What do phone plugs look like in your country?
This is how they look like here












Paul, I don't understand much about phone system but I know that in britain too, they use 2 wires in residential phone sockets. About 10 years ago I worked on a phone system in Britain and it used 3 wires. One, I believe was for the ringing. Can you explain to me more about the differences, how it works and why it changed to 2 wires?
