Regulated and unregulated

The first thing to understand is that while some aspects of VoIP are regulated, others are not. Regulation applies where VoIP calling connects to existing PSTN networks, allowing you to make calls to and receive them from conventional telephones. This ensures that the traditional service providers are compensated correctly for the use of their infrastructure. It also ensures that VoIP service providers meet certain standards for their calls to be accepted on the PSTN networks. For example, the E911 standard for emergency calling and the E.164 standard for allocating numbers. It also means that you can expect call quality levels equivalent or close to those of a PSTN service.

Where IP calling takes place solely within australia whatsapp number data the internet – when it’s computer to computer or IP phone to IP phone — then it doesn’t need to be regulated. Quality and reliability may therefore not be as good as when using regulated services. There is also likely to be a more limited feature set available to users of the service.

Some providers span the gap between these two fields and this is where you need to be careful when signing up for a service. VoIP providers may have varying levels of IP interconnection in different parts of the world and so you need to understand what you’re going to get when you sign a contract.
