Hi, RonR, thanks for your reply.
Now it is connected ( Do not know how.) The problem is I lost the dial tone. Here is what happened this morning.
Both the power led and phone led are solid green. I picked up the phone. No dial tone. Tried ***1 and other numbers, nothing happened.
Logged into the Obi dashboard. I can see the device connected. Saw a icon for updating the firmware. Was able to update the firmware but still no dial tone. I reset the device via holding the reset button. The power led flashed and the device rebooted.
The status on dashboard became "online unmanaged" and the google voice service became "service not configured". I reconfigured the google voice. It didn't help. Found a post online about the unmanaged device. He solved it by deleting the device and readding it. Deleting the device was easy. However, I was not able to add it back cause I do not have the dial tone. No response no mater what I dial on the phone.
I found one post about this "Lost dial tone after firmware update".
