That will prevent a dynamic hint from disappearing after a 'dialplan reload' because Asterisk thinks it's not being "watched" by anything. We should also unsubscribe from the hint when the agent is removed from the queue.</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I have tested this patch by using either a dynamic hint, a static hint, a local channel or a SIP device as a queue member's 'state_interface'. I have also added/removed the queue member both through Realtime and the CLI.
I've had this patch on about half a dozen 1.8/11 production systems (all averaging a thousand users each) for a little more than a month with no apparent issue.</pre>
