This has been happening from time to time. In our wallboards, we start seeing more "Agents Busy" than there are. For example, at the moment, I see 3 agents busy for a queue but only 1 of them is actually on the phone with a customer. The solution I've found is just restarting the 3CX server. See attachment, as you can see the wallboard says 3 agents busy but only one is on the phone. Also, queues statistics reset every night at 12 when no one is in the office. Any suggestions?
