How we researched these providers

The 8 best VoIP service providers for business, in detail

Each section starts with a short spec card, then what the official pages say, then the main trade-off. All prices are per user (or per line) per month in USD.

1. RingCentral RingEX

RingCentral RingEX is a cloud phone system with team messaging and video in one app. Core includes unlimited domestic calling in the US and Canada, multi-level auto attendant with up to 250 voice menus per account, shared lines, visual voicemail with transcription, basic call queues, on-demand recording, and video meetings for up to 300 participants.

Advanced ($25 annual, $35 monthly) adds CRM integrations (Salesforce, Zendesk, HubSpot and others), multi-site management, automatic call recording, unlimited internet fax, hot desking, call monitoring (whisper, barge), and 1,000 pooled toll-free minutes. RingCentral’s higher AI Customer Engagement bundles are quote-only.

RingCentral says it supports Enhanced 911 and lists a 99.999% uptime SLA. Its pricing page also notes extra charges such as a Federal Universal Service fee, an E911 service fee, and state and local taxes, plus required carrier (TCR) registration before you can send business texts.

2. Nextiva

Nextiva positions Core as “connect your team and customers”: inbound and outbound voice, business SMS, video meetings, screen and file sharing, call routing, team chat, and the mobile app. Its comparison table also covers features such as auto-attendant call menus and voicemail transcription; check which tier includes each one before you buy.

Engage adds customer-to-team texting, a toll-free number with up to 2,000 free 1-800 minutes, advanced reporting, and live chat. Scale ($75) moves into a full customer-experience platform with AI transcription, skills-based routing, and journey orchestration. Nextiva also sells an AI receptionist (XBert) as an add-on.

Read the fine print: Nextiva’s annual Small Business pricing is limited to new customers with 1 to 100 employees who sign a 12-month or longer agreement, and some features (such as single sign-on and CRM integrations) may carry extra setup or licensing fees.

3. Zoom Phone

Zoom Phone adds a cloud phone line to Zoom Workplace. The cheapest phone plan (US & CA Unlimited, added to Workplace Basic) includes unlimited domestic calling, domestic SMS and MMS, 50 pages of online fax a month, a domestic number, unlimited auto attendants, call queues with barge, monitor, and whisper, call recording, and post-call AI summaries.

The trade-off is the meeting side: with Workplace Basic, Zoom lists 40-minute meetings. The Pro Plus bundle ($20.50 annual) raises that to 30-hour meetings with 100 participants, and Business Plus ($24.50 annual) adds 300 participants, unlimited fax, and single sign-on.

Zoom lists nomadic E911 addressing for the US and Canada, number porting, toll-free numbers, desk phone provisioning, and bring-your-own-carrier support. Zoom’s plan table lists 24/7 live chat and phone support, but its support section limits live phone support to accounts with subscriptions over $200 a month.

4. Dialpad Connect

Dialpad Connect is Dialpad’s business phone plan for calls, messages, and meetings. Standard includes unlimited calls, HD calls and meetings, built-in messaging, real-time transcripts, and instant call summaries, which is unusual at this price.

Pro adds key CRM integrations, 24/7 support, and multi-office management. Enterprise adds single sign-on, user access controls, and unlimited office locations. Dialpad’s separate Sell and Support plans ($39 and $89 per user/month annual entry) are aimed at sales teams and contact centers.

Dialpad notes that the price you see may vary by region and currency, so confirm your quote. Its FAQ says Advanced plans on its Sell and Support lines can be month-to-month or annual, while Premium is annual only.

5. 8×8 X Series

8×8 sells its business phone and contact center service as X Series licenses. We couldn’t load a US price from 8×8’s pricing page on October 17, 2026 (the page returned a browser check to our tools), so we’re not quoting a number. Ask 8×8 for a quote.

What we could confirm comes from 8×8’s own help center: X2 licenses include unlimited calling to standard landline and mobile numbers within 14 countries, and X4 (and higher) licenses extend that to 48 countries, subject to fair use. Contact center licenses (X6–X8) use a pooled allowance of 4,000 minutes per user per month (8×8 help: calling countries for X Series).

That calling-zone design is the main reason to shortlist 8×8: if your team regularly calls customers in Europe, Asia, or Latin America, an X4 license may replace a separate international calling plan.

6. Google Voice (Google Workspace)

Google Voice is Google’s cloud phone service, added to a Google Workspace subscription. Starter ($10) is for up to 10 users and includes a number that rings on all your devices, unlimited domestic calling and US texting, voicemail transcription, three-way calling, call transfers, easy call recording, desk phone and ATA support, and 24/7 Voice support.

Standard ($20) removes the user cap and adds auto attendants and ring groups, call queuing, on-demand recording, eDiscovery for calls, voicemails, and texts, and SIP Link to connect existing carrier numbers. Premier ($30) adds unlimited international billing locations, automatic call recording, and advanced reporting with BigQuery.

Google says unlimited calling and texting apply in available markets, subject to the Voice Additional Terms of Service, and voicemails and texts can land in Gmail. Google also lists a single-user Voice Starter option in the US.

7. Microsoft Teams Phone

Microsoft Teams Phone turns Teams into a cloud PBX: make, receive, and transfer calls in the same app as chat and meetings. Teams Phone Standard ($10, paid yearly) is the phone system only; you add phone-network (PSTN) service through Microsoft’s Calling Plans, Operator Connect (a participating carrier), or Direct Routing (your own SBC).

Microsoft’s US bundles are Teams Phone with pay-as-you-go calling ($13), Teams Phone with Calling Plan ($17, 3,000 outbound domestic minutes in the US, UK, and Canada), and domestic plus international ($34, adding 600 international minutes). Microsoft says the calling-plan component is priced inclusive of US communication taxes and fees, including 911 fees, while the phone system part is taxed separately.

You need a Teams license as well: Microsoft notes some Microsoft 365 and Office 365 suites no longer include Teams. Microsoft lists a financially backed 99.999% uptime SLA and lets you port existing numbers to a Calling Plan.

8. Vonage Business Communications

Vonage Business Communications (VBC) sells three tiers priced per line. Mobile includes the desktop and mobile apps, unlimited domestic calling, SMS and MMS, and voicemail. Premium adds VoIP desk phone support, video meetings for up to 200 participants, team messaging, the VBC App Center (20+ integrations), and single sign-on. Advanced adds on-demand call recording (15 hours a month), visual voicemail with transcription, and call groups.

Pricing depends on how many lines you buy: the page shows $19.99, $17.99, and $14.99 per Mobile extension across its company-size brackets at standard rates. A 30% promotional discount applies to annual contracts bought online (the fine print gives both December 30 and December 31, 2026 as the end date). Monthly plans aren’t eligible for that discount.

Vonage says monthly contracts carry no early termination fee (but no refunds), while canceling an annual contract early can cost up to the total contract value. Taxes and fees are extra, and one local company number is included with online purchases.

Which business VoIP provider is best for you?

Use this as a shortlist, then confirm current pricing and terms with the vendor. These picks are based on official documentation and listed prices, not hands-on testing.

• Most small businesses wanting a full phone system: RingCentral RingEX Core ($20 annual).
• Lowest annual price with 24/7 support: Nextiva Core ($15 annual, new customers with 1–100 employees).
• Already using Google Workspace: Google Voice Starter (up to 10 users) or Standard if you need an auto attendant.
• Already using Microsoft 365 with Teams: Teams Phone with Calling Plan ($17 in the US) on top of your Teams license.
• Already using Zoom for meetings: Zoom Phone, ideally the Pro Plus or Business Plus bundle.
• Want AI call summaries without paying extra: Dialpad Connect Standard.
• Calling many countries: 8×8 X Series (ask for an X2 or X4 quote).
• Want month-to-month with no termination fee: Vonage (monthly plans).

How do you choose a business VoIP service?

Start with how your team works today, then compare total monthly cost, not just the headline price. These are the questions that change the answer most often:

1. Count users and devices. Decide who needs a direct number, who only needs an extension, and whether anyone needs a physical desk phone. Several providers rent or sell desk phones separately.
2. Match the software you already pay for. Google Voice needs Google Workspace for its business tiers; Teams Phone needs a Teams license; Zoom Phone plugs into Zoom Workplace. Native add-ons mean one admin console and one bill. Still choosing a suite? Our Google Docs vs Microsoft Word comparison is a good starting point.
3. Map your call flow. If callers should hear “press 1 for sales,” you need an auto attendant (IVR). If several people answer the same line, you need ring groups or call queues. Check which tier includes them: Google Voice puts auto attendants in Standard, for example.
4. Check texting rules. Business SMS in the US usually requires carrier registration before you can send messages; RingCentral, for example, notes that TCR registration is required and fees may apply.
5. Price the extras. Toll-free minutes, international calls, extra numbers, fax, recording storage, and taxes or regulatory fees can add up. Read the fine print under each pricing table.
6. Compare annual vs monthly. Annual billing is cheaper at every vendor that shows both, but it locks you in. Vonage, for example, charges early termination fees on annual contracts but not on monthly ones.
7. Plan for 911 and outages. Register each user’s physical address, decide how remote workers will update theirs, and keep a cell phone or backup power for outages (see the FCC section below).
8. Ask about number porting. Most providers, including Zoom and Microsoft, let you bring your existing business numbers. Schedule the port so calls don’t drop during the switch.

What is VoIP and how does it work?

VoIP (Voice over Internet Protocol) lets you make voice calls over a broadband internet connection instead of a traditional analog phone line. Per the FCC, a VoIP service converts your voice into a digital signal that travels over the internet; when you call a regular phone number, the signal is converted back into a regular telephone signal before it reaches the other person.

For a business, that means calls run through an app on a computer or phone (a “softphone”), a VoIP desk phone that plugs into your network, or a traditional phone connected to a VoIP adapter. The provider hosts the phone system in the cloud, so features that once needed an on-site PBX, like extensions, auto attendants, call queues, and voicemail-to-email, become settings in a web dashboard.

The FCC also lists the main trade-offs: you need an active broadband connection, some VoIP services don’t work during power outages, and 911 calls are handled differently than on a landline. If you’re still fuzzy on caller ID and what a “VoIP caller” is, our older explainer on what a VoIP caller is covers the basics.

	Business VoIP (cloud)	Traditional landline / on-site PBX
Where the system lives	Provider’s cloud; managed in a web portal	Phone company lines and equipment in your office
Devices	Softphone apps, VoIP desk phones, adapters	Desk phones wired to the PBX or phone line
Needs internet?	Yes, broadband required (FCC)	No (analog lines carry their own power)
Remote work	Same number on laptop and mobile app	Usually tied to the office
911 location	Registered address you must keep current (FCC)	Tied to the line’s fixed address

VoIP and 911 (E911): what does the FCC require?

The FCC requires providers of interconnected VoIP service (service that can call and receive calls from regular phone numbers) to provide Enhanced 911 as a standard, mandatory feature that customers can’t opt out of (FCC: VoIP and 911 Service). Providers must collect your physical location before activating service, give you easy ways to update it, send 911 calls with your callback number and registered location to the right emergency call center, and get your acknowledgement of any 911 limitations.

The FCC also warns that a VoIP 911 call may not reach the right call center or may not pass along your location if your registered address is out of date, and that VoIP may not work during a power outage or internet failure. Its tips: give your provider an accurate address, update it whenever you move, and consider backup power, a traditional line, or a cell phone as a fallback.

In practice, ask any provider on your shortlist how it handles dynamic location for remote and hybrid workers, who receives 911 notifications, and what fees it charges for E911. RingCentral, for example, lists an E911 service fee among the charges added to its plans.
