Where can I register a virtual phone number?

Question

Telephony

Please tell me, I need a virtual number to publish it on the site to communicate with customers. It is necessary that calls to this number be recorded and from it it would be possible to forward them to other numbers, for example, if our operator has changed, we will forward calls from a virtual number to the mobile number of the operator. I would also like to call from this virtual number, but it is not clear how to implement all this?
