This afternoon, two different Obi's started showing as "Offline" even though they can still make calls. Even though they can make calls using GV and Callcentric, I can't call other Obi numbers and I can't call 222-222-222. So, it looks like something may be broken on the Obi end.
I have a spare Obi, so I tried doing a factory reset and was unable to connect it using "Add Device." So, that's another indication that something is wrong on the Obi end
