Upgrade Your PBX System

What Is a PBX Provider?

A private branch exchange (PBX) system is a phone system with business-level features like call conferencing, extensions, greetings, waiting queues for callers, and much more.

More specifically:

Cloud-hosted PBX providers offer VoIP (Voice over Internet Protocol) phone systems through remote Internet servers instead of requiring expensive hardware to be installed in your office, unlike traditional phone systems.

This virtual phone system is secure, convenient and reliable, making it a great choice for businesses. And since no physical hardware is needed, it’s easier to scale by adding new extensions and business lines quickly, which is especially helpful for remote workers.

If you’ve made the decision to switch to a cloud PBX provider (or you’re weighing your options!), this roundup will take you through the top six hosted PBX providers to help you find the right choice for you.

Why Use a Cloud PBX System?

Companies that have multiple phone lines for different employees and departments need a phone system, but if they wind up moving locations or even adding a single line, it could be time-consuming and expensive because physical hardware is involved.

There are a number of reasons why businesses are choosing cloud PBX systems, such as:

  • They’re cost-effective. You’re only paying for the phone lines and features that you’re actually using, so you’re never overpaying. They also cost less than traditional in-office options, which require expensive hardware.
  • They’re easily scalable. It’s quick and easy to add an extra line with just a few clicks.
  • There’s a limited need for hardware and new equipment. Most options even allow you to download mobile apps to existing devices so you don’t even need to supply your staff with their own phones.
  • They have enterprise-grade security. Cloud-based solutions are highly secure, using top-of-the-line security and encryption technology to protect your information (and your customers’!).
  • Reliable uptimes. Most PBX providers, as you’ll see in the next section (“The 6 Best Cloud PBX Providers”), have exceptional uptimes that hover around 99.999%. This is outstanding and provides the ultimate reliability for your business.
  • Robust integrations with existing systems. The fact that these business phone systems are digital is such a big advantage when it comes to integration with other SaaS tools. While integrations vary depending on the tool, almost all offer some.
  • Seamless software updates and upgrades. Most technology develops rapidly and business phone systems are no different. You want a system that’s able to receive frequent updates, and with a PBX business phone system, updates will happen automatically instead of needing someone to come update the hardware in-office.
  • Access via desk phones or soft phones for maximum flexibility. If you want your team to have phones at their desk, there’s nothing stopping you from doing so with a PBX system. That being said, these same users can also access the lines (and their voicemail) from the remote app on their mobile phone. The flexibility and ability to move to remote access is phenomenal.
  • No long-term contracts or lock-ins. Almost all PBX systems (and certainly all the ones we’ve reviewed here) do not have any contracts or locked-in costs. You’re paying for what you need when you need it, and you can scale up or down or even cancel at any time.

The 6 Best Cloud PBX Providers

Now that you’ve learned how flexible these phone systems are, let’s move on to reviewing the top PBX providers that we recommend for businesses of all sizes.

1) Nextiva

Nextiva is our top choice for PBX providers, partially because they offer high-quality commercial services that integrate with their customer relationship and internal teamwork solutions.

Nextiva’s virtual phone system allows users to access a business line on their personal cell phone. This is extraordinarily convenient, as it reduces the need for additional devices:

How to Choose the Right Cloud-Hosted PBX Provider  

Now that you’ve learned the benefits of using a cloud-hosted PBX provider and have read through the top choices that we recommend, you’re ready to choose a hosted PBX provider for your business.

There are six great options that we’ve detailed here, and plenty more that we haven’t. So how do you choose which provider is right for your business?

To help with this, we’ve put together a checklist that you can use to compare providers to see who best aligns with your needs. Go step by step through the list to make sure that a provider has what you need before you get started:

✔️ Do they meet your phone system requirements?

This is a simple question, but it’s an important one. Do they have the security that you need and all the features that you’re looking for? For instance, maybe texting is particularly important to you. This isn’t something that all providers offer, so you’ll need to double check this before proceeding even with a trial.

✔️ What does implementation and onboarding look like?

How difficult is it to get started? Is there a waiting period or is it as simple as picking a number (or porting your current business line) and getting things set up?

✔️ Will I need dedicated customer support or sales engineers for help?

Is the system and interface complicated enough that you’ll require ongoing support every time you need to make a change, like adding a new line or upgrading to get new features? The less hassle, the better.

✔️ Can they offer the office phone system features you need?

It’s not just about what you need right now, it’s about what you’ll need long-term, too. Maybe, for example, you don’t need an auto attendant because you’re a small business with a receptionist, but in the long-term you probably will if your business continues to grow.

✔️ Are they able to support your remote workforce?

One of the biggest benefits to a cloud PBX system is that they should be able to facilitate remote work in a way that traditional VoIP systems don’t. Even if you aren’t planning on having most of your team work from home, we all know there are incredible benefits to having that flexibility. Just in case, I don’t know, an unforeseen event like a global pandemic occurs….

✔️ How do they hold up on review websites?

Take a look at any of the services you’re considering on third-party review sites, as well as reviews on platforms like Google My Business. You can get a good feel for how happy other customers are on an ongoing basis, including with their customer support.

✔️ Do they have similar-sized customers as your business?

If you’re an enterprise-grade client with 200 employees, you’ll want to find a cloud PBX phone system that doesn’t just work with small businesses with three employees. This will help you feel confident that they have the internal infrastructure needed to support businesses of your size and needs.

✔️ Do they offer unified communication?

Unified communications are a little like omnichannel marketing. You want your entire communication system to be streamlined, so your PBX system should ideally offer more than just a phone plan for calls. Think texting, email integration, and more.

✔️ What usage costs and taxes does the quote or pricing include?

This is an important factor, because some PBX providers and other business phone systems will bury extra costs and taxes in the fine print. It may say that you’re paying $25 a month for the service, but then you end up with $20 in taxes. Ask the sales rep carefully to ensure that you know exactly what you’ll be paying and what it covers.

✔️ How do they ensure business continuity?

The last thing you need is a phone system that’s unreliable and dropping out regularly, as it can be not only embarrassing and frustrating, but it could cost you customers. Make sure they have a plan and technology in place to guarantee high levels of uptime, and a plan for what to do if that uptime fails.

✔️ Can they integrate with my existing software?

Some businesses won’t care about integrations, but for scalability and ease of use, PBX cloud providers that come with integrations available can be a huge asset. It streamlines different processes and provides your team with more resources. See if the provider you’re considering offers integrations with tools you’re already using. If not, see if another provider does.

✔️ Do they offer call analytics?

Call analytics is an exceptional benefit of PBX hosted services, giving you information like which departments are receiving the most calls and which reps are staying on the phone the longest. Platforms that offer call surveys to customers can also compile that data here. See what call analytics the provider has to offer before signing up.
