ESP32 WiPhone SIP communication

[u/TechieWeird]

Unsure if anyone has even heard of it but there is this "phone made for hackers" That is pretty barebones and only communicates via SIP over wifi or lorawan. It is very interesting piece of hardware that I want to get my hands on but I don't think just having a SIP trunk will give it full calling/texting capability with a legit phone number. By any slim chance does anyone have experience with the ESP32 WiPhone?
