What a cloud phone system really costs
| Team size | Entry plan (~$15/user/mo) per year | Mid plan (~$25-30/user/mo) per year |
|---|---|---|
| 5 users | $900 | $1,500 – $1,800 |
| 20 users | $3,600 | $6,000 – $7,200 |
| 50 users | $9,000 | $15,000 – $18,000 |
Those are the plan costs. Budget for a few extras so the first bill is not a surprise. Taxes and regulatory fees usually add roughly $3 to $6 per user per month and are rarely in the headline price. International calling is metered or a paid add-on on most systems, except dedicated global players like 8×8 and Ringover. Extra numbers, toll-free numbers and SMS beyond the included allowance cost more. Number porting is almost always free and takes a few business days. Many team-focused tools (Aircall, JustCall) carry a minimum seat count, and the lowest advertised tier often omits features most businesses need.
The 16 best business phone systems in detail
Each provider below is scored against the same rubric. We verify pricing and documentation; we do not run scripted test calls, and we say so plainly in our methodology.
1. Nextiva – Best all-round small business phone system
Nextiva is the pick most small businesses should start with. It bundles voice, video meetings, team messaging and an auto attendant into one app, and it wins our highest marks for call reliability (9.0) and support (9.5) – the two things an owner feels first. Pricing runs from about $15 per user per month on annual billing at the entry tier, so a five-person office lands near $900 a year and a 20-person team near $3,600, before taxes and regulatory fees. Texting, a mobile and desktop app, and a basic auto attendant are included; international calling is a metered add-on. Integrations cover the CRMs most SMBs run (HubSpot, Salesforce, the common helpdesks) without a developer. The honest drawback is that the very cheapest tier limits some of the collaboration and analytics features, so growing teams usually sit a tier up. If you just want a dependable phone system that your staff can run without IT, this is it.
2. RingCentral – Best cloud phone system for scaling and enterprise
RingCentral is the most complete cloud phone system on this list, and it scores top of the field on integrations (9.5) – its marketplace is the widest here, which is why larger and faster-scaling teams standardise on it. Plans verify at roughly $20 per user per month on annual billing for Core, $25 for Advanced and $35 for Ultra; monthly billing runs about $10 more per seat, so 20 users on Core land near $4,800 a year on annual terms. You get unlimited US and Canada calling, texting, RingCentral video, a multi-level auto attendant and strong analytics. International is bundled on Ultra or added per seat. The trade-offs are real: setup and admin (7.0) are heavier than a startup tool, and the bill grows with add-ons and regulatory fees, so read the order form. For a company that needs global coverage, deep CRM ties and room to grow, it earns the price.
3. Dialpad – Best for AI features and coaching
Dialpad leads the field on features (9.5) because AI is built into every call rather than bolted on: live transcription, automatic summaries, sentiment and real-time agent coaching come standard, and its AI receptionist can answer and route callers. Seat pricing starts around $15 per user per month on annual billing, but note that Dialpad now prices its AI Agent and contact-centre products separately from the standard phone seats, so price the exact product you need. You get unlimited US and Canada calling, texting, video meetings and an auto attendant. The one number to watch is call reliability (7.5), which trails Nextiva and RingCentral in our rubric. Teams that live in call notes and want less manual admin get the most here; if raw uptime is your first priority, weigh that score. For most modern teams, the AI time-savings are the reason to choose it.
4. Quo (formerly OpenPhone) – Best for startups and lean teams
Quo – the product formerly called OpenPhone – is the startup favourite, and it tops our value (9.0) and ease-of-setup (9.0) scores. You can have shared numbers, a team inbox and texting running in an afternoon with no IT help. Verified pricing is about $19 per user per month on annual billing at the entry tier, rising to roughly $33 and $47 for the higher plans; a three-person startup lands near $685 a year. Texting is a genuine strength – shared SMS inboxes, snippets and automations – and integrations cover Zapier, HubSpot and Slack. The honest gap is that there is no native video meeting and the feature depth is lighter than the enterprise tools, so a support desk or a 50-seat company will outgrow it. For a small, fast-moving team that wants shared numbers and great texting without a contract, it is the easiest yes on the list.
5. Zoom Phone – Best for teams already on Zoom
If your team already meets in Zoom, Zoom Phone is the obvious add: it lives inside the same Zoom Workplace app, so calling, meetings and chat share one interface and one login. It scores well on reliability (8.5) and setup (8.5). Pricing starts near $10 per user per month on a metered plan, with an unlimited US and Canada plan a tier up, so price the calling volume you actually have. You get texting, a native video tie-in, an auto attendant and Zoom’s AI Companion for summaries. The value score (7.0) reflects that the cheap metered tier can cost more than it looks once per-minute calling and add-ons are counted, and that international is extra. For a Zoom-centric company that wants one vendor for meetings and phone, it is a clean, familiar choice; standalone phone buyers have cheaper unlimited options.
6. Aircall – Best for sales and support desks on a CRM
Aircall is built for sales and support teams that live inside a CRM or helpdesk, and it scores top-tier on integrations (9.0): Salesforce, HubSpot, Zendesk and Intercom ties are first-class, with click-to-dial, call logging and power-dialling. Pricing starts around $30 per user per month on annual billing with a three-seat minimum, so it is priced for teams, not solo operators – which is why its value score (6.5) is the lowest of the mainstream picks. You get unlimited US and Canada calling, an IVR and call routing, and analytics built for a queue. Texting is US and Canada only and there is no native video. The drawback is simply cost: you pay for the call-centre tooling whether or not you use all of it. For a revenue team that measures every call and wants it in the CRM, the integrations justify it; smaller generalist teams will find better value elsewhere.
7. JustCall – Best for CRM-driven sales and SMS outreach
JustCall is the other strong CRM-calling option, and it pairs high integration (9.0) and feature (8.5) scores with a real SMS strength – bulk texting, campaigns and automations that outbound sales teams lean on. AI call scoring and agent assist are built in. Pricing starts around $29 per user per month, usually on annual billing, so like Aircall it is priced for a team rather than a single operator. You get unlimited US and Canada calling, an IVR, and deep ties into Salesforce, HubSpot, Pipedrive and the common helpdesks. There is no native video and support scores a middling 7.0. The honest read: JustCall competes directly with Aircall, often a little cheaper, with stronger texting and slightly lighter polish. If your team sends as much SMS as it makes calls and wants it all logged in the CRM, it is a sharp value.
8. 8×8 – Best for unlimited international calling
8×8 is the pick when international calling is the whole point: its plans include unlimited calling to dozens of countries, which almost no one else matches at a flat per-seat rate. It scores well on reliability (8.5) and carries a built-in contact centre for teams that need queues and supervisors. The catch in 2026 is pricing transparency: 8×8 has moved to a quote-based model, with ‘Request a quote’ on every package instead of a published per-seat price, so you cannot self-serve a number and must talk to sales. You get texting, video, an auto attendant and strong analytics. Support scores the lowest here (6.5), a recurring theme in user feedback. For a company that calls abroad every day and wants one bill for phone and contact centre, 8×8 is genuinely differentiated; teams that want a price on a page and light support needs should look at Nextiva or RingCentral first.
9. CloudTalk – Best for international call-centre numbers
CloudTalk is a call-centre-first platform whose standout is breadth of local numbers – 160-plus countries – so a small team can appear local in many markets at once. It scores strongest on integrations (8.5), with solid CRM and helpdesk ties, call routing and analytics built for a queue. Pricing starts around $25 per user per month on annual billing. You get an IVR, call recording and reporting; texting is limited and there is no native video meeting. The drawbacks are the missing video and a support score (7.0) that trails the leaders. CloudTalk sits close to Aircall and JustCall in intent – a sales or support desk that wants its calls in the CRM – but wins specifically when international local presence matters more than unified communications. If you need lots of country numbers and tight routing, it is a focused, fair-value choice.
10. GoTo Connect – Best value all-in-one UCaaS
GoTo Connect is the value all-rounder: one plan folds in phone, video meetings, texting and a genuinely easy visual dial-plan editor that lets a non-technical admin draw the call flow by dragging boxes. Pricing starts around $26 per user per month, and higher tiers add more international and contact-centre features; many countries are included in the calling plan. It scores evenly across the rubric with no weak spot, which is the point – you are not paying for a specialism you will not use. You get an auto attendant, unlimited US and Canada calling and a broad set of integrations. The honest knock is that the interface feels a step behind the newest tools and there is no standout feature to rave about. For a small or mid-size business that wants phone and meetings in one affordable package and easy admin, GoTo Connect is an easy shortlist pick.
11. Ringover – Best for unlimited calling to Europe and beyond
Ringover is a European-built cloud phone system whose hook is unlimited calling to around 110 countries on a single per-seat price – strong value (8.0) for any team that calls abroad without wanting 8×8’s quote process. Pricing starts near $15 per user per month. You get texting, video, an auto attendant and the common CRM integrations, with a clean, modern app. It scores solidly and evenly, with support (8.0) notably better than several larger rivals. The trade-off is a smaller US footprint and brand presence than RingCentral or Nextiva, so North-America-only buyers may not need what makes it special. For a team with real international calling – sales into Europe, distributed staff, suppliers abroad – Ringover delivers genuinely unlimited global minutes at a fair price, which is a rarer combination than the category makes it sound.
12. Microsoft Teams Phone – Best for Microsoft 365 organisations
If your company already runs Microsoft 365, Teams Phone turns Teams into your phone system without a second app, and its integration score (9.0) and call reliability (8.5) are both near the top. Teams Phone licensing starts around $10 per user per month on top of your M365 subscription, but to make and take external calls you also need a Microsoft Calling Plan, Operator Connect or direct routing – which is where the value score (6.5) and the setup-and-admin score (6.0, the lowest here) come from. You get video (Teams), an auto attendant and an enterprise directory. Texting is limited compared with the SMS-first tools. The honest read: for an all-Microsoft shop this is the most natural choice and the calls are rock-solid, but the calling-plan layer makes the true cost and the setup harder than any self-serve tool here. Price the calling plan, not just the Teams Phone add-on.
13. Google Voice – Best value for Google Workspace teams
Google Voice is the simplest, cheapest option for a team that already pays for Google Workspace. It scores top of the field on ease of setup (9.0): assign a number from the admin console and a user is live in minutes, inside Gmail and the Voice app. Pricing is tiered at about $10, $20 and $30 per user per month, and requires a Workspace subscription. You get US texting, voicemail transcription, and video through Google Meet; ring groups and an auto attendant appear on the higher tiers. The feature score (6.5) is the honest limiter – there is no deep call-centre tooling, texting is US-only, and international is metered. For a small Workspace team that mostly needs a reliable business number, voicemail and simple routing, the value is hard to beat; teams that need SMS campaigns, CRM calling or a real IVR should choose a dedicated system.
14. Vonage – Best for configurable, add-on-driven setups
Vonage is a mature unified-communications platform (now part of Ericsson) built around a large app marketplace and an a-la-carte model. Entry pricing advertises from about $13.99 per line per month, but that headline is deceptive: many capabilities – call recording, more texting, CRM connectors – are paid add-ons, so the real monthly cost climbs once you build the setup you need. That add-on model is also the strength: you can configure precisely what you want. It scores evenly with good support (8.0) and reliability (8.0). You get video, an auto attendant and unlimited US and Canada calling; international and several features are extra. The drawback is pricing clarity – budget for the add-ons, not the teaser line. For a business that wants to assemble a tailored system from a proven platform and does not mind pricing it line by line, Vonage is a credible, configurable choice.
15. Ooma – Best budget pick with no contract
Ooma Office is the budget small-business pick: no contracts, easy DIY setup (8.5) and a virtual receptionist included even on the entry plan. Pricing advertises from about $19.95 per user per month, which keeps a small office’s bill low and predictable. You get unlimited US and Canada calling, a mobile app and a virtual receptionist to route callers; texting, video meetings and desktop features appear on the Pro and Pro Plus tiers. It scores well on value (8.0) and setup but lower on integrations (6.5) – there is no deep CRM ecosystem here. The honest framing: Ooma is closer to a dependable small-business utility than a modern collaboration suite, and that is exactly why budget-conscious owners like it. For a shop, clinic or small office that wants a reliable number, an auto attendant and no contract at the lowest sensible price, Ooma is the value answer; integration-heavy teams should look up the list.
16. Grasshopper – Best for solo operators and a single business line
Grasshopper is not a full phone system and does not try to be – it is a virtual business number that rings on the phone you already own, which is exactly right for a solo operator or a side business. Pricing is flat, from about $14 per month, not per user, so one price covers a solo with a couple of extensions – a different and often cheaper model than the per-seat tools above. You get texting, a basic auto attendant, voicemail and call forwarding. It tops the list on ease of setup (9.0) because there is almost nothing to configure. The limits are the point of the score (7.0): no video, no real integrations, no call-centre tooling, and it runs over your existing carrier rather than replacing it. For a freelancer, consultant or one-person shop that just wants to keep business calls off a personal number without paying per seat, Grasshopper is the simplest answer on the page.
Which business phone system fits your situation?
The right pick depends less on features than on how your team communicates, how many seats you need, and whether you call internationally. This matrix maps the common situations to the provider that fits, with the deeper guide for each.
| Your situation | Start with | Why |
|---|---|---|
| Solo operator or freelancer | Grasshopper, Google Voice | A flat or cheap single line on the phone you already own; no per-seat cost. |
| Small office (2-20) | Nextiva, GoTo Connect | All-round voice, video and messaging with easy admin and strong support. |
| Startup or lean team | Quo (OpenPhone) | Shared numbers and great texting, live in an afternoon, no contract. |
| Outbound sales team | JustCall, Aircall | CRM-native calling, power dialling, SMS campaigns and call scoring. |
| Support desk / call centre | Aircall, CloudTalk, 8×8 | Queues, IVR, routing and analytics built for inbound volume. |
| Remote or distributed team | Dialpad, RingCentral | Mobile-first apps, AI notes and reliable calling across locations. |
| Law or accounting firm | See our VoIP for law firms guide | Call logging, confidentiality and per-matter routing matter most – read the guide. |
| Already on Zoom / Microsoft 365 / Google Workspace | Zoom Phone / Teams Phone / Google Voice | Add phone inside the suite you already pay for and already know. |
| Lots of international calling | 8×8, Ringover | Unlimited or very broad country calling on a flat per-seat price. |
| Just need calls answered, not a phone system | AI receptionist services | A done-for-you answering layer – compare AI receptionists. |
| Want to build your own voice agent | AI voice agent platforms | A developer platform, not a phone system – see AI voice agents. |
VoIP vs cloud phone system vs PBX vs landline
The terms overlap, which is why shoppers search for all of them. VoIP phone system, cloud phone system, VoIP service and business phone system now describe the same thing in practice: software that carries your calls over the internet and gives you a business number, voicemail, routing and apps. A traditional PBX is the older model, a box in a closet that you buy, power and maintain, and a landline is the copper phone line it sat on. The industry has moved to hosted VoIP because there is no hardware to own, it scales by adding a user in software, and it costs a fraction of a maintained PBX. If you see “cloud PBX” or “hosted PBX,” that is simply a VoIP service with PBX-style features, delivered from the provider’s data centre rather than your closet.
Do you need desk phones for a VoIP service?
Because the system is software, your team can make and take business calls from the apps on devices they already own, with no new handset and no wiring. If you do want physical phones, buy IP (SIP) desk phones your provider supports, or reuse compatible models; avoid old analogue handsets, which need an adapter. A common setup is apps for most staff plus a handful of desk phones at shared desks or a front desk.
Can you keep your number?
Number portability is a regulated right, so you are not locked to your current carrier. Start the port after you have signed up with the new provider, give them a recent bill to match the account details, and do not cancel the old line until the transfer finishes. If you want a business line on your personal phone, every system here runs a mobile app that keeps work calls and texts separate from your personal number.
How we evaluated business phone systems

How to choose a business phone system
Start with how your team actually communicates. If you mostly make and take calls, prioritise call quality, reliability and the mobile apps. If you run outbound sales or a support desk, weight CRM and helpdesk integrations and call routing. Teams that want to cut admin time should look hard at AI features – transcription, summaries and an AI receptionist can replace a lot of manual work. Then check the real per-user cost at the tier you need, whether unlimited calling, texting and international minutes are included, and how painful it is to port your existing numbers. Finally, match the shortlist to your situation using the matrix above, and read the individual reviews before you commit.
