10 Best VoIP Providers to Move Your Business Phone to the Cloud in 2026
Moving a business phone system off a physical PBX and onto a cloud VoIP platform tends to solve three problems at once: it cuts hardware costs, it lets employees take calls from anywhere with an internet connection, and it usually bundles in messaging and video that would otherwise require separate subscriptions. The market for business VoIP has consolidated a fair amount in recent years through acquisitions, so a few names on this list now sit under different corporate umbrellas than they did when they first built their reputation. Here are ten providers worth evaluating, along with what changed in their ownership or branding that older buying guides sometimes miss.
1. RingCentral
RingCentral remains one of the largest independent UCaaS providers, offering voice, video meetings, team messaging, and fax under one platform. It integrates with Microsoft 365, Google Workspace, and Salesforce, which makes it a common choice for mid-size and larger businesses that already run their operations through one of those ecosystems.
Strengths: a genuinely deep feature set, strong call quality on paper, and a large partner and integration network. Tradeoffs: the platform has enough settings and admin options that very small teams sometimes find it more than they need, and the cost climbs quickly once you move past the entry tier. RingCentral publishes tiered per-user monthly pricing on its own site, and because SaaS pricing changes several times a year, checking the current rate card directly before budgeting is worth the extra step rather than relying on a number quoted in an older article.
2. Nextiva
Nextiva positions itself around unified communications with a strong customer support reputation, offering voice, video, and chat in a single dashboard alongside CRM-adjacent tools like customer surveys and a shared inbox for support tickets. It is a common recommendation for businesses that want phone service and light customer relationship tools without buying two separate platforms.
The entry-level plan trims out some of the automation and analytics features found higher up the tier list, and the more advanced plans require either a larger seat count or a custom quote. As with the rest of this list, Nextiva’s published pricing shifts periodically, so treat any specific dollar figure as a starting point for a conversation with sales rather than a locked-in rate.
3. Vonage
Vonage built its early reputation on consumer VoIP before pivoting hard into business communications, and it has been owned by the Swedish telecom equipment maker Ericsson since 2022, following a roughly 6.2 billion dollar acquisition. The Vonage brand and product line continued operating largely as-is under Ericsson, with the acquisition aimed more at Vonage’s API and communications platform business than at replacing the consumer-facing brand.
Vonage Business Communications covers call forwarding, voicemail-to-email, and video conferencing, and it plugs into common CRMs. Smaller teams sometimes find the add-on fees for extra features add up faster than expected, so it is worth mapping out which features you actually need before comparing the advertised entry price against a competitor’s.
4. 8×8
8×8 offers an all-in-one platform spanning voice, video, team chat, and contact center software, aimed at businesses that want a single vendor handling both internal communications and customer-facing support queues. Its compliance certifications and security features make it a frequent shortlist candidate for regulated industries like healthcare and finance.
The tradeoff for that breadth is a steeper setup process than a phone-only provider, and the more advanced contact center tiers are priced well above the basic voice plans. Businesses that only need a phone system without a contact center attached may find some of 8×8’s feature set going unused relative to its cost.
5. Grasshopper
Grasshopper targets solo entrepreneurs and very small businesses that mainly need a professional phone number, extensions, and voicemail rather than a full unified communications suite. It is now part of the GoTo family of products (the company formerly known as Citrix’s GoTo division and LogMeIn), which acquired Grasshopper as part of a broader consolidation of small-business communication tools.
Because Grasshopper is deliberately scaled down, it does not include video conferencing or a desk-phone hardware option, running instead through a mobile and desktop app tied to a virtual number. For a freelancer who wants to separate a business line from a personal cell number without buying a second phone, that simplicity is the whole appeal.
6. Ooma
Ooma runs both a residential VoIP product and a business line called Ooma Office, which has reorganized its plan names over the past couple of years into Essentials, Pro, and Pro Plus tiers. The Pro and Pro Plus levels add features like call recording, video conferencing, and desktop app integrations that the entry Essentials plan leaves out.
Ooma tends to compete on straightforward pricing and minimal contract commitments rather than an expansive feature list, which appeals to small businesses that want predictable monthly costs more than they want a deep integration ecosystem. Current plan pricing is best pulled from Ooma’s own comparison page, since tier names and pricing have shifted since the product first launched.
7. Dialpad
Dialpad differentiates itself with AI-driven features built directly into calls: live transcription, automatic call summaries, and sentiment cues during customer service calls. It runs entirely in the browser or through desktop and mobile apps, with no on-premises hardware required, and integrates with Google Workspace particularly closely.
The AI transcription and coaching tools are the main reason teams choose Dialpad over a more traditional VoIP provider, especially sales and support teams that want searchable call records without a separate call-recording tool. Smaller teams that do not need the AI layer may find a simpler, cheaper provider covers their needs just as well.
8. Mitel
Mitel has decades of history in enterprise telephony, going back to on-premises PBX hardware before expanding into cloud UCaaS with MiCloud Connect. It remains active and continues to market itself as a leading global UC provider, with a large partner and reseller network handling most sales rather than a self-serve online checkout.
That partner-driven sales model means Mitel is less of a fit for a small business that wants to sign up online in twenty minutes, and more of a fit for a mid-size or enterprise organization willing to go through a sales consultation to get a quote tailored to their existing phone infrastructure and headcount.
9. Zoom Phone
Zoom Phone extends the same company’s video conferencing platform into a full cloud phone system, which makes it a natural add-on for any business already using Zoom Meetings for video calls. Calls, meetings, and team chat all live inside the same Zoom app, so employees are not switching between multiple pieces of software for different communication types.
Its per-user pricing tends to undercut some of the more established enterprise UCaaS players, partly because Zoom can spread infrastructure costs across its much larger video conferencing user base. The tradeoff is that some of the deeper call center and compliance features found in dedicated UCaaS platforms are less mature in Zoom Phone, though the company has been closing that gap steadily.
10. GoTo Connect
GoTo Connect is the current name for the cloud phone platform that started life as Jive Communications before LogMeIn acquired Jive in 2018 and later rebranded its entire company, including this product line, from LogMeIn to GoTo in 2022. Buying guides that still list “Jive by LogMeIn” as a standalone brand are working from outdated naming, since both the parent company and the product itself now go by GoTo.
GoTo Connect bundles phone, meetings, and messaging with a visual call flow editor that lets non-technical admins build out auto attendants and call routing without submitting a support ticket. It sits alongside GoTo Meeting and GoTo Resolve, formerly LogMeIn Rescue, under the same corporate umbrella, which can simplify billing for a business that already uses other GoTo products.
Security and Compliance Considerations
Cloud phone systems carry call recordings, voicemail transcripts, and sometimes customer payment information across the internet, which puts them squarely inside the same compliance conversations as any other cloud software vendor storing sensitive data outside a company’s own servers. Healthcare practices need a provider willing to sign a business associate agreement under HIPAA before any patient information touches the platform, and financial services firms typically need call recording retention policies that satisfy their specific regulator, whether that is FINRA, the SEC, or a state-level requirement.
Not every VoIP provider on this list supports every compliance framework out of the box, and some gate HIPAA or PCI compliance behind higher pricing tiers rather than including it by default. Asking a sales representative directly whether a specific compliance requirement is met on the plan you are actually buying, rather than assuming it is included because the company mentions compliance somewhere on its marketing site, avoids an unpleasant surprise during an audit.
Encryption in transit is close to universal among the providers above, but encryption at rest for stored voicemails and call recordings varies more than most buyers expect. If your business handles sensitive customer conversations, it is worth asking specifically how recordings are stored, who can access them internally at the vendor, and how long they are retained before deletion.
Porting an Existing Business Number
Keeping an existing phone number when switching providers, rather than starting over with a new one, is almost always possible but rarely instant. Porting a number away from a traditional carrier and into a VoIP platform typically takes anywhere from a few days to a few weeks depending on the losing carrier’s responsiveness, and businesses should plan to run both systems in parallel during that window rather than assuming a same-day cutover.
A common mistake is canceling old phone service before the port has fully completed, which can strand the number in limbo between carriers. The safer sequence is to initiate the port request with the new provider, wait for confirmation that the number has fully transferred and is receiving calls correctly, and only then cancel the old service. Most of the providers listed here have a dedicated porting team or a porting FAQ page that walks through the specific paperwork required, since it usually involves a copy of a recent bill and a signed letter of authorization.
Mobile and Remote Work Support
Every provider on this list offers a mobile app that turns a smartphone into an extension of the business phone system, letting remote or field employees make and receive calls from their business number without giving out a personal cell number. Quality and feature parity between the desktop and mobile apps varies more than the marketing pages suggest, though; some providers treat the mobile app as a full-featured client, while others leave call transfer, conferencing, or voicemail management noticeably more limited on mobile than on desktop.
For businesses with a genuinely distributed or remote workforce, testing the mobile app specifically, rather than just the desktop or browser experience, during a trial period catches this gap before it becomes a daily annoyance for field staff. Wi-Fi calling quality on the mobile apps also depends on the same network conditions that affect desktop VoIP calls, so remote employees on unreliable home internet may need a mobile data fallback configured as a backup.
Trial Periods and How to Actually Use Them
Most of the providers above offer either a free trial or a money-back guarantee window, and the businesses that get real value out of that period are the ones who use it to simulate an actual workday rather than just poking around the settings menu. Setting up a real auto attendant, forwarding a handful of test calls between departments, and having two or three employees actually place calls from different locations surfaces problems that a five-minute demo call never will.
It is also the right window to test customer support responsiveness before committing, since a slow support response during a paid trial is a fair preview of what happens after a contract is signed and the provider has less incentive to move quickly. Sending a support ticket with a real, moderately technical question during the trial and timing the response is a small effort that tells you more than most sales calls do.
What Actually Changes When You Move to the Cloud
The most immediate change is where the intelligence in the phone system lives. A traditional PBX keeps call routing logic in a physical box in a server closet; a cloud VoIP platform keeps that logic in the provider’s data centers, which means adding a new employee or changing an auto attendant menu is a few clicks in a web dashboard instead of a truck roll from a phone technician. That shift alone is usually the biggest quality-of-life improvement businesses report after switching.
Call quality depends heavily on network conditions in a way traditional phone lines never had to worry about. A business with unreliable or congested internet service will notice choppy calls on any VoIP provider, regardless of how good that provider’s own infrastructure is, so a serious evaluation of office internet bandwidth and quality-of-service configuration on the router should happen before signing a contract, not after complaints start coming in.
Contract Terms Worth Reading Closely
Annual contracts usually come with a meaningfully lower per-user rate than month-to-month billing, but they also lock a business into a headcount commitment that can be awkward if the team shrinks. Growing teams benefit more from month-to-month or short-term commitments that let seat counts flex up without a renegotiation, while stable teams with predictable headcount can capture real savings by committing to an annual term.
Early termination fees, number porting timelines, and hardware ownership (whether desk phones are purchased outright or leased as part of the contract) are the details that cause the most friction after signing, not the headline monthly price. Getting a written answer on what happens if the business needs to cancel mid-contract, and how long porting an existing business number away from the provider would take if you switch again later, avoids a lot of the frustration that shows up in negative reviews for otherwise solid providers. It is a small ask during the sales process and a large one to sort out later without it in writing.
Matching a Provider to Business Size
Solo operators and very small teams are usually best served by Grasshopper or Ooma, since both are built around simplicity and predictable billing rather than deep integrations. Mid-size businesses that need CRM integrations, multiple departments, and reasonably sophisticated call routing tend to land on RingCentral, Nextiva, or Vonage. Teams already living inside Zoom for video get an easy on-ramp through Zoom Phone, and Google Workspace shops often gravitate to Dialpad for the tighter integration.
Larger organizations with existing telephony infrastructure, compliance requirements, or a need for a dedicated account team usually end up talking to Mitel, 8×8, or GoTo Connect, all three of which support the kind of custom deployment and negotiated contract that a self-serve small business plan is not built to handle. None of these providers is universally “the best,” despite what any single ranked list, including this one, might imply; the right choice depends on team size, existing software stack, and how much hand-holding a business wants during setup.
Questions Worth Asking Before Signing
A short list of direct questions during a sales call tends to surface more useful information than reading another comparison article. What happens to call quality during an internet outage, does the provider offer automatic failover to a mobile number or backup line? How many extensions and auto attendants are included at the plan tier being quoted, and what does the next tier up actually unlock? Is desk phone hardware included, available for purchase, or something the business has to source separately and configure itself?
It is also worth asking how the provider handles busy season or unexpected call volume spikes, particularly for businesses in retail, hospitality, or anything seasonal. A platform that performs fine at normal volume can behave differently once call queues get long, and a sales representative who can point to a specific customer reference in a similar industry is a stronger signal than a generic uptime percentage on a marketing page.
Finally, ask what the actual cancellation process looks like, not just what the contract says about it. Some providers make it simple to cancel with a support ticket, while others require a phone call during specific business hours or a formal written notice with a set number of days’ lead time. None of that shows up on a pricing page, but it matters considerably more than the sticker price once a business actually needs to make a change.
