I am having a problem where every once in a while we have certain Cisco 7960 (SIP v7.4) phones power cycle on their own. This can happen right in the middle of a conversation. Looking at some of the Cisco logs shows no error messages or direct problems. We have tried multiple things, such as placing the phone on a UPS and having it connected also via a Cisco 3524-PWR switch. Both still cause the probems.
Anyone have any ideas what else i could look at, that might be causing these phones to reboot on their own.
