Phone System Hosting

As remote and blended workforces grow more common, a workplace that supports working from home can provide significant benefits to an organization's productivity, communication, employee well-being, cooperation, and profitability.

This is where Unified Communications solutions such as 3CX come in.

In contrast to traditional telephone systems, which are installed on-site, our hosted system is provisioned and managed from a secure Australian data centre that is accessible through the internet. In terms of functionality, the system outperforms on-premises phone systems, providing benefits that were difficult and costly to achieve in the past. SIP trunks are used to replace phone lines. IP phones have taken the role of specialised handsets. It truly is a replacement technology.

We provide this in two flavours: dedicated and shared.


We offer 3CX as a dedicated hosting package hosted in an Australian data center. This gives you the greatest connection to your hosted PBX system, with minimal latency and excellent dependability.

We can tailor your setup to your specific needs, whether they are single or multi-site, remote and mobile workers, soho, or call centre. There is a web-based Management Console/Client Portal, Auto Attendant, Conference Calls, Intercom, Voicemail to Email, Music on Hold, and many more features.

The basic plan provides the following features:

  • Unlimited User
  • 2 Channels
  • Single Number
  • Dedicated Hosting
  • Configuration and management

Choose your license and IP phones, you'll be up and running in no time.


Our shared hosting service provides the majority* of the functions of a dedicated plan but on a shared infrastructure. This means you can use a capable phone system with little effort and a reduced cost.

It features:

  • 2 Users
  • 2 Channels
  • Single Number

Factors that can affect service performance and reliability

Your phone service is supplied via the Internet and so is dependent on your Internet connection. Each call used around 100Kbps of uncontended bandwidth up and down. It is reliant on a fast (low latency) connection. If you are transmitting or receiving a large amount of data, the voice data may be delayed or dropped completely.

While every attempt is taken to deliver Emergency Service Calls (000 and 106), your phone service is carried across the Internet and third-party networks outside our control. As a result, we cannot guarantee that these calls will be completed.

Power Outages

In the event of a power outage, your Internet service may not function unless there is a battery backup unit installed. You should prepare for this loss and have the app installed on your mobile or tablet.


Security, Medical, Fire/Lift Alarm Services – You should contact your provider to assess whether your alarm is compatible with a VoIP service. They should be able to discuss available alternatives if your alarm is incompatible.

EFTPOS and Credit Card Services – These service will not work on a VoIP service. You should contact your provider to discuss available alternatives.
