I have an Obi 202. It regularly stops providing dial tone while being provisioned to Google Voice on both ports. If I reset the unit, service resumes.
When the unit stops working, and I check it, the power light is dark. However the two line 1 & 2 leds are green, as is the WAN data led.
I've searched a bit and have not found any example of this issue on the board.
Earlier I think I may have reverted what was described as a more stable firmware, and this helped for a while, but then the problem reoccured. I now see my current firmware is 5921EX that appears to be the latest. The earlier firmware I may have reverted to is 5757ex. The unit no longer allows me to revert to and load 5757ex. It gives a checksum error.
Is there a way to revert to the 5757ex or other firmware? Is anyone familiar with this issue (no dial tone and power led dark, but others green?)
