What is hosted PBX?

Hosted PBX or Hosted VoIP, also known as a Virtual PBX, is an Internet phone system or private branch exchange (the private telephone network used within a company to make and receive phone calls outside of the business) delivered as a hosted service.

This means that the provider is responsible for housing the IP-PBX (Internet Protocol Private Branch Exchange), as well as maintaining and managing the technology required to provide the services to the phone system.


Cost-effective and scalable hosted PBX phone systems (IP PBX) delivering flexibility and reliability.

How it works:

At the user level, an employee’s IP desk phone connects to a router where the calls, signalling and features all run through an IP-PBX server based at the service provider’s location. A monthly fee is typically paid for this service, with businesses having the ability to add and remove features as and when they are needed, which provides a significant degree of flexibility.

  • A significant reduction in installation, operation and maintenance costs
  • No training or specialty knowledge required for running the phone system or adding extensions etc., as the PBX provider maintains the system
  • Scalable with your business
  • Superior integration – including CRM integration
  • Simple addition of extra lines
  • Low monthly service cost
  • Outsourced maintenance
  • Extended features, like conferencing (may come with additional costs)
  • Highly flexible – this includes month-to-month payments to avoid lock in, as well as being able to transfer office extensions to mobile
  • Potential to reduce telephone costs by up to 80% by leveraging SIP trunks, WebRTC, free calling to remote extensions and reducing the number of telephony lines
  • Superior call quality when paired with the right internet connection
