Makes perfect sense, thanks for your help.

Ok, doing that, I see this activity:

Seems that FOP2 reflects when DND is activated, but not when it's deactivated. I will have to use the feature code to get FOP2 to reflect available again, and sometimes I have to use the feature code twice. I'm wondering if there are too many events for FOP2 to keep up?

Which Debug level? I've added the "all" permission to manager.conf and restarted FOP2. It in fact does register the DND, but when I change back to available, it does not register. I have to dial the feature code to toggle the status in FOP2

I guess I was wrong and it does update astDB, but is maybe using a custom presence. See this thread: http://forums.asterisk.org/viewtopic.php?f=49&t=95036

We use Digium D70 phones with FreePBX. I have been running FOP2 for a couple years now, and we'd like to start taking advantage of presence. What I'm learning is that the presence icon will change on FOP only if setting DND via a feature code. Presence does not update when selecting DND via the soft-key on the actual phone. Is it possible to have FOP2 recognize when DND is set directly on the phone? I do know that hints are created for DND, but I don't know that FOP2 uses hints.

Thanks you.
