I have searched and tried disabling FW check and all related settings.
I also extended all the default 3600 resync checks to a lot longer.

Hi,

Try upgrading to the latest version. I have tens of 504G operating without any problems.

How are you powering these phones? I had a case when a PoE switch was experiencing short-circuit problems on a badly wired cable, and was unable to provide enough current to power the phones on the other ports. Replacing the faulty cable fixed the problem. You can always try to power the phones using 5volts DC, 2A center pin positive power source and see if the problem persists.

Also I have a Linksys SPA-941 that has a public IP and reboots itself whenever someone tries to bruteforce into it by sending tons of sip registers :)

HTH,
Vahan
