Hardware

You will need to use a SIP NTU, which we will provide, to connect your fixed voice telephone system to the Telstra Business SIP service. There are different SIP NTU models available based on the number of voice lines you need and the type of interface your fixed voice phone system uses (BRA, PRA, or native SIP).

The SIP NTU can be installed by a Telstra Professional, a nominated Telstra Partner, or you can choose to install it yourself.

You can pay for the SIP NTU either upfront or in instalments over up to 48 months the term of your contract.

Telstra Professional Install

You can pay for a Telstra Professional Installation of the SIP NTU for a fee of $220.

If you cancel, we will charge you an Early Termination Charge (ETC). The ETC is calculated as follows:

Minimum monthly charge multiplied by the number of months (or part of a month) left in the contract term, then multiplied by 30%. Additionally, you will need to pay any outstanding hardware repayments. 

Sometimes, we might change your plan, including the price and what’s included, or move you to a new plan that might cost more.

If we think the change or move will affect you a lot:

• we’ll tell you at least 30 days before making changes or moving you to a similar plan.
• if you don’t like the changes or the new plan, you can cancel your plan. If you cancel, you’ll need to pay for remaining hardware or accessories in full.
