Opener wiring help unknown intercom

I wonder if any seasoned veterans can assist with the wiring and config of my opener
I have an intercom similar to this

Though my testing I have worked out the following pins

1 white and blue - Unknown
2 blue and white - Unknown
3 white and orange - 12V DC -
4 Orange and white - 12v DC +
5 Green and white - Lock open
6 white and green - Unkown

I assumed 1 and 2 were mic and speaker. However, the speaker is still active when disconnected. I also assumed pin 6 was Call

I currently can only get the door open to work by pressing the buzzer button then open in my app

Does anyone have any suggestions?
