How does VoIP work?
When you call a number, a VoIP adapter logs on to a routing server. The VoIP adaptor is provided by your VoIP service provider. It might be a software program, a phone jack that plugs into your computer or a dedicated VoIP phone.
The routing server looks up the IP number that’s associated with the destination phone number and makes the connection. If the destination number isn’t using VoIP, the routing server recognizes that the destination number is a Public Switched Telephone Network (PSTN) phone and routes the call through the traditional Public Switched Telephone Network.
