I have found that using a flag system works wonders. Luxafor makes a USB powered light that I have attached to my station. Green means chat me up. Red means leave me alone. I have it set to an interval of 25 minutes red to 5 minutes green. (Like pomodoro timer). Took some time to get people on board but now its great and has expanded to not only my entire team, but other teams in the org.

Note: not in any way involved with Luxafor. Was given their product by a friend.
