Hi All!
I have a starange new problem on my otherwise tried and tested Vigor 2820VN. When I call or get called VOIP-to-VOIP, the router reboots within minutes. When I call landlines from VOIP or get called from landlines on VOIP everything is fine. I use Draytel.org VOIP.

I've tried flashing the router with rst. but that did not help....
I now put in the USB flash key to capture the LOG but the log shows no entries that can explain what happens.. I'm at a loss...

Any ideas?

That's probably a firmware bug, you can find out why its crashing by accessing it through telnet and then doing "sys ver dbg" there, then contact support with that, they might have beta firmware that fixes the problem you've got.

Do you have 3.3.3 firmware on the router?

Yes, I have the 3.3.3 firmware
