Bought our OBi202 back in May 2013 and it's been rock-solid. We use Google Voice as the main provider and Localphone for international calls. Virtually zero issues for 8+ years. For the past week or so, however, the OBi202 more often than not (but not always) will crash and reboot itself if we try to answer an incoming call, and it rarely (but not never) displays the caller ID anymore. Both began about the same time. Nothing whatsoever has changed that may have caused these issues in terms of configuration, connections, etc.
To troubleshoot, I've disconnected and reconnected all the lines. I've done a backup, downloaded and installed the latest firmware (it hadn't been updated in ages; worked great and I didn't want to mess with it), even reset everything and restored from the backup. Same problems.
Before I splash out for a replacement (it's more than paid for itself, to say the least) does anyone have any other suggestions about what it could be other than a hardware issue with the device itself? Thanks in advance.
