In most cases such a message or similar message occurs in case of problems in the network area. This can be on its own connection/connection, or on the network itself.
It's just that it's "tuting" four times in the meantime. I don't know that.
To be able to exclude or verify your own connection/connection as a problem, I would simply test several calls on different connections. The best with different options and possibly also different mobile telephone providers.
If the message occurs in all cases, it must be on its own connection and would then call to your provider
This is somewhere on the way from you to the phoned device.
In the case of a mobile phone, it can also be, for example, the termination of the connection at the moment or an overloaded mobile telephone mast.
Or with a “call” via a messenger such as WhatsApp, that the recipient has not unlocked any rights for voice calls on his device (WhatsApp, for example, has not allowed access to the microphone).
"Suited"? Or "transmitted"?

If it "sounds", a connection setup is possible in principle.
It just didn't take off or the conversation was blown away
