Understanding Modern Business Phone Systems
Businesses evaluating modern phone systems often encounter two common terms:
- Hosted PBX
- Cloud PBX
At first glance these terms may seem interchangeable, and in many cases they are used to describe similar technologies.
However, there are subtle differences in how these systems are deployed and managed.
Understanding these differences helps businesses choose the communication platform that best supports their operations.
In this guide we explain:
- What Hosted PBX systems are
- What Cloud PBX systems are
- The differences between them
- Which solution is best for modern businesses
If you're new to business telephony, first read: What Is a Cloud PBX Phone System?
What Is a Hosted PBX?
A Hosted PBX is a business phone system that is operated by a service provider and hosted in a data centre.
Instead of installing PBX hardware at your office, the provider manages the system remotely.
Businesses connect to the PBX platform through the internet using:
- IP desk phones
- Softphones
- Mobile applications
The provider is responsible for maintaining the infrastructure, updates, and security.
Hosted PBX systems became popular as an alternative to traditional PBX systems because they eliminated the need for expensive telephony hardware.
What Is a Cloud PBX?
A Cloud PBX is a more modern evolution of hosted telephony systems.
Cloud PBX platforms are built using scalable cloud infrastructure that allows the system to expand dynamically based on demand.
This means the platform can easily support:
- Growing businesses
- Remote teams
- Multiple office locations
- Call centre operations
Cloud PBX platforms are typically designed with greater flexibility and integration capabilities.
