Naturally, the cloud-based system requires a good internet connection in order for it to work. But a great thing about RingCentral is how well it integrates with existing PBX hardware. Thanks to the high-quality technology used, the sound quality during voice calls is always crystal clear. The company also offers HD video and audio conferencing features as well as HD screen sharing. 

A few other features worth mentioning include call logging, monitoring, and recording. The service also enables you to send and receive faxes online.

Aside from offering the usual software and hardware resources that go hand in hand with any phone system, Dialpad also helps sales and marketing teams navigate the modern information marketplace.

Dialpad uses artificial intelligence to augment the calling experience. It does this by offering live prompts to helpful resources whenever a caller asks a question. It also helps sales and marketing representatives answer customer questions by providing access to much-needed information in real time. Moreover, each conversation is recorded and transcribed using AI so that you can focus on the conversation rather than on taking notes. These transcriptions can also be fed directly into CRM software like Hubspot or Salesforce.

All plans come with unlimited calls and messaging. Custom voicemail, auto-attendants, contact syncing, and hold queues are just some of the other features on offer. Dialpad also lets users access its video-calling tool, Uberconference, to host conference calls of up to 10 participants for 45 minutes.

Best for small businesses

Ooma Office website screenshot

The ideal VoIP solution for traditional small businesses


Pricing: From $19.99 per user/mo
Features: Mobile app, ring groups, video conferencing (Pro plan-only)
Support: Live chat, knowledge base, 24/7 phone

Reasons to buy

Affordable rates
Excellent hardware
Unlimited local calling

Reasons to avoid

Not many extra features

Founded in 2003, Ooma Office has quickly grown to become a premier name in the business phone system space. It’s currently based in Silicon Valley, California. Ooma’s biggest asset is the excellent quality hardware it offers alongside its products. If you are a traditional business with physical office space, Ooma can supply you with desk phones to meet any communication requirements. 

Ooma Office is a great solution for smaller businesses with a tight budget that are dipping their toes into VoIP territory for the first time. It doesn’t have the bells and whistles that some of the other providers on this list offer, but Ooma’s simple yet efficient system allows you to transition smoothly from your existing PBX setup with no headaches and at a low cost. 

To its credit, Ooma Office isn’t an entirely hardware-based system. In fact, it offers excellent cloud-based services through its functional and intuitive app, which can turn any desktop or mobile device into a “softphone.” This allows you to migrate to Ooma’s environment without investing in any of its hardware, although that isn’t usually recommended. After all, the hardware is this provider’s greatest selling point. 

Ooma charges all users a flat rate per user per month. The costlier plan comes with extra features such as video conferencing, call recording, and downloadable software for your desktop. However, this does not include hardware costs. Any desk phones or other physical products need to be purchased separately for an affordable one-time fee. Each monthly subscription plan gets you free unlimited calling, a virtual receptionist, cheap international calling, and a toll-free number.

The best provider for small teams and solo entrepreneurs

Reasons to buy

Great for freelancers
No call limits

Reasons to avoid

No available hardware
Limited number of users

Grasshopper is a virtual phone service that offers a great solution for solo entrepreneurs and small businesses with their own hardware. If you don’t have the requirement or bandwidth to invest in a traditional VoIP system—which comes with its own associated hardware such as desk and mobile phones—Grasshopper is the perfect solution for you.

The service is especially popular among small-scale, fully remote businesses that have almost all of their staff working from home. By simply downloading the Grasshopper app on your laptop or smartphone, you will be able to use your device as a softphone and access features like business texting, call forwarding, automatic voicemail, and more.

Despite not offering its own hardware, Grasshopper comes with enough features to match any other VoIP service provider. It offers toll-free, vanity, and local numbers as well as essential tools like business texting, online faxing, custom voicemail, video conferencing, and more. These features are available across all plans and come in handy, even if you are a team of one. There are no limits on the number of calls you can make or receive, and 24/7 customer support is available.

Which type of small business phone system is best for you?

When deciding which of the best small business phone systems to use, first consider what actual needs you have. For example, someone simply wanting to talk to a handful of people on a casual basis may find a cheaper option is the most cost-effective while providing all of the necessary tools that would be required. However, if you're planning to use a VoIP provider for professional or business purposes, especially with a large number of people and on a regular basis, then you will probably want to look to the higher-end options for the more advanced tools that are included.
