Copy phone number of ACTIVE caller

Currently we can only copy the phone number of the caller once he/she has hung up using this method (see gif)

It would be great if we could simply copy the number of an active caller. A simple "right click on the phone number calling you" and "copy" is all that is needed.

That way we can get the client's phone number into the CRM and see if they already have any account with us and we can then help them accordingly. Currently the manual "type out the clients number" means longer times (not a simple copy n paste) and possible wrongly typed phone numbers.
