How to determine the operator after the entry into force of the law on the abolition of "mobile slavery"?

Question

Asterisk

Now, in order to save money, several different SIM cards are inserted into the GSM gateway for calls via Asterisk. After the law on the abolition of "mobile slavery" comes into force, it will no longer be possible to trust the first digits of the phone to determine the operator. And since the number is no longer an indicator of the operator, it means that communication costs will increase in companies where many calls are made to mobile phones.
Actually, I wanted to find out the opinions of the habra community about what ideas anyone has about this. And what does this law "carry" for you in general? Or maybe you don't care, because, for example, your company uses a different way to save costs on calls to mobile numbers.
