As one of the more popular names in VoIP, Ooma, is a cloud-based VoIP solution that caters to small businesses that specialize in an array of industries. Ooma not only helps businesses manage their operations and become more efficient but also helps them become more professional.

First, what is VoIP? Voice over Internet Protocol (VoIP) is a groundbreaking technology that allows users to make telephone calls through the internet instead of relying on a separate phone line. Even if you’ve never heard of it, chances are you’ve used it.

After conducting thorough research and reading customer reviews, we’ve found that Ooma Office's business VoIP is best for small businesses on a budget.

Ooma business VoIP benefits

Ooma claims to gear its services around small businesses. Its proprietary, high-definition voice quality system doesn’t have the features some of its larger competitors do. However, it provides an affordable price tag and easy-to-use interface. As an award-winning Voice over Internet Protocol system, Ooma garners thousands of customer reviews on Amazon with an average rating of 3.9 stars.

Ooma offers a comprehensive VoIP plan for businesses for only $19.95 per month per user, as well as an upgraded version of that plan for $24.95 per month per user.

Ooma’s pros and cons


First, we’ll start with the positive features. Ooma has a lot going for it. Here are some of the advantages of Ooma.

  • Scalable: Ooma breaks the mold of the traditional VoIP solution by offering scalable solutions for startups and small businesses. In a small business, it’s important to pay only for the features and users you want. As your business grows, you can add more users and features.
  • Affordable costs: Ooma’s business phone service offers a decent number of features for only $19.95 per user per month.
  • Live chat: Running a business can be a difficult task. With Ooma Office, users can benefit from 24/7 live chat. Plus, Ooma’s reviews claim that its representatives were not only helpful and friendly but also educational and informational. According to the reviews we read, you can expect quick follow-ups.
  • Online knowledge base: If you can’t reach its customer service hotline, dig into the online knowledge base. Ooma offers a slew of video tutorials, FAQs, and troubleshooting.
  • Wireless phones: Through Ooma Linx, businesses can place wireless phones in multiple locations for employees.


Like all services and products, Ooma has a few drawbacks. If you’re thinking about investing in Ooma, also consider the following disadvantages.

  • Hardware costs: Many VoIP competitors include built-in costs, but a significant downside to Ooma is its one-time hardware costs.
  • Customer service: We mentioned that Ooma handles 24/7 customer chat like a pro. But it also offers customer support over the phone as well. If you prefer talking to a person on the phone over online chat, call its customer service phone number at 888-711-6662.
  • Complaints of dropped calls: As we conducted our research, we noticed some mixed reviews. For example, there were reports of call drops and downtimes, so keep that in mind during your search for VoIP plans.
Get your business connected

RingCentral is our top VoIP choice for small businesses because of its unlimited domestic business phone and messaging, starting at just $19.99/mo.

  • Adaptable to your business needs from equipment rentals to toll-free numbers
  • Global infrastructure with an easy setup
  • Easy to scale and find a plan that works for you—regardless of your business’s size

VoIP terms to know


Ooma Office is a full-featured, virtual PBX (Private Branch Exchange). This means it can assist several devices and extensions at an affordable cost.

SIP trunk

As a Session Initiation Protocol (SIP), this technology transfers voice, data, and video through a data network of copper telephone connections through the Public Switched Telephone Network (PTSN). This connects phone and internet service to an individual digital line.

Number porting

If you are considering upgrading or switching your phone service, it’s important to keep number porting in mind. Luckily, unless your business is dramatically changing geographic locations, most VoIP services offer number porting. With Ooma, business owners can easily transfer their existing number over.


This concept is similar to bring your own beer, only more techy. Bring your own device (BYOD) refers to the policy of allowing employees to bring their personal laptops, tablets, and phones to the workplace instead of working on company equipment. Although most VoIP companies offer BYOD, Ooma doesn't support BYOD at this time. For further information, check out our guide to BYOD.

What are the benefits of VoIP?

VoIP offers a slew of advantages for businesses. Regardless of the type of your business, here are the benefits of VoIP:

  • Installs and configures easily
  • Scales with your businesses
  • Supports older technology (like fax)
  • Saves businesses money in the long run
  • Integrates with other software

Still unsure how VoIP benefits businesses? Here’s an in-depth look at Voice over Internet Protocol and its advantages.

What are some features of business IP phone services?

  • Financial security: A VoIP telephone system offers a lower up-front cost for small businesses in a variety of ways.
  • Flexibility: VoIP phone systems offer businesses a flexible way to communicate. When investing in VoIP systems, business owners can scale up or down their usage or number of seats depending on the size of their company. More and more phone systems, including Ooma, are offering businesses affordable and customized plans to meet the goals of a modern business.
  • Portability: VoIP doesn't have to be secluded to an office space. Ooma’s business plan allows users to make and receive calls as if they were in the office.
  • Multifunctional setup: Another big advantage of Ooma VoIP we haven’t mentioned is its multifunctional ability. In addition to providing phone systems for businesses, it also provides smart home security for homeowners. Residential users get unlimited nationwide calling, real-time alerts, automatic alarming and disarming, and easy wireless installation. Plus, in the unfortunate event that you need to call 911, your home address automatically transmits to emergency responders.

Why should my business consider a VoIP phone service?

If your company is using an archaic telephone service, a VoIP system can replace it seamlessly and easily. VoIP can also connect directly to your business’s PBX (Private Branch Exchange), which eliminates the need for a separate line.

What are some alternatives to Ooma?

Although Ooma is a leading VoIP provider for small businesses, you may want to keep browsing due to your unique preferences. Other VoIP business phone systems we recommend include RingCentral, Nextiva, Grasshopper, and Vonage.

What are the common VoIP pricing and costs?

In our research for the best business VoIP providers, we’ve found that most plans start at $20 per user per month and increase to $55 per user per month. Keep in mind that pricier plans offer more advanced, feature-packed plans.
