With VoIP, you use an IP network through an ADSL Internet connection or other, to make or receive calls to / from terrestrial PSTN. You can even talk to people with a landline number using your computer, for example using the SkypeIn and SkypeOut service. PSTN includes telephone numbers and IP networks have IP addresses. How these two work together?
Answer: The answer is address translation. Your computer or VoIP device connected to the Internet has an IP address assigned to it. When you call a person on a fixed PSTN phone, your call is forwarded to the PSTN network via the telephone number of the person you call. And vice versa.
For phone users who want a type of VoIP is more or less as their existing fixed line with traditional phones, the most appropriate types of VoIP services are subscription and equipment services. They are intended mainly to households and small businesses. Upon subscription, the user is sent an adapter (ATA) and is given a phone number. This requires an Internet connection, which adds cost, but the overall cost is relatively much weaker. Added benefits are the many features that come with VoIP.
