Call Center Recordings

Good Morning,

Our contact center people each have a personal line as well as using the contact center lines.  sometimes they may use their personal line for recorded calls with a customer.  The supervisor of the department wishes to be able to listen to the recordings from the personal lines, but when she goes in to Phone system management under the logs, she doesn't see the recordings.  She can see the recordings made from the contact center under contact center management.  does anyone know what access is needed for her to see the personal line recordings under phone system management?

Thank you
