Google Voice is the cheapest VoIP phone service, but there are loads of high-quality, affordable options on the market. Considering both the short-and longer-term costs of services, our research suggests that these are the eight cheapest VoIP phone services in 2023:
Does Scalability Matter?
VoIP scalability refers to how effective a system will be at meeting your business’s future needs. When researching the cheapest VoIP services on the market, we found that scalability had a massive impact on price. The cheapest systems to set up initially, aren’t always the cheapest in the long run. When a telephone system is able to evolve alongside your business, you’ll be saved the money and hassle involved with installing a new product, or expensive add-ons, later down the line. Comparing custom price quotes can give you the full picture of costs for your exact business needs.
1. Google Voice – Cheapest VoIP System Overall
- Prices from: $10/user/month
During our examination of the prices for the top internet phone providers, we found that Google Voice delivers the cheapest VoIP phone service for businesses. In fact, with plans starting from $10 per user per month, the system’s starting price is head and shoulders below its rivals, and its overall offering isn’t bad either.
The cloud-based phone system allows businesses to make and receive domestic and international calls, and its simple usability helped it to secure a solid customer score of 4.4/5. Aside from its obvious name recognition and ease of use, the system really comes into its own with its strong set of security features. Google Voice encrypts all consumer information and stores it in world-class data centers for safekeeping. When compared with services like Vonage, which only rank 3/5 for security, Google’s commitment to security is pretty extensive.

However, being the cheapest VoIP provider means it’s bound to come with a few drawbacks. While the service’s security features are strong, the rest of its feature package is found to be lacking. The system even bypasses basic communication and management tools like call queue, call barge, and call recording, making it a poor choice for quite a few businesses. Unless you have fairly basic VoIP needs, we’d recommend you go for well-rounded systems like Ring Central or Dialpad.
See how it compares in our guide to the top Google Voice alternatives.

What we like
- Cheapest VoIP phone service we reviewed
- Ranked #1 VoIP for security features
- User-friendly interface
What we don’t like
- System isn’t very scalable
- Limited business features
- Poor customer support
2. Dialpad – Great for Startups
- Prices from: $15/user/month
Dialpad is the second cheapest VoIP phone service we researched, with its cheapest plan weighing in at $15 per user, per month. This affordable price point makes it perfect for startups and smaller businesses that are looking to stay connected while keeping overheads low. We also found it to be a decent all-around VoIP system that includes all of the call features and collaboration tools needed to lift your business off the ground.
This sophisticated VoIP system can do far more than manage inbound and outbound calls. Unlike Google Voice and GoTo, Dialpad has a sterling set of business features, including an advanced voice intelligence (Vi) tool, which transcribes your conversations in real time. There is also a number porting tool that will allow businesses to use their existing phone number. For the modest price you’ll be paying for the service, this is a pretty impressive tool-kit.
The provider recently launched an AI coaching hub for early adopters, which makes it even easier for managers to track performance, streamline onboarding processes, and improve customer experiences (see below).

Unfortunately, DialPad’s low monthly fees means there are a few downsides. International calls aren’t included in the systems start-up costs, meaning that businesses making calls outside the US will be subject to additional fees. The option isn’t able to grow well with businesses either, receiving a score of 3.3/5 for scalability, this is because it lacks call monitoring and call flow designer on plans that are below the Enterprise tier. Due to the costs this is likely to incur businesses down the line, we think Dialpad’s overall value for money isn’t as strong as other solutions like Net2Phone or Zoom.
What's new for Dialpad?
Dark Mode – You can now switch Dialpad’s interface between Light and Dark Mode, or set it to change automatically based on your systems preferences. (August 2023)
Ai Coaching Hub – Gain a complete overview of your team’s performance and identify which teams and agents may need additional support. (June 2023)
In-Queue Callback Setting – Allow customers that requested a call back to ring your first with Dialpad’s new in-queue callback setting. (June 2023)
Highlights
- Advanced business features
- Easy to set up
- Great customer support options
Key Features
- Unlimited domestic calls
- AI keyword tracking
- AI voice transcription
- Business SMS's
- Three pricing tiers offered
- Cheapest plans cost $15 per user, per month

| Price | Users | Unlimited calls in US | Video conferencing | 24/7 support | Call recording | Call monitoring | ||
|---|---|---|---|---|---|---|---|---|
 | | | ||||||

| $15/user/month | $25/user/month | Custom | ||||||

What we like
- Second cheapest VoIP phone service we reviewed
- Great customer support options
- Sophisticated AI features
What we don’t like
- The system isn’t very scalable
- Poor external connections
- International calls cost extra
3. Ooma – Great Customer Experience
- Prices from: $19.95/user/month
With competitive pricing, a decent range of business features, and round-the-clock customer support, Ooma is a simple yet practical VoIP solution. According to Tech.co’s own independent research, which compared telephone services against hundreds of data points, Ooma is the most reliable VoIP provider your business can go for, on top of being the third cheapest VoIP phone service we reviewed. And don’t just take our word for it, with an impressive customer rating of 4.4/5 from clients, the system is clearly a favorite among businesses too.
Ooma Call Analytics Feature, source: ooma.com
There are, however, some limitations with the service. If you’re serious about data security, Ooma’s features probably won’t cut the mustard. All plans lack basic security tools like multi-factor authentication and user permissions, and Ooma doesn’t display compliance certifications on its site either.
For many businesses, Ooma’s lackluster commitment to data security will be a dealbreaker. But if this isn’t your business’s top priority, we discuss its pricing plans below.
What's new for Ooma?
Private Accounts – This feature lets users split their Ooma account into two different phone lines for different purposes, and assign different controls and ringtones to each account. (February 2023)
Highlights:
- Unlimited calling in US, CA, MX, PR
- 35+ features included at no extra cost
- Easy DIY installation
- 24/7 support
Key features:
- "Customer Success Managers" for support
- Multi-level virtual receptionist
- Free smartphone app with SMS/MMS messaging incorporated
- Starts from $19.95/user/month
- Cheapest plan is feature-rich
Ooma pricing
Ooma offers three distinct plans: Office Essentials, Office Pro, and Office Pro Plus. Learn more about them in our comparison table below:
| Price | Users | Unlimited calls in US | |||
|---|---|---|---|---|---|
| | | | | | |
| Ooma Office | Ooma Office Pro | Ooma Office Pro Plus | Ooma Enterprise Standard | Ooma Enterprise Enhanced | Ooma Enterprise Call Center |
| Unlimited | Unlimited | Unlimited | Unlimited | Unlimited | Unlimited |
| | | | | | |
What we like
- Great customer support features
- Solid customer score of 4.4/5
- Potential to scale the system down the line
What we don’t like
- Higher upfront costs than other services
- Poor security features
- Confusing pricing plans
4. Vonage – Best Training Features
- Prices from: $19.99/user/month
With an overall score of 4.4/5, Vonage is one of the best business telephone systems our researchers have reviewed. With excellent sales and customer service features, and solid security tools, all for the monthly price of $19.99 per user per month, Vonage is a great system for teams on a budget. The system ranks high for scalability too, making it easier to grow with your business’s needs.
For businesses looking to get to grips with internet protocol technology for the first time, Vonage’s packages offer live customer training options covering topics like Online Accounts, Features, and Hardware. The software also provides interactive guided and video tutorials to all of its users to make the learning curve as manageable as possible.
Despite Vonage’s strengths, however, it’s unable to beat contenders like Net2Phone and GoTo Connect because the system doesn’t rank as high across all our criteria. For instance, its customer score isn’t very strong and its packages don’t include international calling.
What's new for Vonage?
Enhanced Call Blocking – Vonage released a new, more sophisticated algorithm to identify and block unwanted calls. (March, 2023)
Highlights
- 2.4 million worldwide customers
- Unlimited calls in the U.S. and Canada
Key Features
- Customizable conference groups
- Unlimited team messaging
- Pricing starts from $19.99/user/month
- Per user price decreases based on the number of users
Vonage pricing
Vonage offers three pricing plans: Mobile, Premium, and Advanced. See how they compare below.
| Price | Users | Unlimited calls in US | 24/7 support | Call recording | Call monitoring | ||
|---|---|---|---|---|---|---|---|
| | | | |||||
| Mobile | Premium | Advanced | |||||
| Unlimited | Unlimited | Unlimited | |||||
| | | | |||||
| | | | |||||
| | | | |||||
| Additional cost | Additional cost | Additional cost |

What we like
- #2 for business features
- Great training features
- Strong scalability score
What we don’t like
- Average customer score
- Not as affordable as other solutions
5. RingCentral – Great for Small Businesses
- Prices from: $20/user/month
We’re massive fans of RingCentral at Tech.co. In fact, after analyzing and cataloging the leading VoIP providers, we found that they provide the best VoIP softphone app and one of the best internet phone services on the market, second only to Ooma.
Receiving a 5/5 for help and support and scalability, thanks to onboarding support and a multitude of ways to contact customer service, it’s a great option for small businesses looking for an all-in-one solution that can grow with the needs of their enterprise. However, while RingCentral’s plans are affordable, its start-up costs are a little steeper than rivals like DialPad and Google Voice. With international calls costing a premium too, RingCentral isn’t able to climb any higher than 6th position.
What's new for RingCentral?
Device-as-a-Service (DaaS) – RingCentral released this new purchase option which allows businesses to rent RingCentral desk phones on a monthly basis, rather than buying them outright at a higher price. (February 2023)
Highlights
- Over 2,000,000 customers
- Very easy to set up and scale as necessary
- Top quality security provisions
Key Features
- Auto Attendant, Group Calling, Call Queue functions
- 24/7 live support, onboarding assistance, phoneline & email
- Multi-factor authentication + password rules
- Core plan available from $20/user/month
- We recommend the Advanced plan for $25/user/month
- Ultra plan available from $35/user/month
RingCentral pricing
RingCentral offers four pricing plans: Core, Advanced, and Ultra. Learn about their prices and features below.
| Price | Users | Video conferencing | ||
|---|---|---|---|---|
| | | | ||
| Core | Advanced | Ultra | ||
| 20 lines max. (for more, contact sales) | 20 lines max. (for more, contact sales) | 20 lines max. (for more, contact sales) | ||
| 100 participants | 100 participants | 200 participants |
What we like
- Excellent scalibility
- Advanced business features
- 24/7 customer support
What we don’t like
- Higher start-up costs than some of its rivals
- Internation calls charged extra
- Average customer score of 3.5/5
6. GoTo Connect – Cheapest Scalable Option
- Pricing from: $27/month/user
GoTo Connect is another safe bet for businesses looking for a budget-friendly VoIP solution. Boasting reasonable monthly prices and options to scale further down the line, the system is great for businesses looking to keep installation costs minimal. And with a customer rating of 4.4/5 — beating industry titans like RingCentral and 8×8 — GoTo Connect also appears to be a firm fan favorite.
Our research suggests its security features are top tier, too. Offering multi-factor authentication, end-to-end encryption (E2EE), and user permissions on all its plans, GoTo Connect is far more secure than lots of other VoIP providers of its kind.
However, despite GoTo Connect’s perks, the solution’s features aren’t as competitive as others on the list. For instance, the service lacks basic functions like call transcription, call monitoring, predictive dialing, and custom call lists. Unfortunately, just like Net2Phone, its shortage of standard VoIP features rules the service out from being used by many larger companies.
What's new for GoTo Connect?
GoTo Contact Groups – You can now easily group and organize your contacts into contact groups. You can do this manually or through CSV import. (October 2023)
Instant Message Response – GoTo’s new feature allows you to set up an instant response in its desktop app and customize its time period and response frequency. (August 2023)
Highlights
- Enterprise-grade system
- Established private and public sector clients
- Lots of features for the price point
Key Features
- Integrate with Salesforce, Zoho, Slack & Outlook
- Call conferencing on all plans
- Call queue, ring groups & spam prevention
- Pricing starts at $27/user/month
- Standard plan available for $32/user/month
GoTo Connect pricing
GoTo Connect offers two plans: GoTo Connect Basic and GoTo Connect Standard. Scroll down to learn more.
| Price | Users | Unlimited calls in US | ||
|---|---|---|---|---|
| | | |||
| Basic | Standard | |||
| $29/user/month | $39/user/month | |||
| Unlimited | Unlimited | |||
| | |
What we like
- Great value for money
- Scalable packages that can grow with your business
- High customer score of 4.4/5
- Compatibility with over 180 desk phones
What we don’t like
- Ranked worst for external connection features
- Limited feature set
7. 8×8 – Best for Sales Teams
- Prices from: $24/user/month
Next up, we have 8×8. With our research ranking it #1 for business and security features and its plans starting from as low as $24 per user per month, we think 8×8 is the best VoIP option for sales teams.
Sales features are really what truly sets 8×8 apart from its competition. Through speech analytics software, businesses using the system can gather useful customer insights to improve their sales record. Users can also use 8×8’s unique dialing capabilities and AI virtual assistant to improve their call productivity — tools that are fairly unique to the provider.
8×8’s expansive tool kit aside, the system has only been able to achieve a value score of 2.5/5 because basic features like analytics and call transcription are reserved for users of premium plans. And with 8×8’s higher tiers costing as much as $140 per user per month, the system’s average price is far above most of its rivals. 8×8 does rank well for scalability though, meaning that its value for money is likely to improve over time.
What's new for 8x8?
SMS Spam Blocking – 8×8 has recently introduced a spam prevention feature that lets admins block messages from select numbers for the whole company. (May 2023)
Microsoft Dynamics 365 Integration – 8×8 has also deepened its connection with the CRM platform, allowing users to tailor CX workflow within Dynamics, and benefit from single sign-on options. (May 2023)
Highlights
- 5-star security features
- Unlimited inbound and outbound calls to 48 countries
- Huge number of integrations
- More features than most VoIP providers
Key Features
- Video and call conferencing on all plans
- Live chat + phoneline support 24/7
- Call-flow designer
- Ring groups
- Call queue
- Pricing starts from $24/user/month
- 30-day free trial
- Contact center plans: $85-$140/user/month

What we like
- Sophisticated business features
- Can grow easily with businesses
- #1 for security features
What we don’t like
- Cheaper options are available
- Average customer score
8. Net2Phone – Great for International Use
Pricing from: $23.99/user/month
With Net2Phone’s cheapest plan weighing in at $24.99 per user, per month, the system’s price point may be marginally steeper than its rivals. However, after reviewing the provider’s full package, our researchers have awarded the system a value score of 4.5/5 making it one of the best value VoIP systems on this list, and great value for international businesses in particular.
So what justifies this impressive score? Well, while Net2Phone may not be the cheapest VoIP phone service we reviewed, its entry-level package includes free desk phones and unlimited domestic and international calls to over 40 countries. Since these benefits typically cost VoIP customers a premium – with providers like Google Voice charging as much as $2.50 per minute for calls to certain territories – Net2Phone is much more likely to save businesses money in the long term.
The service isn’t perfect though. Net2Phone ranks poorly on scalability, coming in 7th place after providers like RingCentral, 8×8, and Vonage. This means that while the provider’s system is great value overall, you may be forced to invest in a different solution if your business’s needs diversify down the line.
Net2Phone’s feature set is pretty limited too. While the plans offer basic VoIP functions such as call voicemail, call forwarding, and business SMSs, they forego standard external coms, call management, and conversation features. This makes the system less suited for larger enterprises and those with specific business call requirements.
Highlights
- Scalable from 9 users to over 101
- Superb reporting package
Key Features
- Integrates with Microsoft Office, Google and others
- File sharing
- Voicemail to text
- Call recording
- Plans from $24.99/user/month
- Domestic and international calls included
Net2Phone pricing
Net2Phone offers three packages for small businesses: Office, Pro and Power. See how they compare below.
| Price | Users | Unlimited calls in US | 24/7 support | Call recording | Call monitoring | ||
|---|---|---|---|---|---|---|---|
 | | | |||||
| Office | Office Pro | Office Power | |||||
| $24.99/user/month | $26.99/user/month | $29.99/user/month | |||||
| 5-19 | 5-19 | 5-19 | |||||

What we like
- Affordable pricing plans
- Domestic and international calls to 40+ countries included
- 24/7 support
How Do I Switch VoIP Providers?
If you aren’t happy with your current VoIP provider, it might be sensible to switch to another service that better suits your needs. After you’ve decided which VoIP provider you’d like to move on to, you should notify your current VoIP provider as soon as possible and decide on a service end date. Once your current contract has come to an end, you should be able to get your new VoIP service up and running on the same day you sign up.
However, if you want to stick with your current number, there won’t be any noticeable disruption to your phone service. But we would advise porting your number ahead of time, as the process typically costs extra and takes at least one business day to complete.
We take our impartial research and analysis seriously, so you can have complete confidence that we're giving you the clearest, most useful recommendations.
After conducting an initial exploration to identify the most relevant, popular, and established tools in the market, we put them through their paces with hands-on testing to see their real strengths and weaknesses. In this case, we put ten VoIP systems to the test across 78 areas of investigation.
Based on years of market and user needs research, we've established a VoIP system testing methodology that scores each product in seven main categories of investigation and 16 subcategories; this covers everything from the features and security options available to the product's value for money and customer score, as well as much more.
Our main testing categories for VoIP phone systems are:
Customer Score: the external customer opinion as to their satisfaction with the VoIP product; the feedback and ratings given by customers who have used a particular VoIP system, as well as the market poisiton and reputation a VoIP software holds.
Cost: the pricing structure associated with the VoIP service. It includes factors such as monthly subscription fees, call rates (especially for international calls), setup fees, hardware costs (if applicable), and any additional charges for add-on features or services.
Features: the functionalities and capabilities offered by the VoIP service. This can include basic features such as call forwarding, voicemail, call waiting, and caller ID, as well as advanced features like auto-attendant, conference calling, and call recording.
External Connections: the VoIP service's ability to connect and integrate with external systems or devices. This can include compatibility with existing phone systems, integration with mobile devices, and support for softphones or IP phones.
Customer Support: the assistance and resources provided by the VoIP service provider to customers. This can include technical support, documentation, online resources, knowledge bases, and access to customer support representatives.
Security Options: Security options refer to the measures and features implemented by the VoIP service to ensure the confidentiality, integrity, and protection of voice communications and data. This can include encryption of voice calls, compliance, password ruels and user permissions.
Scalability: the ability of the VoIP service to accommodate the growth and changing needs of an organization. This includes factors such as the capacity to handle a growing number of users, support multiple locations or offices, and scale up or down according to the organisation's requirements.
When it comes to calculating a product's final score, not all testing areas are weighted evenly, as we know some aspects matter more to our readers than others, which are merely "nice to have." After hundreds of hours, our process is complete, and the results should ensure you can find the best solution for your needs.
At Tech.co, we have a number of full time in-house researchers, who re-run this testing process regularly, to ensure our results remain reflective of the present day.
Verdict: Which Cheap VoIP Provider Should You Choose?
Based on entry price alone, our research suggests that Google Voice is currently the cheapest VoIP phone service on the market. Undercutting its runner-up by $5 per user per month, this system is a safe bet for smaller teams looking for no-frills business phone software. If you’re after a budget VoIP service that doesn’t sacrifice quality, 8×8 and DialPad are also great alternatives — with 8×8 ranking #1 for business features and DialPad providing an excellent customer experience.
Even with our guidance, we understand that whittling through the competition isn’t easy. This is why we’ve developed a unique tool that lets businesses compare the prices of VoIP providers with just a couple of clicks. Click on the button below to find a budget-friendly VoIP provider in minutes.
However, free VoIP systems normally offer limited business features and have strict user caps. This means they won’t fit the needs of most businesses.
