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,
