I have an old Chinese intercom system that uses an mobile app called VDP Connect to connect to my intercom via SIP, the app allows me to unlock the door. I would like to be able to programatically unlock my door but I am unsure where to start. The app requires a few credentials. I have to create an local account (profile) by scanning a QR code with the configuration details on the intercom screen then when inside my local network I am able to view camera and listen to audio as well as unlock the door from the app.
