What is a PBX Phone System?

PBX stands for Private Branch Exchange, which is a private telephone network that's used within a company. Traditionally, companies utilizing a PBX system would have specific proprietary phones for the software. Nowadays, however, most companies use Open-Standards-based IP-PBX, which allows the companies to use the IP in VoIP as the transport technology. Besides saving your company money, a PBX phone system bypasses many of the traditional phone system delays, such as

  • Ring groups
  • Queues
  • Voicemail, and more

A Private Automatic Branch Exchange is slightly different than a traditional PBX system in that calls and exchanges are taken care of automatically, as opposed to via a live operator. Most systems nowadays are in fact PABX systems even if only referred to as PBX. It's important to understand all of the details associated with PABX systems in order to make the most of it in your company.

Benefits of PBX for Business

As your company grows you’ll need to scale your VoIP system as well—and a PBX system is the best way to link all of the phones in your company together, even across multiple locations.

Here are some of the benefits to incorporating PBX in your business:

  • Central control - The receptionist feature allows external callers to access your company through 1 phone number and PBX technology allows multiple callers at once.
  • Simple internal communication - When you call another employee at the office through a PBX the call is rerouted internally and doesn’t go outside the building like traditional phone systems which incur a charge.
  • Useful features - For example: Auto attendant, which replaces a traditional receptionist and cuts out wait time for callers, and call routing/follow-me, which enables you to forward calls from your office phone to any other phone in the exchange system.
  • Maintenance-free system - Since a PBX uses the internet for calls, you save money on equipment—which means less maintenance than traditional phones and lines.

Hosted PBX Vs. On-Premise PBX

Hosted PBX is where the provider hosts the PBX and handles the technology that provides the service, while on-premises PBX is, as you’ve probably guessed, where the technology is stored on the premises of the company. The IP routing of on-premise PBX may use more current technology than hosted PBX.

Here are some of the main differences between hosted and on-premise PBX:

Hosted PBXOn-Premise PBX
  • Cheaper to set-up
  • Customer pays for upgrades
  • Programming managed by customer
  • Customer responsible for staff training
  • Low monthly cost
  • Easy to add lines
  • Upgrades/new features included
  • Higher setup cost
  • Higher maintenance costs
  • Lower monthly costs
  • Provider qualifies network
  • Provider installs and programs PBX
  • Provider trains staff

How to Choose

When deciding between a hosted PBX and an on-premise PBX, the question basically comes down to your company’s size and IT capabilities and needs:

 Hosted PBXOn-Premise PBX
Recommended For 
  • Small businesses that want to save money
  • Businesses that don’t have in-house IT resources
  • Medium- to large-sized companies with IT capabilities
  • Companies that want control over their phone system
  • Companies that need a customized solution

Here’s a breakdown of the choices. If your company is small and needs to stay conservative with money, and also doesn’t have the proper in-house IT capabilities, it’s probably better that you start out with a hosted PBX system. If, however, your company has in-house IT capabilities that can handle its own phone system’s needs, then the on-premise PBX is the way to go.

For small and medium-sized businesses, Vonage has developed Vonage Business Cloud, in addition to its larger enterprise options.

This VoIP giant offers more than 40 features for professional calling convenience and ease, yet Vonage caters its plans to suit your business size. So, you can opt for the more basic Essentials plan that offers Amazon Chime Pro, month-to-month contracts, and dedicated mobile and desktop apps, or go for the gold with enterprise level plans that up the game with things like hunt group, auto attendant, and visual voicemail.

With the state-of-the-art Chime feature, you can host online meetings and enjoy quality VoIP calling and even video conferencing for up-to-the-minute team collaboration.

Depending on your preference, Vonage Business can connect directly with your desktop, or you can choose the softphone option that connects your phone line to your computer.

Users can also sign up for the Enterprise SMS solution, VideoConnect and CRMConnect, which seamlessly connects with your existing CRM software.

8x8 Logo

  • Easy-to-customize platform
  • Great call quality
  • Competitive pricing plans

8x8 Global Cloud Communications is a relatively smaller VoIP provider for businesses, but it is one of the top picks by industry experts, and it has enterprise-level services. It's got a great features suite, reliable connections, and a whole slew of third-party integrations, so you are getting a ton from the already attractive 8x8 pricing plans.

To start with, 8x8 can be used with a standard Polycom handset or through your PC (Mac or Windows) or mobile phone (iOS or Android). Once signed up, 8x8 will schedule a meeting to walk you through all of the various features and show you some of what you can do with your new 8x8 service. That is super helpful.

Setup is fast and easy. Plus, 8x8 integrates with the usual software like Sugar CRM and Salesforce. The amount of features available for both mobile and desktop systems is impressive. Some of the features we were happy to see for mobile included:

  • Receiving calls and making them
  • Voicemail
  • Receiving faxes
  • 3-way calling
  • Call recording
  • Define presence

And, a lot more. And that’s just what you get for mobile. The desktop functionality is even more robust with things like conference calling bridge, video calling, and team collaboration features, to name a few.
