Explanation
VoIP stands for Voice Over Internet Protocol. It is a commercial technology that has been adapted by amateurs to link radio systems together. VoIP is simply a method of delivering voice communications over the internet using digital techniques.
In amateur radio, VoIP systems like EchoLink or Allstar are used to link repeaters or stations over the internet. This allows an operator in one country to use their local radio to talk to another operator in a distant country whose radio is connected to the same internet-linked system.
