There is Open Headset Interconnect Standard, https://ohis.org/ https://ohis.org/, for standard headset connection using RJ-45. But I can't tell if anyone uses it. I wonder if could make boards like this for different adapters. I sort of wonder if USB Audio would be a better way to connect headsets. Go from standard audio ports or headset ports to USB, and then USB with these connectors. The hard part is what to with the PTT pin. I guess the downside is power.
