I am currently running CME V 12.4(11)XW7 on a UC 500 and keep having random phones drop into the logged out of hunt group state. The Hlog key is disabled. Everything is working as expected apart from this and it is ver frustrating. I have to restart the phone system to clear it. The problem is happening at least once a week. Even deleting the ephone in question and rebuilding it does not clear the problem.
Any advice would be greatfully recieved.
