6. The script will ask if you want to control an TP-Link smart plug(s). This can be used as an "In Call" indicator. The use case I have for this is a TP-Link plug outside my office door in the hallway. I have a small red night light plugged into the TP-Link. When I'm in a call it turns on, when I disconnect (with the script) it turns off. Or it will turn off when not in a call and you run the script to change the volume setting.
