The 6 Best VoIP Plans in 2025: Features and Pricing Compared

Our research and testing have found that RingCentral Advanced is the best VoIP provider plan on the US market. We think it’s a great all-around solution due to its attractive call management, team communication, and best-in-class staff training features. Better yet, it has the widest range of external app integration support and a competitive price point.

Still, RingCentral might not be suited to all operations, especially if you want a cheaper, streamlined phone system for a small business. You’ll find each of the five other top-rated VoIP provider plans on this page suited to specific needs, so keep reading to find one made for you.

The Best VoIP Phone Provider Plans in 2025

According to our detailed research, the following suppliers offer the best VoIP provider plans available in the US for 2025:

1. RingCentral Advanced

Best Overall VoIP Provider Plan in the US

Our research has shown that, overall, RingCentral Advanced is the best VoIP provider plan for US businesses, especially those after large-scale operational control. It scored incredibly well in all our research categories, including perfect scores for call management, software integrations, customer support, and more.

Why is RingCentral Advanced the best overall VoIP provider plan?

An area where RingCentral dominates is with end-to-end communication tools tailored for medium-sized businesses. Namely, its call whisper and barge features let managers discreetly coach agents during live calls, critical for certain industries like customer service. And from the plans on this page, it is the only package that includes call whisper and call barge features by default.

The ability to look up call transcripts, make call recordings, and also monitor agent’s ongoing calls only adds to its appeal in this regard, too. Meanwhile, there’s automatic call screening which blocks spam calls using AI to help reduce wasted agent time by a reported 15–20% compared to Dialpad’s basic caller ID. That’s something that can help larger businesses with high call volumes.

While it offers native video conferencing support for up to 100 participants, we were impressed with its Microsoft Teams integration during our testing too, since it lets us launch video calls directly from Teams, unlike Zoom’s standalone app (although, if you opt for Zoom Phone, you can use its integrated video platform, so that might not be so much of an issue).

We found RingCentral Advanced’s customizable call routing was also more developed than some provider plans, allowing for rules based on time zones, caller history, or department. These features are missing in GoTo Connect’s base Phone System plan.

Finally, knowing that RingCentral Advanced comes with more ready-made integrations than any provider is another very appealing aspect of its general utility. With over 300 helpdesk, workspace, email, conferencing, and messaging platforms, you should be able to unify your comms and easily hold customer data no matter what software your team already uses.

Are there any downsides to RingCentral Advanced?

More expensive than alternatives

Like 8×8 Work, RingCentral Advanced‘s pricing can be on the higher side, ranging from $20 to $35 per user per month for its standard plans, with premium features available at additional costs. This could be a significant expense for SMBs or startups operating on tight budgets. Our alternative suggestions for less spending are the same as above:

• For the lowest price: Zoom Phone (from $10 per user per month)

Lacks free international calls

RingCentral Advanced is also a poor choice for free international calling since it has none outside of Canada included for US customers.

• For unlimited calling: 8×8 Work (14 to 48 countries depending on package) and GoTo Connect (over 50 countries on all of its paid plans) both offer extensive free calling packages as part of their packages. Organizations with extensive international communication needs will value these inclusions and avoid incurring extra fees.

No social media channel integrations

While RingCentral Advanced has a vast range of integration options, it lacks direct WhatsApp, Facebook or other social media tools included with your purchase. This forces eCommerce teams to purchase and use third-party apps on top of the RingCentral software.

• For native social media comms: Nextiva Engage ($40/user/month) includes WhatsApp and Instagram support by default.

2. Zoom Phone Regional Unlimited

Best For Affordability

In our overall standings, Zoom Phone Regional Unlimited came a close second to RingCentral Advanced by bringing an extensive range of features while improving on RingCentral’s key area of weakness: pricing. 

Zoom Phone has three affordable plans costing either $10 (for US & Canada Metered calling), $15 (for US & Canada Unlimited Calling) or $20 (for Global Select’s unlimited Calling within one of 49 non-US/CA countries) per user, per month.

Why is Zoom Phone Regional Unlimited the best VoIP provider plan for affordability?

With identical calling allowance and features to the Global Select tier, the $15 per user, per month domestic Regional Unlimited plan is our pick of Zoom’s packages for North American-based, medium-sized businesses.

That price makes it a solid choice if you’re looking for a functional VoIP system that won’t stretch out your wallet: it’s the cheapest plan of our top six picks for medium-sized businesses. To illustrate its affordability, for teams of 250 users, your business would be saving a cool $7,500 every month compared to RingCentral Advanced.

Plus, there’s no minimum user requirement like Dialpad (3) or different pricing based on user numbers like net2phone (which we assessed but unfortunately, it didn’t make our top six picks).

The price point isn’t everything, however: a worthy VoIP still needs the features to match. Something you may know about Zoom already is its video conferencing prowess, and with the Phone Regional Unlimited plan, every user can host 500 participants per meeting, which is double the limit of GoTo Connect’s Phone System plan and five times RingCentral Advanced’s limit.

It has plenty of useful in-meeting tools, too, such as chat, annotations, reactions, and notes, as seen below, plus plenty of app-store add-ons for things like AI-generated engagement scores, talk time, and coaching tips.

We found the Zoom One Portal app, which houses Zoom Phone, to be extremely easy to use, too. Testers were enamored with its well-signposted layout which means they could find any tool without difficulty.

There are notable features not found on other competitor plans discussed on this page, too. For instance, Zoom Phone Regional Unlimited has functionality for call queues that prioritize high-value clients (e.g. VIP customers who can skip hold times), a feature GoTo Connect restricts to higher tiers.

And should you need an international calling allowance, Zoom Phone Regional Unlimited lets you buy an add-on for $10/month. This allows all users the ability to make international calls to more than 15 countries and regions, which isn’t possible with providers like Dialpad and Nextiva. Packages from 8×8 Work and GoTo also offer international calling but it given their pricing isn’t as transparent as Zoom Phone, it is more difficult to assess what price you’ll be paying for the pleasure.

Are there any downsides to Zoom?

Lack of advanced analytics

Zoom does not offer advanced analytics tools such as real-time reporting, predictive analytics, and other dashboards, tables, and charts to dive into like VoIP-first companies.

• For analytics tools: Nextiva Engage provides real-time data on customer interactions and team performance for similar costs, or you can upgrade with RingCentral Advanced or 8×8 Work and get even more data at your fingertips like call quality, user activity, and system performance.

3. 8×8 Work

Best VoIP Provider Plan For International Calling

8×8 Work is up there with the best VoIP provider plans for US businesses, earning near-perfect marks in several assessment areas. Crucially, to earn the title of best provider for international calls, its packages automatically include unlimited calling to a wide variety of countries.

Better still, it boasts all the features we know to be most important for productive comms with customers and clients, from ring groups and call queues to big-name CRM integrations and compatibility with a range of plug-and-play desk phones. 

What makes 8×8 Work the best VoIP provider plan for international calls?

To make it our pick for international calling, 8×8 Work allows for unlimited minutes to up to 48 countries, as well as localized numbers in over 100+ countries, too. That means, if you had an EU customer, for example, they could dial a Paris-based phone number instead of a US toll-free line.

By default, 14 countries are included, so you’ll have this minimum number no matter what plan configuration you opt for. These countries are: Australia, Canada, France, Germany, Ireland, Italy, the Netherlands, New Zealand, Puerto Rico, Spain, Sweden, Switzerland, the United Kingdom, and domestically in the United States.

8×8 also matches Zoom for the number of video meeting participants with 500 per call, ahead of the likes of RingCentral Advanced (100) and GoTo Connect Phone System (150), which is appealing for globally dispersed teams that need to have regular conversations. We found using its video conferencing software easy to employ too, with clear signposting of buttons to invite participants and enter/exit.

8×8 Work’s security features also impressed us. With multiple compliance certifications, multi-factor authentication, password rules, and TLS/SRTP encryption, 8×8 Work does a lot to ensure your company’s calls and data are kept under lock and key from cyber attacks, which we understand to be a major concern of medium to large businesses.

And 8×8 Work has some of the best customer support options and availability, with a 24/7 live chat function and phone line for any out-of-hours issues. The international theme continues, too, since this support is multilingual, including major languages like Hindi and Mandarin, unlike RingCentral’s English/Spanish-only teams. Email support is also available for any less time-sensitive queries.

Are there any downsides to 8×8 Work?

Unpredictable pricing (and reportedly expensive)

While 8×8 Work offers a comprehensive suite of features, it lacks transparency around pricing. If you are a business running fine margins, this could risk overspending if you aren’t fully aware of all potential costs.

8×8 Work previously showcased its plans too, though now restricts this to certain webpages rather than on its main pricing page, which may suggest a shift away from the X-series plan structure (X2 to X4 shown in the pricing table above) evident in years before 2025. If these plans are still in play, they were reportedly quite expensive, ranging from $24 to $44 per user per month.

• For transparently cheaper pricing: We recommend Zoom Phone Regional Unlimited since it costs just $15 per user, per month and has clear pricing for any add-ons or other tier packages.
• For international calling at potentially lower cost: GoTo Connect Phone System also supports international calling to up to 50 countries and costs $26 per user, per month (although you may need to pay for international calling, as GoTo is unclear about this).

Comparatively limited hardware compatibility

While it works with two major hardware brands according to our research, products from Yealink and Poly, 8×8 Work only allows for the hardware it certifies, forcing businesses to replace existing devices if they don’t fit the bill. This could add even further spending, in what would be an unnecessary expense with alternative VoIP provider plans.

• For wider hardware compatibility: RingCentral Advanced supports a wide range of hardware, including Cisco and Polycom, allowing businesses to use existing devices. Meanwhile, the GoTo Connect Phone System plan also offers BYOD (Bring Your Own Device) flexibility, reducing upfront costs for businesses changing phone systems.

4. GoTo Connect Phone System

Best VoIP Provider Plan For Growing Businesses

GoTo Connect’s Phone System plan is our favorite VoIP system for growing businesses. After all, when growing a business, you have to make sure you’re getting as much as you can for as little money as possible.

Why is GoTo Connect Phone System the best VoIP provider plan for growing businesses?

There are many facets in which GoTo can help save you money. For starters, GoTo’s Phone System plan secures unlimited domestic and international minutes to over 50 countries for a relatively minuscule price tag; no other provider offers as many international calling locations (albeit, GoTo notes this international allowance is with “specific plans” so you’ll need to contact them to see if you are eligible). 

For teams that already have existing desk phone brands that they use for calls, or have staff working across multiple different locations and need wide hardware compatibility to cover that, then GoTo is the best bet in this regard, too. It operates a ‘Bring-your-own-device’ approach that helps cut hardware costs since businesses can have existing desk phones from the likes of Cisco and Polycom repurposed without any issues rather than buy new ones.

And GoTo is a VoIP system that can help you communicate with potential customers and clients professionally. With GoTo Connect, you can set up a virtual receptionist, customizable on-hold music, recorded greetings, and voicemail capability to give callers a polished experience whenever they get in touch.

Elsewhere, for businesses that need it, GoTo Connect includes e-fax capabilities allowing teams to send/receive faxes without investing in physical fax machines (often costing $500+ for fax hardware and ongoing maintenance costs). All other provider plans on this page don’t include e-fax capabilities by default (and only Dialpad offers it as an add-on).

As your business grows further, you won’t be restricted either since it has an unlimited user limit and further call management features on its higher-cost plans, from means it’s a scalable system. Plus, if you need social media integrations for things like WhatsApp campaigns, as is possible with Nextiva Engage, you can upgrade to GoTo’s next cheapest plan (GoTo Connect CX).

Are there any downsides to GoTo Connect Phone System?

Lacking some advanced call management and training features

While GoTo Connect Phone System includes standard call management functionalities, it lacks some advanced features such as predictive dialing, AI-driven call analytics, or call routing. It also is missing call whisper or call barge tools.

• For advanced call management tools: Providers like Nextiva Engage and Dialpad Pro offer these advanced AI routing capabilities, while both 8×8 Work and RingCentral Advanced have some more advanced analytics and predictive dialing you are willing to spend a little more.
• For call whisper and barge: Both 8×8 Work and RingCentral Advanced offer these features, with the latter being the better option overall.

No automatic call screening

GoTo Connect Phone System lacks automatic call screening which uses AI to block spam or nuisance calls.

• For automatic screening: RingCentral Advanced includes automatic screening which classifies callers as “nuisance” or “priority” based on behavior. Similarly, Dialpad Pro offers AI-powered spam detection.

5. Nextiva Engage

Best VoIP Provider Plan For eCommerce and Social Media

Nextiva Engage is the only option if you want to pair your VoIP phone system with a best-in-class social media toolkit. That’s because this plan offers native integrations with WhatsApp, Instagram, and Facebook, allowing businesses to manage customer inquiries across multiple channels from its single platform.

Why is Nextiva Engage the best VoIP provider plan for eCommerce and Social Media?

When looking at the competitor plans on this page, no other VoIP providers can offer the same suite for omnichannel engagement as Nextiva Engage. While you could get social media integrations through a third-party tool integration, namely with RingCentral Advanced and 8×8 Work rather than Dialpad Pro and GoTo Connect Phone System, this may come at additional cost and isn’t as seamless as everything being embedded directly.

By offering more channels than any other provider plan at this level, Nextiva Engage also has more unified analytics that track customer journeys across calls, chats, emails, and social media. While this won’t be relevant to all industries, eCommerce and social media-driven sales teams should find this 360-degree omnichannel makeup incredibly useful for identifying trends, optimizing workflows, and improving customer satisfaction in the long run.

In terms of calling, Nextiva Engage has some features that set it apart from others, too.  Like Zoom Phone Regional Unlimited, businesses can create custom call queues with priority routing for VIP customers, bettering the likes of GoTo that can’t. This can help retain your repeat customers’ service. Even better, we’d say Nextiva Engage offers more detailed queue analytics for areas such as wait times and agent performance compared to RingCentral Advanced.

Nextiva also offers real-time, AI-driven sentiment analysis like Dialpad Pro, to detect customer frustration (from things like raised tones) to alert supervisors. This isn’t possible with  RingCentral Advanced and 8×8 Work at the time of writing, which instead rely on post-call surveys or manual feedback.

Are there any downsides to Nextiva Engage?

More limited integrations

Offering around 20 ready-made integrations across CRM, helpdesk, and productivity tools, Nextiva is a little more limited than other providers in this regard. It has big names like Zoho, HubSpot, Salesforce, Microsoft and Google covered but beyond that, you’ll be struggling to get proper integration with Nextiva.

• For wider integration options: RingCentral Advanced is the leader here with over 300+ VoIP-related integration options. 8×8 Work has triple the amount Nextiva offers, too.

No international call allowance

Nextiva Engage does not include international calling—calls outside the US are charged per minute instead based on the specific country. There is no possibility to purchase an unlimited international calling add-on package, either, so you’ll always call with per-minute rates.

For unlimited international minutes: 8×8 Work includes unlimited calls to 48 countries, making it the clear leader for global teams. GoTo Connect also offers unlimited calls to 50+ countries but it’s unclear if there are extra costs for this package on top of Phone System given GoTo says it only applies to “certain packages”. RingCentral and Zoom also offer unlimited international calling as an add-on for an additional fee per month.

No call whisper or call barge

Nextiva Engage does not support call whisper or barge tools for live coaching.

Alternatives: RingCentral Advanced and 8×8 Work include both of these features, while Dialpad Pro offers AI-coaching insights to compensate for its missing features.

6. Dialpad Pro

Best VoIP Provider Plan For SMBs

Rounding out our list of the top six provider plans for medium-sized businesses is Dialpad Pro. It’s the final plan to score above 4/5 from our assessment criteria (we analyzed a further four plans for this size of business) and provides ample appealing features for small and medium-sized businesses (SMBs) in the US.

Why is Dialpad Pro the best VoIP provider plan for SMBs?

Dialpad Pro combines AI-driven efficiency, scalability, and cost-effectiveness to meet the unique needs of SMBs. Looking at costs, only Zoom Phone Regional Unlimited is cheaper than Dialpad Pro from the provider plans on this page. Meanwhile, for example, a 50-person SMB using Dialpad Pro would save $9,000/year compared to Nextiva Engage, while gaining access to arguably the most advanced AI tools of any VoIP provider on this page.

That includes advanced call routing with AI-driven prioritization, where agents are actively chosen based on which is most qualified for a specific task based on skills, availability, and perhaps most impressively, the details within a specific customer’s history with your team. By comparison, the likes of RingCentral and GoTo rely on more basic rules since their AI isn’t applied to call routing, with only Nextiva matching this functionality.

When implemented, its conversational AI chatbot can also let customers escalate calls so that they can speak to a human agent via voice or video. The AI then applies those IVR routing decisions you’ve set up.

Dialpad has further AI benefits we couldn’t find in other competitors, too. It offers live coaching and speech analytics during calls for one. This could be prompted to upsell about a certain product area or de-escalate issues when there is noticeable tension from its sentiment analysis.

Similarly, we found its AI tools could fully integrate with CRM platforms like Salesforce and HubSpot. In practice, this allows the AI to do things like auto-populate customer data during calls, and we couldn’t find evidence of any other provider plan here being able to do the same.

We’d argue that Dialpad’s AI-powered document management (e.g., auto-filing faxes by client) is more efficient than GoTo and Nextiva’s system, too, should you need e-fax capabilities (albeit, this is only available as an add-on with variable pricing depending on your plan).

And very useful for those SMBs with too much work and too little time, Dialpad Pro’s AI also helps create automated action items and task tracking to keep you on top of everything. It extracts action items from calls (for example, following up with a client next Tuesday) and creates to-do lists automatically, reducing manual note-taking or data entry. RingCentral Core and 8×8 Work both have task management tools, but they rely on manual input.

Are there any downsides to Dialpad?

Lack of advanced training tools

While offering AI coaching support, Dialpad Pro doesn’t have call whisper and call barge functionality to let human managers do the same. This blocks the ability for live agent coaching and real-time feedback during calls, and in this sense, it could be less suitable for customer service or sales teams.

• Alternatives: Both RingCentral Advanced and 8×8 Work include call whisper and barge, enabling managers to discreetly guide agents during live calls.

Lack of social media integrations

Dialpad Pro does not integrate with WhatsApp, Facebook, or Instagram for customer engagement.

• For social media tools: Nextiva Engage has native WhatsApp, Instagram, and Facebook integrations, making it ideal for eCommerce and social media-heavy businesses.

No global calling minutes

Like Nextiva Engage above, Dialpad Pro doesn’t offer international calling packages. That means you’ll always face a per-minute charge rather than have them included in your monthly cost (either by default or with an add-on).

For unlimited international calls: The obvious choice is 8×8 Work which includes unlimited calls to 48 countries by default in its packages. You can also opt for GoTo Connect Phone System, which offers unlimited calls to 50+ countries, though it isn’t clear if there are extra costs for this package since it only applies to “certain packages”. If you are happy to purchase an add-on for a monthly fee, RingCentral and Zoom can also provide this service.

The Benefits of a VoIP Phone System

So, why invest in a VoIP phone system for your business? There are plenty of reasons to do so, but these are the most impactful:

How to Choose a VoIP Phone Services Provider

With several VoIP providers available, determining the best fit for your business can be challenging. Focus on these key factors to make an informed choice based on your business wants and needs:

1. Pricing

The cost of a VoIP system depends largely on the number of users, as providers typically charge per user, per month. Providers also offer tiered pricing plans, with higher tiers offering more advanced features. We suggest working out an all-in, per-user figure so you can compare fairly, as list prices aren’t the total cost:

• Typical spend: Most mid-tier seats land around $15–$35 per user/month; omnichannel or advanced analytics suites are often $40+.
• Add-ons to check: International bundles, toll-free minutes, contact center features (whisper/barge, wallboards), large-meeting capacity, call recording storage, SMS/MMS.
• Contract shape: Annual billing lowers price but reduces flexibility; some plans enforce seat minimums (e.g., three users).
• Taxes & fees: Expect telecom surcharges on top; ask vendors for an estimate on your ZIP/state.

For provider-specific pricing for some of the cheaper plans on the market, read our standalone pricing pages for the likes of Zoom Phone and Net2Phone.

To reduce costs, consider these strategies:

• Opt for a provider plan with a lower price per user.
• Select a lower-priced tier that meets your essential needs.
• Pay annually, as providers often offer discounts for upfront payments.

Questions to guide your decision:

• What features does your business need? This will help identify the right tier. SMBs may require fewer tools, for instance.
• How reliable is the provider’s service and support? Check reviews or research to ensure dependable service.

2. Uptime, call quality and network readiness

Great software still sounds bad on a weak network. Verify reliability and prep your setup. Here are some areas to consider:

• SLA & history: Ask for 12–24-month measured uptime and credits for breaches; check status page history.
• QoS basics: Prioritize voice (RTP) traffic, consider a voice VLAN, and prefer wired for call-critical roles.
• Target health: Aim for <150 ms one-way latency, low jitter, and <1% packet loss during peak.
• Edge configuration: Follow vendor SBC/firewall guidance; disable SIP ALG if required.
• Real tests: Place concurrent test calls at your busiest hour and capture MOS/call-quality stats.

Questions to answer: Can our network support our peak concurrent calls? What’s the vendor’s SLA, and who owns incident response?

3. Security, compliance and data

Most VoIP brands, and all the options on this page, offer strong security credentials, meaning you shouldn’t be worried about your data. However, that doesn’t mean a cyber attack can’t happen or that security levels won’t change in the future.

Similarly, depending on your industry, you may require certain measures to comply with local, national or international laws. Here are some areas to consider when selecting a VoIP provider plan:

• Access & identity: Require SSO (single sign-on) via SAML (Security Assertion Markup Language) or OIDC (OpenID Connect), enforce MFA (multi-factor authentication), use RBAC (role-based access control), and capture audit logs; bonus points for SCIM (System for Cross-domain Identity Management) to auto-provision/deprovision users.
• Encryption & transport: Insist on TLS (Transport Layer Security) for signaling/APIs and SRTP (Secure Real-time Transport Protocol) for voice/video media; confirm encryption at rest for recordings and transcripts.
• Certifications & regulatory: Look for SOC 2 Type II (Service Organization Control), ISO/IEC 27001, and, where relevant, HIPAA with a BAA (Health Insurance Portability and Accountability Act/Business Associate Agreement); ensure a DPA (Data Processing Agreement).
• Data governance: Define retention for PII (personally identifiable information), call recordings, voicemails, SMS/MMS, and transcripts; support eDiscovery/legal hold, bulk export on exit, and data residency (US/EU/UK). Ask for backup RPO/RTO targets (Recovery Point/Time Objectives).
• Monitoring & endpoints: Prefer SIEM (Security Information and Event Management) integrations and anomaly alerts; allow IP allowlisting, device controls via MDM (Mobile Device Management), and session/time-out policies for desktop/mobile apps.
• Incident response & AI privacy: Confirm breach-notification SLA (service-level agreement), scope of security support, and whether AI features (transcription/summarization) offer redaction and opt-outs from model training or third-party processing.

4. Key VoIP features

The right features can significantly improve your business operations, too. Depending on your industry requirements, you may need or want different features.

For instance, expanding businesses in sales may require coaching features to help new staff navigate calls in their first few weeks. Meanwhile, retail or hospitality businesses might look for a VoIP with an Interactive Voice Response (IVR) to direct customers to the right channels.

In any case, here are some essential features to look for in a top-line VoIP plan:

• Call routing & IVR: Drag-and-drop menus, skills/time rules, queues + callbacks to cut transfers and wait times.
• Spam screening & voicemail preview: Block nuisance calls and triage messages before answering.
• Coaching & QA: monitor/whisper/barge, recording + transcription; AI summaries to reduce note-taking (whisper/barge often needs a higher or contact-center tier).
• Channels: Voice, SMS/MMS, team chat, video from the dialer; optional social inbox (WhatsApp/Instagram/Facebook) for sales/support (larger meeting caps may need a higher video tier or add-on).
• Analytics & productivity: Live dashboards, trend reports, QA scorecards, auto-logging to CRM; ask for sample reports and export options.
• Integrations & devices: Native Salesforce/HubSpot/Zendesk + Google/Microsoft, APIs/webhooks; softphone/mobile with call-flip, certified/BYOD desk phones, zero-touch provisioning.
