Executive and specialist deployments (Over 125 £) : Cisco, AGFEO, Unify, and Mitel occupy this tier. Often includes video calling, large touchscreens, extensive expansion module support, and enterprise-grade security. Cisco's premium is only justified if you're running Cisco Unified Communications Manager — otherwise you're paying for brand, not features. AGFEO and Unify make more sense in specific European enterprise environments.
Top products
- Grandstream Networks GXP-2140 IP phone Black 4 lines TFT (Grandstream Networks) : Excellent all-rounder for the price — 4 SIP lines, colour TFT display, and solid build quality make this the default recommendation for most office workers. Not glamorous, but hard to fault at this price point.
- Yealink SIP-T34W IP phone Black 4 lines LED Wi-Fi (Yealink) : The Wi-Fi support sets this apart from wired-only rivals at a similar price. Ideal for open-plan offices or hot-desking setups where running Ethernet to every desk isn't practical. LED display is functional rather than impressive.
- Grandstream Networks GXP2170 IP phone Black 12 lines LCD (Grandstream Networks) : The go-to choice for receptionists and power users who need to manage multiple lines simultaneously. 12 SIP accounts is overkill for most, but for a busy front desk it's exactly right. Grandstream's pricing here is genuinely competitive against Yealink equivalents.
- POLY CCX 600 Business Media Phone for Microsoft Teams and PoE-enabled (POLY) : One of the strongest Teams-certified desk phones on the market — large touchscreen, PoE, and a genuinely polished Teams experience. Worth the premium if you're on Microsoft 365; a poor choice if you're not, as it's firmly locked to that ecosystem.
- Yealink W76P IP phone Grey 20 lines TFT (Yealink) : A DECT base station and handset bundle capable of supporting up to 20 lines — unusually versatile for a wireless system. The right pick for businesses that need cordless mobility without sacrificing line capacity. Overkill for a single user, but excellent for shared spaces.

Frequently Asked Questions
What is the difference between a SIP phone and a Teams-certified IP phone?
A SIP phone uses the open Session Initiation Protocol and works with virtually any PBX or hosted VoIP provider, whilst a Teams-certified phone runs Microsoft's own firmware and is designed specifically for Teams Phone calls. The practical difference is significant: Teams-certified models (like the Yealink MP series or Poly CCX range) give you native presence indicators, one-touch meeting join, and calendar integration — things a generic SIP phone configured for Teams simply cannot replicate cleanly. If your organisation is committed to Microsoft 365, the Teams-native route is worth the extra cost.
Do I need PoE switches to deploy IP phones across an office?
Not necessarily, but PoE makes deployment considerably cleaner. Without PoE, each phone needs its own power adaptor and a nearby mains socket — manageable for a handful of handsets, but a real headache at scale. Most mid-range IP phones support PoE (802.3af), so if your network switches already have PoE ports, you're set. If not, a PoE injector per phone is a low-cost workaround, though a PoE switch is the tidier long-term solution for offices of 10 or more.
How many SIP lines do I actually need?
For a typical office worker who handles one call at a time, 2–3 lines is sufficient. Receptionists and team leads who juggle multiple calls simultaneously should look at 4–6 lines. High-volume environments — call centres, busy front desks — benefit from 8–12 lines, as found on models like the Grandstream GXP2170. A common mistake is under-specifying lines for reception staff, who then find themselves unable to transfer a call without dropping another.
Are cheap IP phones worth buying, or should I avoid them?
It depends entirely on the use case. A sub-58 £ SIP phone is perfectly adequate for a back-office employee who takes a handful of calls per day — the call quality will be fine and the features sufficient. Where budget phones let you down is in high-use scenarios: the build quality degrades faster, programmable keys are limited, and HD voice or encryption may be absent. We'd avoid the very cheapest models for receptionists or anyone on the phone for more than two hours a day. The sweet spot for most users sits between 58 £ and 89 £.
Can I use an IP phone with any VoIP provider or PBX?
Most SIP-based IP phones are compatible with any SIP-compliant PBX or hosted VoIP provider — Asterisk, 3CX, FreePBX, RingCentral, and most UK business VoIP services all work with brands like Grandstream, Yealink, Snom, and Fanvil. The exception is Teams-certified phones, which are locked to Microsoft's platform, and Cisco phones, which are optimised for Cisco's own Unified Communications Manager. Always check the interoperability list on your PBX provider's website before purchasing in bulk.
What does SRTP and TLS mean on an IP phone, and do I need it?
SRTP (Secure Real-time Transport Protocol) encrypts the audio stream of your calls, whilst TLS (Transport Layer Security) encrypts the signalling — essentially the call setup instructions. Together, they prevent eavesdropping on VoIP calls. For most small businesses, the risk is low, but for legal, financial, or healthcare environments handling sensitive conversations, both are essential. The good news is that most business-grade IP phones above 58 £ include SRTP and TLS 1.2 as standard — just confirm it's enabled in the phone's configuration.
Which IP phone brands are most reliable for UK business deployments in 2026?
Yealink and Grandstream Networks are the two most consistently reliable choices for UK SME deployments, offering broad PBX compatibility, regular firmware updates, and strong value. Poly (formerly Plantronics/Polycom) is the go-to for Teams and Zoom environments. Snom has a loyal following among IT resellers for its open standards and build quality. Cisco remains excellent but commands a significant price premium that's only justified in full Cisco UC environments. Fanvil is worth considering for budget-conscious deployments where feature breadth matters more than brand recognition.
