Frequently asked questions

Do I need internet?

Yes! You will need a reliable internet connection. Crazytel does not sell internet products. There are many internet providers to choose from if you don't currently have internet.

What happens if my internet goes down?

Your SIP registrations will drop. Call forward will still work if it has been configured through our portal. We suggest if your telephone is essential for you to invest in a 4G backup service.

What is the quality like?

If you have a reliable internet connection, the quality is just like your mobile phone or your PSTN line (and often better).

Is it reliable?

Yes! Crazytel has a quadruple redundancy network - we are one of the few Australian companies that has such an extensive enterprise failover network.

Is there a minimum monthly spend?

No! Our residential SIP trunks are 100% pre-paid pay as you go. If you don't use our service, you don't pay! If you have an active DID(s) on your account, you will still be charged for your DID's monthly fee regardless of use.
