Smartifying an old 2 wire door phone - possible?

heyho,
I have an old door phone kit with two inside units (Emos H1086, inside pictured just below)


one is up on the wall and works great, but it has two units, and I wanna make at least one smart. it sends the ring signal and the audio signal on two wires. I’ll figure the software side out as i go, I only need help to have it send the ring signal into HASS (or ideally the audio too, but that’s not a must).
ty in advance,
L
