A computer powered by VoIP telephony can make numerous telephone calls at the same time using a computer program. This simply tries out the entire number block. The computer program begins making test calls at +41 79 000 00 00 and ends at +41 79 999 99 99. The computer program then feeds a database that stores which telephone numbers in this number block are valid and which are not. Valid telephone numbers are all telephone numbers where a person picked up the phone during the test call (green button).
Faking phone numbers is now very easy thanks to VoIP telephony. See:

I receive these “police call” calls every 4 to 6 months. Last time with an Arabic number, after pressing the red button (hang up the phone), it rang a few seconds later with a Swiss mobile phone number.
3 months later
I received a call today from the mobile number +41 77 446 ** **. When I answered the call, a computer voice started in English and said something about Swisscom Emergency Police call…but after 30 seconds the call ended. I’m having a hard time assuming this was some kind of fake call?
Has anyone already received something like this?
Yes, ignore things like that. Swisscom Emergency Police Call… they are becoming more and more inventive a la Hollywood! Have you turned on the call filter? If not, be sure to turn it on via your cockpit: cockpit.swisscom.ch. You can also block such numbers there manually if necessary. Once you have answered the call, hang up immediately! The general rule is… never call back such unknown numbers yourself. Even if you didn’t answer the call.
@Greittiejeu73 Of course it’s a fake call, I and my colleagues have already received it. just like the call from the Federal Police Department 🤣.
