Are you making regular phone calls or VOIP?

Check if the problem is due to a third-party app, boot on safe mode and try to place a call.

This error is purely related to the network provider and it is not related with your Android system or because of an error in your smartphone. Give your network provider a call and see if they can fix it, but usually it gets fixed eventually due to some maintenance in one of the provider's towers.
