When a user login/logout to/from queue via *45 (FreePBX queue login default feature code) or a user is added/deleted statically via the FreePBX interface, the "new" agent doesn't apprear in the queue's agent list of FOP2. I have to do a "/etc/init.d/fop2 reload" to update the agent list.
I'm using FOP2 2.31.11/Asterisk 11.4.0/FreePBX 2.11.0.11
