My father once had a funny digital realisation when he (German) phoned his German friend from Australia while not knowing that said friend was in Australia as well.
So the call went from Australia to Germany to look for the German phone and roaming back down to Australia to make the connection. I wonder if the actual signal traveled to Germany and back to Australia or if it is routed locally after establishing where every participant is.
Probably returns to China.

Hopefully he didn’t have to pay the long distance fee.
