When it comes to evaluating PBX providers, there’s a lot to consider. 

From services to costs to implementation, finding the right PBX providers for your business can be difficult and require a time and resource commitment that could negatively draw from other business processes.

Since businesses are always on the lookout for cost savings, going with the right PBX provider can have a significant impact on your bottom line: a small business with 1-20 employees can expect to pay $16,867 a year for hosted PBX or in upfront licensing fees for an on-premise solution. But for larger companies, that cost can quickly balloon to $1 million. This is where a professional PBX reseller can be a massive help.

When determining the appropriate PBX provider for your business, consider:

In that spirit, let’s evaluate some of the top business phone system vendors, providing a quick overview of their hosted PBX services (as well as VoIP services) so you can better determine which is the right one for your business.

Best PBX Providers in 2021

Ring Central 

RingCentral Cloud PBX offers, among other services: 

  • Conference calling
  • Call routing
  • Text messaging services
  • Video conferencing services

Its business suite platform, RingCentral Professional also can integrate with many other commonly used business services like Outlook, Salesforce, Google Docs, and DropBox, making it an ideal solution for businesses that rely heavily on the above platforms. 

RingCentral Cloud PBX systems pricing ranges from $25.99 per user/per month for Pro Plus to $49.99 per user/per month for Office Standard. Note that the Pro plan does not offer technical support by phone. The Office Standard, by contrast, does grant access to unified communication tools and technical support.


The two main features of 8×8 that set it apart among PBX providers are its intuitive design and its friendly price point. 

Starting at $12 per user/per month, you’re not getting a budget PBX system by any means. In fact, it’s safe to say that 8×8 plans are among the best deals in the industry, bundling attractive prices with a host of strong features, including:

  • Auto-attendant services
  • Intelligent call routing
  • Voice, video, and messaging through one app

Combine this with a very intuitive user interface and gentle learning curve, and you have a great PBX provider. What’s more, it offers a variety of packages, so you can quickly scale up or down depending on your business’s needs.


Vonage offers many features to users – perhaps more than most PBX providers. 

The one thing that your business will need to be wary of is the price: the per user/per month costs of Vonage can run up quickly depending on the specific feature added. 

The entry level package comes with basic communication features and is priced at $19.99. The next tier up adds CRM integration and a multi-level auto attendant for $29.99, while the Advanced tier includes call recording, visual voicemail, call groups, and full support for initial setup, but it runs $39.99 per use/per month.

As far as mobile apps go for PBX providers, Vonage has one of the handier ones, offering easy call note-taking and other benefits. 

Best PBX Providers


Dialpad is keenly focused on innovation and integration. It has one of the most compatible services, with the ability to integrate a variety of apps into its service. 

It also features some of the strongest AI-driven tools for small businesses, something that will often cost your business much more when looking at other providers. 

The tradeoff is that Dialpad lags behind in metric delivery for calls, but more than makes up for that deficiency by providing sales-focused tools for businesses. 

At $20 per user/per month ($15 if paid annually), Dialpad can be a cost effective solution for those looking to boost their sales experience while potentially losing out on more in-depth KPI metrics that other PBX providers offer. The Pro level includes 24/7 support and Salesforce integration for $30 ($25 if paid annually).

Another key feature of Dialpad is a 14-day free trial so you can test out the service before committing. 


Being among the larger companies on this list, you get all the benefits that multinational, multibillion corporations provide – alongside all the drawbacks. 

You can get VoIP and PBX services for larger institutions or smaller businesses, but you will have to pay a bit more for services you’d get from other providers at a discount. 

The positives of going with Verizon is that the company has a lot of interoperability as well as a wide variety of supplementary services you can add on to your system. 

What’s more, Verizon can integrate with your existing phone systems or you can acquire a whole new set from the company. 

You’ll be looking at $25 per user/per month for 20-plus VoIP lines. 


The ubiquitous online call service also offers a comprehensive business phone plan for cloud-based PBX. 

Working with Zoom allows you to access a good number of features, alongside top-tier customer support and call recording. It also has a dedicated mobile app that’s one of the best. 

And with Zoom becoming so popular in the last year, it’s been flooded with a wealth of resources and capital that will likely help it continue to grow and improve moving forward.

You also get to work with a company that’s well-known and has a strong reputation.

Zoom only offers annual prices, running at $120 per user for its introductory plan. Prices range upwards to $300 per user for the most comprehensive plan. 

Comcast Business 

Another heavy hitter, Comcast offers a strong list of starting features for their basic plan, including: 

  • Multi-Site Use
  • Call Forwarding/Remote Call Forwarding
  • Call Waiting
  • Call Hold and Transfer
  • Call Park/Call Pickup
  • Distinctive Ring
  • Auto-Rerouting
  • Be Anywhere
  • Sim/Sequential Ring
  • Outbound Caller ID Display via Mobile Phone
  • Mobile Notification for Calls and Voicemail
  • Business Voicemail on Mobile Phone
  • Voicemail/Readable Voicemail
  • And more

With more expansive packages, you’ll have more mobility options and accessibility to these features even when you’re on mobile. 

You’ll also benefit from an online account management tool, granting your business a number of system administration services, and also makes it easier to add or drop features on your phones. 

As a cloud-hosted PBX service, you’ll get guaranteed reliability as calls are routed through Comcast’s extensive network. 

While you can see what each level of service offers on the website, you’ll have to contact them to get a quote for their services, or work through a procurement specialist. 

ACC Telecom

ACC Telecom business PBX offers everything you should expect from a PBX solution, including:

  • Online management
  • Call recording
  • Voicemail to email & text
  • Mobile apps
  • Video teleconferencing
  • Chat
  • Contact center software

  • And more

They also offer four distinct packages/levels of services:

  • Cloud phone system
  • VoIP PBX Software
  • VoIP on-premise server
  • Digital phone system

Finding the right one for your business depends on size, services and features you’re looking for, whether you want the privacy of on-premise solutions or the scalability of cloud, etc. 

ACC Telecom offers varying price levels for the above services, with a cloud phone system (virtual/hosted PBX), you’ll end up paying $16.99 per user/per month for a company of 20-100 employees. 

For the next tier up and it’s additional services, you’d have to contact the company directly or work through a trusted third party procurement specialist like OnCall Telecom.
