What is a PBX?

PBX stands for Private Branch Exchange. It's the system that manages your business phone calls — the technology sitting behind the scenes that routes calls to the right person, plays your hold music, handles your after-hours greeting, and connects your extensions together.

Before the internet era, a PBX was a physical box — often a large cabinet — installed in a dedicated room at your office. Every phone line plugged into it. Every call passed through it. If it broke down, your phones stopped working.

Most Australian businesses that set up their phone systems more than ten years ago still have some version of this hardware on-site — and many are now discovering that it's become difficult or expensive to maintain.

What does "hosted" mean?

A hosted PBX moves that cabinet off your premises and into the cloud. Instead of a box in your server room, your phone system runs on servers in a data centre — in CallPath's case, on Cloud365's infrastructure in Sydney and Melbourne.

Your phones (or softphone apps) connect to it over the internet. From a user's point of view, everything works the same way — but there's no hardware at your office to maintain, repair or replace.

The short version: a hosted PBX is your business phone system running in the cloud instead of on a box in your office — with all the same features, none of the hardware.

How does it actually work?

When someone calls your business number, the call travels over the phone network to your hosted PBX in the cloud. The PBX applies whatever rules you've set — plays your greeting, routes the call to the right team or person, puts the caller in a queue if no-one is available, or sends it to voicemail after hours.

Your staff answer calls using either:

  • A softphone app on their computer or smartphone
  • A physical SIP-compatible desk phone connected over your internet connection
  • A mobile or landline number you've set up as a divert

Because everything runs in the cloud, it doesn't matter where your staff are located. A team member working from home answers on the same extension as someone in the office.

What features does a hosted PBX include?

A well-configured hosted PBX gives you the full range of features you'd expect from a professional phone system:

  • Auto attendant and IVR menus ("Press 1 for sales, press 2 for accounts")
  • Call queues with hold music and overflow routing
  • Hunt groups that ring multiple staff simultaneously
  • Voicemail delivered to your email inbox as an audio file
  • Call recording for compliance or training
  • Time-based routing for after-hours and public holidays
  • Direct inward dial numbers for individual staff or departments
  • Conference calling

Hosted PBX vs managed hosted PBX — what's the difference?

Not all hosted PBX services are the same. Many providers give you a hosted platform and a login, then leave you to configure it yourself. You're responsible for setting up your menus, adding extensions, managing routing rules, and troubleshooting problems.

A managed hosted PBX — like CallPath — is different. We design, configure, and maintain the entire system on your behalf. When you need something changed, you contact us and we handle it. You never need to log in to a technical dashboard or understand how the system works internally.

For most small and medium Australian businesses, the managed approach makes more sense — particularly if you don't have dedicated IT staff.

Is a hosted PBX right for your business?

A hosted PBX is worth considering if:

  • Your current phone system is ageing or becoming difficult to maintain
  • You have remote workers or staff across multiple locations
  • You want a professional call handling experience without hiring a receptionist
  • You'd prefer a predictable monthly cost over periodic hardware investments
  • You want a phone system that can grow with your business without expensive upgrades
