VoIP services are provided by carriers and carriage service providers (CSPs) using telecommunications networks to supply communications services to the public.
The ACMA has classified VoIP services into four types:
Peer to peer – internet only, calls do not use the traditional telephone network, the public switched telephone network (PSTN)
VoIP Out – a service where calls can be made from the VoIP network to the PSTN
VoIP In – a service which allow calls to be made from the PSTN to the VoIP service using a telephone number
Two way – a service which allows calls to be made both ways between the VoIP service and the PSTN using telephone numbers.
A carrier licence is needed if you are installing your own transmission lines or radio facilities.
CSPs have a number of legal obligations, which are set out in the Telecommunications Act 1997 and the Telecommunications (Consumer Protection and Service Standards) Act 1999.
