120x T46G (FW 126.96.36.199 / 3CX 12 sp6.2) Every so often a user reports the phone is "rebooting at random". It seems to reboot (crash?) when the device receives a new IP from a DHCP server. I am using 2x 2008 R2 WinDNS servers with ip helper and PoE. Anyone else run into this or have any suggestions? thanks.
