Opener compatability with :Hager LCA01F

I try to figure out if the Opener is compatible with my :Hager LCA01F. The LCA01F is a dect handset that functions as an intercom for my main entrance. My main entrance is a gate in the garden.

I finally found an English manual for the system. From page 22 onwards it shows some wiring schemes. From what I comprehend I think it is possible to use the opener functionality, but will it be possible to talk with someone who rings the bell? I’m not tech savvy enough to be able to make sense of it.

Here’s a link to the manual I found:

Hi! What I see on this manual, this is a analogue intercom, so no problem to use a opener with it.
