Seeing that the OBi 100/110 are EOL, and the Google Voice service no longer works with the last official firmware, has anyone experimented with creating custom firmware for the device?
The Google Voice issue has been identified as a SSL/TLS certificate issue, in theory making a new firmware based on the prior version but with updated certificates wouldn't be too hard, setting aside legality issues about modifying the existing firmware.
Is there any interest in creating open source firmware for this hardware?
