Ring to open in the outdoor

Since the M72 tegui wasn’t working (couldn’t get the opening singal), I worked it around making it as an outdoor and soldering around the opening button.
My question is if there is a possibility to make the calling signal useful (ring to open or getting a notification) in this outdoor mode (which works as a button)

Yo sí pude conectarlo con ring to open pero la notificación entrante nunca me funcionó.

Mira uno de mis mensajes donde explico todo. La pena es que no funcionan todas las prestaciones. Algunas las considero clave, como avisar de que alguien llama. Solo funciona Ring to open.
