We purchased and installed a new Obi200 earlier this year when Obi100 was no longer supported; the system has worked perfectly. We have SP1 for Google Voice set as usual without other services.
This week, all calls (incoming and outgoing) have started dropping after 5 minutes. I updated to the most recent firmware, which didn't help, so I followed Steve in Washington's steps for unplugging, deleting the device, reinstalling, reconnecting to Google Voice (I'm not detailing every step, but those are the broad strokes of what I've done). The current firmware build is 3.2.2 5921EX.
The calls are still dropping. Are there other suggestions for this particular problem?
Thanks for your help.
ETA: Sorry for the multiple posts, I kept getting an error about mail server response codes. I've deleted the duplicates, AFAIK.
