There was a storm last night and the power blinked for just a split second. Afterwards, my phones show "In Use". The Phone Port Status says "Off Hook". If I disconnect the phone line from the Obi200, the phones go back to normal, but the Obi still thinks it's "Off Hook". I tried rebooting it twice and unplugging its AC adapter also. While it's booting, the phones no longer think they're in use, but once the Obi200 boots up, they go back to thinking they are.
Is my Obi200 fried? Does any of this mean anything?

EDIT: Tried a different 12V 1A AC Adapter. That raised the VBAT in parenthesis to 11.9V, but the one not stayed 14V.
