I have an Obi100 which works perfectly.
I also have an Obi100 set up for my parents which worked perfectly until this past week. Now it is showing as offline in the OBi dashboard and it is unable to place or receive OBi-to-OBi calls, and it is unable to complete a call to the Echo Test. However, incoming and outgoing calls on SP1 using Google Voice still connect just fine.
I went over yesterday and reset the DSL router and the OBi 100, and updated the firmware. Everything worked. Today the problem is happening again. Any ideas about what I can change in the setup next time I go over to fix it?
