We have also had this happen at client sites. I don't think it's a router issue, since we've had the same thing occur using a variety of different routers. There are 2 possible reasons for it: 1) The firmware version on the GXP2000 isn't doing DHCP queries properly - when it connects to the server to renew its IP, instead it thinks the server's given it a different one (which of course it hasn't). I'm guessing the phone drops the network interface then brings it back up. 2) The "auto check firmware every...." option was known to cause the phone to reboot in some firmware versions when the phone checked for new firmware/config from the TFTP server. We worked around the issue at one place by giving all the phones static IPs (and configuring them in the phones manually) and disabling "auto check firmware". At another location where static IPs would have been impractical (some staff take them home at weekends), we simply upped the lease time on the DHCP server to 7 days. Of course, you may find that simply trying different versions of the firmware resolve those issues. Regards, Chris -- C.M. Bagnall, Director, Minotaur I.T.
