You are likely here because you own an OBi device. Traditionally, OBiTALK was designed as a remote configuration tool for your OBi hardware, however this tool was shut down on November 1, 2024. There has always been a way to directly configure OBi hardware via logging in via a web interface, but it did not work with the popular service provider Google Voice.
This new firmware for your OBi device, like other community developed firmwares for e.g. routers and Android phones, makes the current/future functioning of the hardware a bit more independent of the company that sold you the hardware. With it, your OBi device need not be dependent on the now-defunct OBiTALK. This new community-created firmware will continue to grow and evolve, increasing the useful life of the hardware, and adding many capabilities right now such as the ability to configure Google Voice without the OBiTALK Portal.
