This is long over due because I've been living with this issue for a while.Time to ask.
I have a SPA3102 with a local VoIP service. I do not have it attached to an active PSTN line. For some strange reason the unit is resetting itself. After 4 minutes the power light blinks for 30 secs (ish), then the internet followed by the phone LED's turn off and the power light turns red. The unit resets and reconnects to the internet then the VoIP service. I've read the admin manual for the unit with no luck pertaining to fixing this quark. I have also tried disabling the VoIP service, the unit still resets in the same fashion. I have even disconnected the internet connection. The unit resets (diferent light combinations, but the web interface Elapsed Time confirms that its resetting). The one thing I have not done, is reset it to the factory settings because I'm afraid of screwing up my VoIP service.
Any ideas? Solutions are good too.
Unfortunately I don't have the ability to update/modify your account, but I will attach the syslog server to this post for you. :-)
The factory reset will definitely wipe out all configs, but if you back it up first, you should be safe. Per Alberto's last post, you could run a syslog to keep from resetting the device. However, if the syslog doesn't reveal problem, then a factory reset will be your best bet.
