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.

 

Take a Look at the Leading VoIP Systems for PBX:

Vonage Logo

  • Top notch voice quality
  • Seamless desktop-to-mobile cross over
  • Professional admin features

Vonage is a pioneer in the VoIP industry, and now it’s making waves with its business products as well. In addition to the standard Voice over IP, Vonage Business also supports newer protocols like Multiprotocol label switching and software-defined wide area networks for the most advanced and extensive business telephony services available today.

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

The platform is easy to set up and fully scalable so it can work for small businesses that are on their way up and medium-sized businesses who already have more extensive VoIP needs.

With every Vonage Business Cloud plan you get 99.999% uptime, additional bandwidth, mobile and desktop apps and unlimited calling and text messages.

Business Cloud plans range from the entry-level Mobile plan at $19.99/month and up, through the Premium and Advanced plans ($29.99 and $39.99 per month, respectively).

Going to premium is a good decision if you need video conferencing, chat and file sharing as well as more extensive integrations and customer relations management tools, such as Salesforce, Microsoft Dynamics, and G Suite. If you continue on to the Advanced plan, you can also enjoy additional features like visual voicemail, call recording, and call group to name a few.

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.

The cloud interface syncs the information in your business software with detailed inbound and outbound data. So, teams working with the cloud platform can enjoy screen pops for incoming and outgoing calls, click-to-dial service, call history and logging, note taking, integrated reporting, and continuity across cell phones (Apple and Android). 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. Use your pre-existing phones or purchase any of the most popular VoIP phones like Cisco, Polycom, and Panasonic. The choice is yours. Users can also sign up for the Enterprise SMS solution, VideoConnect and CRMConnect, which seamlessly connects with your existing CRM software.

To top it all off, there are 44 standard, non-chargeable extras in all packages, ranging from call blocking and call recording, to virtual receptionists, mobile apps and the Vonage service portal.

8x8 Logo

  • Easy-to-customize platform

  • 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.
