VoIP Gateway

 

This VoIP gateway is how your current phones in a small office or a home connect to the VoIP network and the PSTN at the same time. The phones plug into the gateway via a traditional telephone plug (known as the RJ11) and then into the phone line. However the gateway also then plugs into the internet, granting access to the VoIP network as well.
