The 10 Best VoIP Services for Business in 2024

No Contracts — Ooma offers a pay-as-you-go pricing model, allowing you to sign up without committing to an annual contract. This is perfect for those new to VoIP, hesitant about switching from a traditional system, or are seeking a short-term solution.

You’ll have access to advanced calling features while retaining flexibility in case your circumstances change.

Easy Installation — Ooma offers a simple DIY installation process, so you can easily set up the service using your existing hardware.

There’s no need to call an engineer or purchase new handsets because Ooma VoIP works with analog phones and smartphones. You can also opt for an Ooma IP phone, which is currently available as a buy one, get one free deal.

Free Number Porting — Another way Ooma simplifies its setup is by offering free number porting. This means you can keep the same business number as your previous system, minimizing disruption for any customers trying to reach you.

Ooma offers three pricing plans for businesses of various sizes and budgets. Below, I’ve outlined each plan’s costs and features:

• Office Essentials — Offers a range of 50 advanced call management features, which is generous compared to other entry-level plans on this list. It also supports unlimited domestic voice calling, but it doesn’t offer video conferencing, like 8×8’s cheapest plan, for instance.
• Office Pro — Ooma’s mid-tier plan adds video conferencing to the mix with up to 25 participants; note that this is not as many participants as Vonage (200) or Nextiva (250) for the same plan tier. It also offers call recording and the ability to make and receive calls from the desktop softphone app.
• Office Pro Plus — Ooma’s top-tier plan increases the video conferencing capacity to 100 participants. This is still less than the cheaper plans of other providers on this list. However, for $29.95 per month, it’s a good deal for smaller teams. It also introduces online appointment scheduling and CRM integration.

Ooma is a great option for businesses that need a professional VoIP system but don’t want to commit to a long-term contract. It has an easy setup process and offers flexible contracts. This makes it ideal for businesses that require a phone line for temporary projects, such as seasonal businesses or pop-up stores. You can cancel the service at any time because it operates on a monthly rolling contract.

However, it’s worth noting that monthly pricing can end up being more expensive than annual plans. For instance, most VoIP systems offer a discount of $5-$10 per month when billed annually when compared to monthly billing.

Advanced Integrations — Most large enterprises will have a developed software stack to record and track the high volumes of inbound and outbound calls made each day. Therefore, it makes sense to adopt a phone system that can integrate with existing software. The RingCentral app offers hundreds of integrations with commonly used communication, productivity, and CRM tools like Salesforce, Microsoft 365, and Slack.

Global Coverage — In addition to offering unlimited calling within the US and Canada, RingCentral allows you to set up additional international virtual numbers in 99+ countries for just $5.99 per month. If you prefer to work with traditional phone lines, you can also set up a PSTN line in 45 countries.

Robust Security — It’s crucial for large enterprises to opt for highly secure VoIP systems. RingCentral complies with various global security regulations such as HITRUST, GDPR, PCI, and HIPAA. Additionally, it is hosted on a secure cloud platform, providing peace of mind that your data is safe.

RingCentral offers three pricing tiers for a range of business sizes and budgets. Below, I’ve outlined what each plan includes and what it costs:

• Core — A suitable fix for small businesses, with features such as unlimited domestic calling, SMS and MMS, visual voicemail, IVR, unlimited video meetings, up to 100 participants with AI meeting transcription, summaries, and insights, SSO, Quality of Service analytics, and integration with Google, Microsoft, and custom platforms via API.
• Advanced — For more advanced needs, this plan expands on the Core plan’s features with auto call recording, advanced call monitoring and handling, CRM integrations, cloud storage back-up, and custom roles and permissions.
• Ultra — Building upon the previous plans, this plan offers customizable business analytics, unlimited AI video meetings for up to 200 participants, and unlimited storage for files and recordings.

RingCentral is a great fit for large businesses as it can handle complex communication needs at an enterprise level. It provides unlimited video calling, advanced call handling features, global calling, and strong security features.

Although the Core plan targets smaller businesses, at $30 per month it is relatively expensive when compared to competitors’ entry-level plans. For example, Ooma offers a plan at $19.95 per month and Vonage at $13.99 per month.

Call Queue Management — When your call volume outweighs the number of available agents, efficient call routing and queueing can alleviate the pressure. Call queuing keeps multiple callers on the line, while routing can pass calls through to alternate numbers, recorded messages, or voicemail if an agent is not available.

Detailed Call Analytics — MightyCall provides monitoring features, call barging, call recording, and call intercept so that you can analyze performance and protect your staff. Additionally, you can use previous calls for training purposes to standardize best practices.

Multi-Level Interactive Voice Response (IVR) — Multi-level IVR is an advanced automated menu that greets callers and directs them to the right department or language. This makes MightyCall an ideal phone system for larger businesses with various teams sharing a central phone line.

MightyCall offers four pricing plans for various business sizes and budgets. Below, I’ve outlined what each plan costs and includes:

• Core — Advanced virtual phone system with unlimited calling and messaging, making it more generous than one of its closest price competitors, Phone.com. You get 2 business phone numbers integrations (also more than Phone.com), and API access.
• Pro — This is a relatively well-priced call center solution. It has all Core features plus a supervisor workspace, live call monitoring, analytics, and reporting.
• Power — An auto-dialing call center plan with all Pro features, plus a preview dialer, a progressive dialer, and a dedicated account manager.
• Enterprise – Custom plan with all Power features, plus a predictive dialer, SIP trunking support, and custom integrations.

MightyCall is well-suited for larger businesses and call centers that handle high incoming call volumes across multiple departments.

It provides an impressive set of inbound and outbound calling features, ideal for customer service teams and external communications. It also prioritizes security, which is key for dealing with customer data.

However, it lacks certain features, like video calling and team chat, that would make it suitable for use as an internal team VoIP system, like Vonage and Ooma.

All-in-One Platform — Manage your website live chat, messaging apps, social media channels, and online reviews from one central location, along with your voice and video calls.

Flexible Hardware — Choose whether you’d like to operate Nextiva from mobile or desktop apps, conference phones, or VoIP desk phones.

CRM Integration — Nextiva integrates with leading CRM platforms like HubSpot, Zendesk, and Salesforce to help you provide well-informed customer service and promote consistency across all your communication platforms.

Nextiva offers four pricing plans for various business sizes and budgets. Below, I’ve outlined what each plan costs and includes.

• Digital — Supports start-ups wanting to centralize communication with customers on diverse channels — including live chat, messaging, social media, reviews, and digital helpdesk. This does not include voice calling like Ooma and Vonage, which are also cheaper.
• Core — A small team solution for voice and video calling, SMS, screen, and file sharing. However, the 250-participant limit on video conferencing is rather generous.
• Engage — A solution for growing teams with higher call volume, including features such as reporting, toll-free numbers, call queuing, and integration with MS Teams.
• Power Suite — For sales and customer service-level call volume, this plan offers advanced IVR, intelligent call routing, and a unified team interface and supervisor dashboard to better manage teams of agents.

Nextiva is ideal for contemporary businesses that do not solely rely on voice calling to communicate with their customers. It recognizes that multi-channel communication is the new standard as more customers prefer to interact with businesses via messaging or social media. If you’re seeking an omnichannel solution, Nextiva is a great choice.

That said, it’s important to note that its entry-level Digital plan does not support voice calling. If you want to combine messaging platforms and voice calling, you’ll have to subscribe to the Core plan, which is pricier than some competitors at $30 per month.

Shared Numbers — Combining a shared inbound sales number with an IVR system allows multiple team members to handle incoming calls through the same number. This ensures that no lead is missed and supports collaboration on customer follow-ups. Using one number also ensures that clients and prospects receive a consistent brand experience.

AI Transcripts — OpenPhone’s AI call transcripts and summaries can record your sales and recruitment calls and build a paper trail of interactions. This is especially important when discussing quotes and proposals.

CRM Integration — OpenPhone integrates with leading CRM systems like HubSpot and Salesforce, allowing you to track interactions with leads in a centralized database linked to your phone system. When making calls, you can easily view customer profiles from your CRM.

OpenPhone offers three pricing plans to suit a range of businesses and budgets. Below, I’ve outlined what each plan costs and includes:

• Starter — A straightforward plan for essential VoIP calling, including one new local or toll-free phone number per user, calling and messaging to the US and Canada, and voicemail transcripts.
• Business — With more advanced features such as OpenPhone AI, group calling, call transfers, HubSpot and Salesforce integration, phone menus, auto call recording, and analytics and reporting, in addition to everything on the Starter plan.
• Enterprise — If your needs are more complex, the Enterprise plan offers everything from the Business plan with the addition of a custom contract and pricing, a dedicated account manager, priority support, and an audit log.

OpenPhone is well-suited to client-facing calling, such as sales, recruitment, or customer service teams. It easily integrates with CRM systems and offers a breadth of features to simplify the handling of inbound and outbound calls.

It’s less suitable for internal communication within teams as it lacks video calling, like 8×8 or Ooma.

Budget-Friendly Plans — With prices starting from just $4.96 per month, Voiply is the cheapest VoIP system I’ve encountered. This makes it ideal for smaller businesses and those prioritizing budgets.

Unlimited Calling — From its cheapest plan and up, Voiply supports unlimited calling in the US and Canada.

Basic Setup — Voiply’s simple, user-friendly interface allows you to set it up with minimal technical expertise. There’s no need for additional equipment as it can work with your smartphone or computer – as long as you have an internet connection.

Voiply offers three plans for various business sizes and budgets. Below, you’ll find the details on what each plan costs:

• Starter — This plan offers solo entrepreneurs unlimited domestic calling, a mobile app, a free local number, the ability to port an existing number, voicemail to email, and text messaging —  at the cheapest price point on our list for any plan.
• Advanced – Everything in Starter but better for small teams and still under $10, making it the most affordable mid-tier plan on this list. It includes the desktop app, supports up to 5 users, one new local and toll-free number, call blocking, custom auto attendants, ring groups, call recording, and conferencing.
• Premier — This is a more robust solution with all Advanced features, plus support for VoIP desk phones, analytics and reporting, and call queues.  While this is the cheapest plan of this tier on my list, it still offers a decent range of advanced functionality.

If you’re a small business owner or simply want to minimize telecom expenses, Voiply is a great budget-friendly solution.

Due to its price, it lacks advanced features like complex analytics, integrations, and video calling. However, if you’re simply looking for a VoIP phone line with unlimited calling, Voiply can provide this for less than $5 per month.

Customizable Phone Menus — The customized phone menu provides your customers with a top-tier calling experience, giving your business more credibility.

Business Phone Numbers — You can still take calls via your smartphone, but customers will have a different number. This can be a toll-free, local, or international number, depending on what works best for your customers.

Video Conferencing — You can host logo-branded virtual meetings that are protected with 256-bit encryption for 10-100 participants, depending on your plan. This means you can communicate face-to-face with your team and clients even when you’re geographically dispersed.

Phone.com has three tiers for various business sizes and budgets. Below, you’ll find the details on each plan:

• Basic — 500 minutes across the account, which isn’t as appealing as the unlimited calling of other similarly-price plans from Dialpad and MightyCall ($15 per month). You also get one number per account, video conferencing for 10 participants, 50 standard voice features, and access to mobile and web apps.
• Plus — Unlimited calling kicks in for this plan, and you’ll now get 1 number per user. Plus allows for 25-participant video conferencing, making it less generous than most other mid-tier plans, but it is cheaper. You also voicemail transcription.
• Pro — All Plus features, 100-participant video conferencing, call analytics, call recording, and CRM integration.

Phone.com is excellent for small businesses that want to present a professional image to customers calling with features like hold music, auto-attendants, and custom greetings without enterprise-level price tags.

If you’re needing a simple VoIP plan that supports cheap unlimited virtual calling I’s recommend Voiply instead. Phone.com’s unlimited minutes are only included from the Plus plan at $18.69 per month vs Voiply’s $4.96 per month.

Mobile App — Vonage’s mobile app provides remote teams with full access to the VoIP system from their smartphones, meaning they don’t need to be sitting behind a desk for seamless communication.

Collaboration Tools — It’s easy for your internal team to stay connected with features like team messaging, video conferencing, and integrations with Microsoft Teams and Slack.

International Numbers — You can add international numbers to your Vonage system so that your business’s presence outside of the US remains authentic and trustworthy to international customers.

International numbers will still be connected to your business’s main phone number via the virtual receptionist, so your customers will be routed to the correct place when calling from abroad.

Vonage offers three pricing tiers for businesses of various sizes and budgets. Below, I’ve outlined each plan’s features and costs:

• Mobile — An affordable, straightforward mobile and desktop solution for unlimited domestic calling, SMS, MMS, and voicemail. There’s no video calling on this entry-level plan like 8×8, RingCentral, or Phone.com.
• Premium — Introduces unlimited video meetings with up to 200 participants, which is a lot more than Ooma’s 25 and for a lower price. It also offers team messaging, third-party integrations, and SSO.
• Advanced — In addition to the previous plans’ features, this plan offers on-demand call recording, visual voicemail, and call groups. It’s not as feature-rich as the other top-tier plans on this list, including those of a similar price point like Ooma and Phone.com.

Thanks to its collaboration features, global calling, and user-friendly mobile app, Vonage is the ideal flexible VoIP service for remote or hybrid teams.

However, its Mobile plan, while affordable, lacks key features like video calling and access to the VBC app center. Therefore, I’d recommend the Premium plan to access a fuller suite of features while still paying a reasonable monthly fee of $20.99. This is only slightly more than Ooma ($19.95/mo) and Nextiva’s ($20/mo) entry-level plans.

AI-Powered Transcriptions — Dialpad’s AI provides real-time transcription of your calls and meetings.

Customer Sentiment — You can analyze the overall sentiment of customer interactions, whether positive or negative. This will provide you with real-time actionable insights and can also be valuable for performance tracking and improvement.

Integrations — Dialpad offers an impressive suite of integrations, including leading CRM systems such as HubSpot and Zoho. These help you maintain a seamless flow when working across multiple platforms and personalize customer interactions.

Dialpad has three plans to choose from. Below, you’ll find the details on what each plan costs and includes:

• Standard — Dialpad’s entry-level plan offers unlimited calling and AI meetings with up to 10 participants, SMS, MMS, and team messaging, AI voicemail transcriptions, integration with Google and Microsoft, real-time analytics, and web and chat support.
• Pro — In addition to the Standard plan’s features, the Pro plan introduces 24/7 live agent support, CRM integrations, multiple numbers per account, open API, global SMS and local numbers for 70+ countries.
• Enterprise — By signing up as an enterprise customer, you’ll get a custom price plan that includes all the features of the Pro plan with 99.9% uptime, unlimited ring groups and office locations, dial-by-extension, SSO integrations, data retention policies, and priority live agent support.

Dialpad is suitable for those seeking an affordable phone plan with advanced AI features to enhance customer interactions and agent performance.

While it does offer international calling, it’s not the most extensive coverage compared to competitors such as 8×8. For this reason, it may fall short for larger businesses with a global reach.

International Calling — Depending on your plan, 8×8 includes unlimited calling to 14-48+ countries, making it ideal for those frequently calling abroad.

Multi-Language Support — Its interface is also available in multiple languages, which is perfect for larger enterprises with branches in different countries. The contact center’s chat function can also handle live translation so that agents can help customers in their native language, including English, Russian, German, Japanese, Spanish, French, Chinese, Portuguese, Italian, and Polish.

Data Compliance — When working across borders, compliance can become complicated. Luckily 8×8 is compliant with international regulations like GDPR.

8×8 no longer advertises its pricing, and you will need to contact its sales team directly for a custom quote. It does offer five plans, and this is what is included with each one:

• X2 – Unlimited voice calling to 14 countries, HD video and audio conferencing for up to 500 participants, SMS, MMS and team chat, Microsoft Teams integration
• X4 – Everything in X2, plus unlimited calling to 48 countries, 8×8 frontdesk for receptionists and operators, supervisor analytics, and monitor, whisper and barge.
• X6 – All X4 features, skills-based routing, IVR, call recording, reporting and analytics, CX journey mapping, choice between metered and unmetered call bundles
• X7 – Everything in X6, plus omnichannel support for social media, chat, email, SMS and video, and co-browsing
• X8 – All X7 features, plus quality management and speech and text analytics.

8×8 offers a robust VoIP solution for larger businesses with globally distributed teams and client bases. It provides broader support for international calling than any of its competitors and generous capacity for video calling.

One drawback is that its pricing is not available online, making it difficult to determine whether it offers good value for money.
