I'm using an OBi202 with both phone ports configured to work with
voip.ms. At some point in the last week one line quit working, then a couple days later, so did the second line. No configuration changes were made - I wasn't even in town and no one else messes with it. From everything I can see - via OBiTalk and on the device itself, it's online; both lines show as registered. However, I get no dial tone from either port. I've upgraded firmware, rebooted a couple times of course, and tried an analog phone directly into both ports. Nothing, not even DTMF tones. I can't even dial commands that work directly with the OBi, like the 222... test number.
Is it likely hardware? Are there any other troubleshooting steps I can take?
