Fop2 queue agents show DND
I'm running FOP2 version 2.31.27, FreePBX version 188.8.131.52 with asterisk 16.6.2.
I have a queue with 3 agents which all works fine and FOP2 shows the queue and all three agents. However, once an agent uses the DND feature on their extension, the queue agent status icon changes to show DND. However, after agent removes DND and they again taking calls, queue agent status icon stays showing DND. I have tried restarting FOP2 server service, flushing browser cache, tried the FOP2 Presence changes DND plugin, querying asterisk database:
asterisk -rx "database show fop2state" 0 results found.
and I still cannot get the status of the agent in the queue to change. So, not sure why icon is never changing back to reflect available?
