NUKI Opener: BT-344282 ring supression upstairs hallway bell

Hello,

i have a BTCINO BT-344282 intercom system. which was cabled as shown below

BT-344282-Start

I managed to get the door opening, ring to open etc to work by cabling it like shown below.
BT-344282-Nuki-Basic
The only thing that doesnt work is ring suppression in this setup. so i tried the following setup.

BT-344282-Nuki-advanced

The ring suppression still doesnt work. i can disable the rining on the intercom itself for both setups and i get the alerts when somebody rings the doorbell downstairs. The problem is really when i switch of the sound on the BTCINO, the bell next to my apartment door upstairs stops working and no signal is given to the nuki openener. I thougth that maybe with doing the setup below i would be able to capture the rining of the upstaris bell but unfortuantly not.

BT-344282-Crazy

does anybody have an idea?
