what you need to know

Our standard Terms of Service apply to all services. Additionally, the following terms apply to VoIP services:

analogue telephone adapter

An Analogue Telephone Adapter (ATA) is a device required to convert the digital signal to analogue so that you can use your existing telephone handset. DCSI offers an Obihai 100 VoIP ATA for $49.00 which is pre-configured for your service.

CSG Waiver

When you apply for a VoIP service, we will propose that you sign a form agreeing to waive your rights under the CSG standard. You are not obligated to waive your protection and rights under the CSG; however, DCSI may choose not to supply a VoIP service to you if you do not agree to wholly waive your rights.


DCSI does not provide any service assurance on VoIP. It is important for you to understand that the service may not function if there is a power failure, your internet connection is unavailable or performing poorly, or there is a problem with any of the hardware. We recommend that you have an alternative communications service (such as a landline or mobile phone) available in case of emergency.

plan changes

Change your plan at any time without incurring any additional fees. Changes will take effect at the start of the next billing period.


If you move house, all you need to do is let us know your new address so that we can update the Integrated Phone Number Database (IPND). This is a legal requirement and is vital so that emergency services can provide assistance – it is not the same as a public directory like the White Pages.

informed consent

For your first VoIP service with DCSI, we will need you to download and sign the Informed Consent for VoIP Services form, and return it to us before we can activate your service. Click here to download the form (PDF)


You can port a standard local landline service phone number to DCSI. Additional terms and some fees may apply. See the Porting Authorisation Form (PAF) for more details.

When your VoIP service is first activated, you will be assigned a temporary number. We strongly recommend that you test your VoIP service with the temporary number for a week or two and ensure you are satisfied with its performance prior to porting your landline number. Reverse portability – porting the VoIP number back to a standard landline – may incur a fee of up to $299, and in some cases may not be possible at all.
