The first thing to understand is that some aspects of VoIP are regulated and others are not. The regulation applies when VoIP calls are connected to existing PSTN networks, allowing you to make and receive calls from regular phones. This ensures that traditional service providers are compensated correctly for using their infrastructure. It also ensures that VoIP service providers meet certain standards for receiving their calls on PSTN networks. For example, the E911 standard for emergency calls and the E.164 standard for number allocation. This also means that you can expect a level of call quality that is equivalent or close to that of PSTN service.

If IP calls are made exclusively argentina whatsapp number data within the Internet – when it is computer to computer or IP phone to IP phone – then it does not need to be regulated. Therefore, the quality and reliability may not be as good as with regulated services. Also, users of the service will likely have a more limited set of features available.
