fwiw, I updated my obi110 a couple hours ago and now seem to have intermittent issues with my device. I updated via the obitalk website, and now, every so often, my obi power led will turn red, and I won't be able to temporarily place calls, then after about 5 or 10 seconds, the leds will turn green and it will start working again.
I have since moved my obi to another switch and will keep an eye on it to see if I still have issues. I had been using my obi for a couple months without issue before the update.
***EDIT***
Still having issues after moving the device to another switch. Unplugged the phone from the analog port, still had the same problem. Unplugged the ethernet port, problem stopped occurring. Odd.
I tried to find some consistency in the intervals between when the problem was occurring and found that it appeared to be happening approximately every 20 seconds:
10:44:28
10:44:46
10:45:07
10:45:35
10:45:59
10:46:27
10:46:51
10:47:16
10:47:36
I suspected that this may be some sort of arp related issue, so I rebooted one of my switches, seems fine for the moment. I didn't see any changes in the newer version of firmware that I would suspect to cause this sort of behavior on the udpate post here -

In case anyone is wondering, my internet connection is working just fine, no other devices are having any issues.
