I have the most common esp32s WROOM board, and I want to make an HFP unit, not HFP ag. I had been googling for it for a considerable time and I already found the hfp_hf example for esp-idf. However, it doesn't really work for some reason with my phone. It's being recognized as a handsfree device, and I can send the AT commands, but my phone still uses the phone's speaker on a phone call, and sometimes the dialer app hangs when I want to select the handsfree device. This person who also attempted that mentions it in his youtube video and he uses BTstack api ported to esp32 instead. I can't get that to work either because I don't quite understand what IDE and toolchains he used (I tried importing everything to esp-idf eclipse, didn't work). I also found the last link you shared, but will that work with my board? It says it needs a Lyra board.
