Any idea why my phones random stop working? Sometimes they just go blank and sometimes they actually reset. It could last a couple minutes or a couple of seconds. I am the only person here at this time that could be in the call managers screwing around, and I am not. The network is fine, most devices have gigabit connections to the backbone and the servers are virtualized on the UCS that has 4 10G connections. Pinging across the network is less than a ms round trip delay each time. Ideas?
