Compare Top Virtual PBX Services

ChooseWhat's virtual PBX comparison gives people searching for a business phone system all of the information they need to make a quick, easy decision on a virtual PBX system.

What is a Virtual PBX?

A virtual PBX is a business phone system that is hosted by a service provider and includes a virtual number (i.e. a number that is not connected to an associated land line) and an online account dashboard, which gives you access to call logs, messages and system settings.

With a virtual PBX, you have all of the functionality of a traditional business phone system without any hassle or exorbitant expenses.  Your virtual phone line is hosted online and maintained by your service provider, which makes system maintenance a non-issue.

How Does a Virtual PBX Work?

How Does Virtual PBX Work

Virtual PBX systems work by using the Internet and a virtual number to create a phone system that gives your business a professional appearance as well as key phone features, such as call routing, call forwarding and conference calling. 

The diagram above depicts how a typical virtual PBX can handle incoming calls: 

  1. A phone or fax machine dials your virtual number. 
  2. An auto attendant will direct the caller to the appropriate department or person. 
  3. The call can be fowarded to several remote numbers, including your smartphone, your home phone, direct extension or computer.    

Who Should Use a Virtual PBX? 

Anyone who doesn’t want to invest a lot of money on a traditional PBX system but still needs business phone system features should use a virtual PBX.  

Because virtual phone numbers can be easily set up to forward to another existing phone line, they are convenient for the following types of users:

  • Start-Ups or Small Businesses that want to seem bigger/more professional
  • Technology Companies offering technical phone support
  • Exporters or Virtual Offices who want to give the impression that they are local
  • Service Companies, such as call centers
  • Companies with Multiple Employees/Agents out in the field who want to be reached through one number
  • Mobile Users who don’t want to give out their personal mobile numbers
