Upgrade your phone system from copper to the cloud

As technology has evolved, the internet has enabled businesses to replace their copper phone lines and deliver high-quality calls at just a fraction of the cost.

Calls placed over internet protocol (IP) are incredibly cheap (if not free), so moving on from traditional phone services to an Aussie Broadband SIP Trunk Service will be a money saver for your business.

You can bring your existing phone system and phone numbers into the 21st century without having to update all of your hardware. To make it even better, we’ve got two great plan options to help you save on your bill.

Frequently asked questions about our SIP Trunks

How many channels can I use?

Aussie Broadband can provide up to 8 channels with our SIP Trunk product. There is a minimum requirement of 2 channels.

Will I require any additional hardware or equipment?

For our SIP Trunk product, you will require our 8 Port ATA Analogue to VoIP Adapter. You will need to pay $18 per month rental for the adapter, which remains the property of Aussie Broadband and must be returned on disconnection. If you require an adapter, professional installation costs will also apply.

Do I have to bundle anything with the service?

You will need an active Aussie Broadband nbn™ internet connection. This is a separate service and its costs are not included on our SIP trunk plans listed here. Internet connection costs will depend on the speed and data plan that you choose.
