1. RingCentral RingEX: Best overall
PCMag score: 4.5/5. RingEX is the broadest choice in this group for companies that expect their phone system to grow with them. It combines business calling with team messaging, meetings, integrations, call recording, analytics, and AI features such as call transcriptions and summaries.
RingEX supports browser, Windows, macOS, Android, and iOS clients. It also supports many Cisco, Poly, and Yealink desk phones, although you should verify the exact model and provisioning process before buying hardware. PCMag reported no dropped calls or distortion during testing.
#1 Best Overall
- Supports 4 (GRP2613) or 6 (GRP2613W) SIP accounts and 6 multipurpose line keys
- Power supply : Integrated Power over Ethernet (PoE) IEEE 802.3af Class 2 or Universal power adapter Input: 100-240V; Output: +5VDC, 0.5A. It does not use batteries.
- Swappable face plates to allow for easy logo customization. Equipped with noise shield technology to minimize background noise
- HD audio with support for all major codecs, including wideband codecs G.722 and Opus. Up to 24 digital BLF keys
- Integrated dual-band (2.4GHz and 5GHz) Wi-Fi 6 (802.11a/b/g/n/ac/ax) and Bluetooth (GRP2613W only)
RingCentral’s current pricing page displays annual Essentials pricing at $19.99 per user per month. Treat the figure as a starting point rather than a complete quote: the final plan, number of users, calling locations, taxes, and optional features can change the total.
Best fit: A company that wants integrations and room to add users, departments, and more advanced call management later.
Watch out for: Businesses comparing only the headline price may overlook plan differences and paid features. Confirm which AI, CRM, recording, and international-calling functions are included.
2. Intermedia Unite: Easiest for small businesses
PCMag score: 4.0/5. Intermedia Unite is more than a voice-only service. Its current Unite Pro plan includes more than 100 calling features, business texting, 50GB of storage per user, AI Assistant, AI Call Recap, CRM integrations, and meetings for up to 100 participants.
Quick wins for a faster PC:
Scan for outdated or missing drivers - takes under a minuteDriver Scan →Repair Windows errors before they cause bigger problemsFix Now →Fix the driver behind crashes, sound loss and screen glitchesFind Drivers →Official pricing lists Unite Pro at $27.99 per user per month and Unite Enterprise at $32.99. Pro also includes unlimited AI-enabled meetings and unlimited domestic and international calling to 34 countries, subject to the plan’s terms.
The relatively higher entry price can make sense when it replaces several separate subscriptions or when a small business lacks dedicated IT staff. Microsoft Teams users may also find the integrations useful.
Best fit: Startups and small businesses that value an approachable interface and a broad bundle more than the lowest per-seat price.
Watch out for: Compare the bundle with what you already pay for meetings, storage, messaging, and business texting. You may be paying for overlapping tools.

3. Zoom Phone: Best value for Zoom users
PCMag score: 4.0/5. Zoom Phone is a strong option when your staff already uses Zoom Meetings. The recommended comparison plan is US and Canada Regional Unlimited at about $15 per user per month. Zoom also offers a lower metered tier at about $10, but that plan charges for usage and is not automatically cheaper for people who make regular outbound calls.
Zoom Phone’s price needs careful interpretation. Confirm the country, annual or monthly billing term, and whether Zoom Phone is being purchased alone or as part of Zoom Workplace. A bundle can change both the price and the included features.
Rank #2
- Yealink Optima HD voice technology
- Opus codec support, Dual USB ports, Dual-port Gigabit Ethernet & Dual firmware images
- The full keyboard and intelligent search support simplifies user input
- Support for multi-touch operations, offering unbelievable ease of use
Zoom supports end-to-end encryption in restricted circumstances. During an active Zoom Phone call, select More → End-to-end encryption; on mobile, tap More → End-to-end encryption. Both parties must be in the same Zoom account, both must have the feature enabled, and automatic recording must be disabled or stopped.
That security mode is not available for ordinary external telephone numbers and can prevent transfer, monitoring, merge, hold music, park, call flip, and other controls. It also may not work from the web client or many certified desk phones.
Recommended Free Tools
Best fit: Teams already invested in Zoom that want predictable domestic calling without paying for a larger UCaaS bundle.
Watch out for: The $10 metered plan can be misleading if employees make frequent calls. Also check that your desk-phone model remains certified; providers periodically stop supporting older hardware.
4. Vonage Business Communications: Best as a communications hub
PCMag score: 4.0/5. Vonage can bring calling, team messaging, video meetings, faxing, integrations, and call handling into one platform. Its Mobile plan is listed at $13.99 per user per month when billed annually.
The inexpensive entry plan does not necessarily include every function a business expects. Desk-phone support, integrations, video conferencing, and other capabilities are distributed among higher plans or add-ons. Price the exact configuration for your business rather than assuming the base plan is a full replacement for your current tools.
Free tools Windows power users keep installed
One-click scans. No signup required.
Best fit: Businesses that want to assemble a unified communications system around a phone service.
Watch out for: Add-ons can erase the apparent savings. List every required function before comparing Vonage with an all-in-one competitor.
5. 8×8 Work: Best for basic calling
PCMag score: 4.0/5. 8×8 Work is worth considering if you want standard business calling and do not need every advanced collaboration or AI feature. The listed pricing is $15 per user per month for X1, $25 for X2, with X4 positioned as the advanced tier.
X4 is the listed tier with call barging, monitoring, and whispering. Some integrations and advanced AI functions cost extra, and PCMag described automatic call transcription as being in beta during testing. Do not assume that X1 includes the platform’s full AI feature set; some advanced sentiment-analysis features also cost extra.
Rank #3
- Supports 4 SIP accounts and 4 multi-purpose line keys
- Swappable faceplate to allow for easy logo customization
- GRP2612W includes built-in dual-band Wi-Fi support. Ethernet cord must be disconnected to enable Wi-Fi capability
- HD audio supporting all major codecs, including wideband codecs G.722 and Opus Up to 16 digital BLF Keys
- Enterprise-level protection including secure boot, dual firmware images, and encrypted data storage
“Unlimited” calling also needs scrutiny. Calling zones, fair-use limits, international destinations, mobile numbers, and premium numbers can differ by plan.
Best fit: A company that wants conventional business phone features and can identify exactly which higher-tier tools it needs.
Watch out for: Comparing X1’s price with a competitor’s fully featured plan produces an unfair comparison.
6. Dialpad Connect: Best AI-focused option for small teams
PCMag score: 3.5/5. Dialpad is particularly appealing to teams that want AI assistance around calls. Its current pricing lists Standard at $15 per user per month and Pro at $25, with higher monthly pricing possible when you do not commit annually.
Dialpad can provide transcription and call intelligence, but plan and seat restrictions matter. The tested review identified Standard as supporting one person and Pro as supporting up to 10 users; verify those limits in the purchase flow because providers can change plan rules separately from headline prices. Some advanced analytics are reserved for Dialpad’s contact-center product.
Best fit: A small team that will actively use AI notes, transcription, and call workflows.
Watch out for: A low per-user price is less useful if your team exceeds the plan’s seat limit or needs contact-center analytics.
7. Microsoft Teams Phone: Best for Microsoft 365 users
PCMag score: 3.5/5. Teams Phone is most logical when your organization already lives in Microsoft Teams and Microsoft 365. Microsoft currently lists three materially different options: Teams Phone Standard at $10 per user per month paid yearly, Teams Phone with pay-as-you-go calling at $13, and Teams Phone with Calling Plan at $17.
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Clear out junk files and repair common Windows errors3Fix the driver behind crashes, sound loss and screen glitchesThe $10 Standard license is not a complete standalone business phone service. It requires a separate Teams license, and it does not provide the same PSTN calling package as the $17 Calling Plan option. Add the existing Microsoft license cost and any calling charges before comparing it with RingCentral or Zoom.
Teams supports end-to-end encryption for supported one-to-one Teams calls; it is not a general guarantee for PSTN calls. Administrators configure it in the Teams admin center by going to Enhanced encryption policies, selecting the default policy or choosing Add, setting End-to-end call encryption to Not enabled, but users can enable, and selecting Save. Users must then enable encrypted calling in their own Teams settings.
Rank #4
- Quick and easy installation: Connect the main console to analog lines via RJ11; cordless handsets/desksets pair wirelessly with one-touch DECT 6.0 technology—no professional wiring or assistance needed for fast small office setup.
- Expandable to 10 stations: Grow your 4-line small business phone system seamlessly by adding up to 9 cordless handsets or desksets—ideal for scaling operations without replacing equipment.
- Professional auto attendant per line: Automatically answers calls on each of the 4 lines, offers company directory access, routes to extensions, and records voicemail for efficient, polished call management.
- Reliable digital answering system: Captures up to 180 shared minutes of incoming messages, announcements, and memos—ensuring no important calls are missed during busy hours.
- Enhanced productivity features: Full-duplex speakerphone for natural conversations, extra-large display, caller ID/call waiting, 100-name phonebook, 32 speed dials, cordless headset support, intercom, and customizable music-on-hold via 2.5mm jack.
Teams E2EE disables live captions, transcription, transfer, merge, park, recording, apps, and adding participants. Compliance recording also disables E2EE.
Best fit: Organizations that already pay for Microsoft 365 and want desk-phone or Teams-based calling.
Watch out for: License stacking. The advertised phone price may be only one line item in the Microsoft bill.
8. Ooma Office: Best guided entry point
PCMag score: 3.5/5. Ooma Office is designed for small businesses and VoIP newcomers that want a guided setup. Current monthly pricing is $19.95 for Essentials, $24.95 for Pro, and $29.95 for Pro Plus.
Pro adds videoconferencing, call recording, enhanced call blocking, and voicemail transcription. Pro Plus adds hotdesking, call queues, and CRM integration. Ooma says there is no contract and that customers can cancel at any time. The tested version does not include AI features.
The advertised subscription is not necessarily the complete bill. Taxes and regulatory fees vary by location, while additional numbers and toll-free service may cost extra.

PCMag score: 3.5/5. Zoho Voice is attractive when your business already uses Zoho applications or needs a modest calling setup. Paid plans begin at about $10 per user per month billed annually. Zoho also identifies a free tier with 250 outgoing minutes for one user, but availability and minute rules can vary by region.
Zoho Voice can transcribe voicemails, but it does not provide live call transcription or AI-generated call summaries in the tested review. It also lacks built-in video conferencing.
Best Value
- Make more natural and life-like calls with Polycom HD Voice
- 2. 8” color display: an engaging experience offering visual information at a glance
- Two Gigabit Ethernet ports offer cost savings and performance benefits
- USB port enables users to move data around more quickly
- Integrates with more than 60 industry leading call control platforms
Best fit: A very small business with light calling needs and an existing Zoho ecosystem.
Watch out for: Regional eligibility and minute allowances. Verify both before treating the free or low-cost plan as a long-term solution.
How to calculate the real VoIP cost
Start with the monthly seat price, then build a simple total-cost estimate:
- Count required users. Include receptionists, managers, remote workers, shared phones, and temporary staff who need individual licenses.
- Separate calling types. Identify domestic, international, toll-free, premium, and mobile-number usage. “Unlimited” usually applies only to defined destinations.
- Add required software licenses. Teams Phone Standard, for example, requires a separate Teams license. A phone plan may also overlap with Zoom, CRM, storage, or contact-center subscriptions.
- Price hardware. Include desk phones, headsets, adapters, shipping, replacement units, and installation. A browser-only deployment may avoid much of this cost.
- Include taxes and fees. These can be especially important for services such as Ooma, where location affects the final bill.
- Budget for administration and connectivity. Cloud management reduces PBX hardware, but poor Wi-Fi, packet loss, latency, or inadequate bandwidth can require network upgrades.
For example, 10 users at $15 per month appears to cost $150 monthly before taxes and extras. If five users need a $10 monthly add-on, the software total becomes $200. Add a separate Microsoft or Zoom license, phone hardware, and regulatory fees before deciding that the cheaper headline plan wins.
What to test before switching
- Run calls from every important location. Test the office, home networks, VPN connections, and mobile apps. Remote workers’ Wi-Fi quality is often the weakest link.
- Test the actual call paths. Call external numbers, transfer calls, park calls, use auto attendants, retrieve voicemail, and test business texting if it matters.
- Check emergency calling details. Confirm how the provider handles registered locations, remote users, and emergency-service updates.
- Verify desk-phone models. Support for Poly, Cisco, or Yealink does not guarantee support for every model. Ask whether the provider provisions the device automatically.
- Check recording and encryption conflicts. Zoom and Teams restrict E2EE when recording or certain call controls are required. A security feature that disables your compliance workflow may not be usable in practice.
- Review cancellation terms. Compare annual commitments, number-porting fees, hardware return rules, early termination charges, and price changes at renewal.
Where Grasshopper fits
Grasshopper can be useful for a sole proprietor or very small business that mainly needs a professional number and call routing. It generally routes calls through existing mobile or landline devices, with optional VoIP or Wi-Fi calling. It is not a full UCaaS replacement: the service lacks external SIP support and broad business-service integrations. Choose it for a simple business number, not for a contact center, unified collaboration suite, or sophisticated call-management platform.
FAQ
What is the best business VoIP service in 2026?
RingCentral RingEX is the strongest general-purpose choice in this comparison, with a PCMag score of 4.5/5 and broad integrations, scalability, and AI call features. Intermedia Unite and Zoom Phone are better fits for specific needs such as easy administration or low-cost calling for existing Zoom users.
Is business VoIP cheaper than a traditional phone system?
It can be, because cloud VoIP reduces PBX hardware and on-site maintenance. The actual savings depend on user count, calling destinations, required software licenses, hardware, taxes, add-ons, and internet upgrades. Compare the complete monthly and one-time cost rather than the advertised seat price.
Does business VoIP require fast internet?
It requires a stable connection with sufficient bandwidth and low packet loss and latency. Unstable Wi-Fi, congested networks, and poor home-office connections can cause dropped calls, garbled speech, or failed connections even when the VoIP provider itself is working normally.
Quick wins for a faster PC:
Scan for outdated or missing drivers - takes under a minuteDriver Scan →Repair Windows errors before they cause bigger problemsFix Now →Is VoIP end-to-end encrypted?
Not automatically in every call. Zoom and Microsoft Teams support end-to-end encryption under specific conditions, and enabling it can disable recording, transcription, transfers, or other call controls. Treat E2EE as a feature to configure and test, not as a universal property of every VoIP call.
Should a small business choose a metered VoIP plan?
Only after estimating actual outbound minutes and destinations. A metered plan can be economical for occasional callers, but a regional unlimited plan may cost less for employees who make regular domestic calls. Check whether mobile, international, premium, and toll-free numbers are included.
The Bottom Line
Bottom line: RingCentral RingEX is the best all-around business VoIP service in this 2026 roundup. Intermedia Unite is worth the premium when easy administration and bundled collaboration tools matter, while Zoom Phone is a compelling value for businesses already using Zoom and needing predictable US and Canada calling. Microsoft Teams Phone can be inexpensive only after you include the required Microsoft licenses. Whatever you choose, test the service on real office and home networks, verify desk-phone compatibility, and calculate taxes, add-ons, and calling limits before signing an annual contract.
