We have a Nortel/Avaya CS1000M R7.5 VOIP system, and some users phones reset searching for server they come right back up. This has been going on for 3 days now, and our maintenance support contractor keeps referring to our network. We checked our network, and everything looks good, I reset the Signaling servers, and we still have the same issue. it seems like it effects some more then others, it seems to be more phones resetting each day.
