Ring Intercom - Pinout

Dear all, I have a question regarding the RING in analog mode. When answering a call from the app, is there a pin on the connector that goes HIGH or LOW (other than those related to analog audio - mic/speaker - and door opening)? I'm using a 2Voice system, and in digital mode, it seems to only recognize the first door chime (not any additional ones), limiting functionality to a single door. However, by switching to analog mode (directly soldering cables to the mic/speaker/door key/call-in terminals), I can bypass this limitation. Another issue I’m facing is that my intercom is hands-free and requires a button press to enable conversation. If there is a pin that changes to HIGH or LOW when answering a call from the app, I could build a small circuit to simulate the button press. Thank you in advance!
