enable audio share between facetime and recording software

Hello, I would like to learn if there is a way to configure/ set up my Macbook, audio interface and recording software to be able to share audio between ableton live and facetime.

Equipment: MOTU UltraLite-mk3 Hybrid, Ableton Live 9, Macbook Pro 13".

When I have a session opened and I am working on it, and someone calls me on facetime, then I am unable to hear any sounds coming from the ableton session, only facetime.

What is the correct way to configure this? Is it possible?

Thank you for your help.
