So, sometimes when an agent logs into FOP2 the queues won't show all agents. For instance I have a queue with 4 static agents. They are all available but the queue only shows 2 of them. I reload the panel and then SOMETIMES all 4 agents show up, no other changes made. And I THINK (but haven't verified) that they will eventually just show up on their own after a certain amount of time, sometimes quite a while.
I don't manually define any buttons, queues, or anything like that. I installed and ran through the instructions on integration of FOP2 with FreePBX. I have however upgraded FOP2 and FreePBX over multiple versions over time.
Any idea why this might happen and what I could look at to help determine the cause.
