Call forwarding with hiding the caller's number?

Question

Telephony

Tell me who you can buy a virtual number from, so that when you forward a call, the subscriber does not see the caller's number.

Answer 1

In my opinion, any provider.
You agree that you have one trunk without a number - the telecom operator will substitute a free one from the pool, and randomly choosing it.
And you stipulate that incoming calls are not needed for this trunk
