Swiss VoIP | Swiss VoIP Solutions Solutions:
Unfortunately a very big problem and different depending on the country. In principle, the regulations of the country where the numbers belong apply. It is almost impossible to control that someone's own number is used for spoofing. Unfortunately, there are still many providers who earn too much from this business and become rich.
We all carriers, resellers, providers must actively monitor and prevent spoofing!
We are working on filter solutions but this is like a computer virus...... the spoofers are faster.......
