I live in France. About 5-10 times, once every 1-2 months, I receive an automated computerized call that listens to me say "hello" there is silence for 5 seconds, and then there is a voice recording of a British woman saying "good-bye".
If it isn't a sales call or a phishing call, then what is this kind of call? Why do I receive this call with a UK automated voice from France on a French ISP landline number?
IF greeting=="Hello" THEN main() ELSE endcall(). – dotancohen Jun 01 '15 at 14:05
