If this changes the state of a hint, should hint watchers be notified? I think that would be expected, but I do not think it is done.</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">You are right. It wasn't in scope for what I needed in Pinana. I needed the initial check to set up the remote subscriptions. I'll look into it.</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This loop goes through the hints and gets a state value but doesn't store it anywhere. This function appears to be a big NoOp.</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">You totally misunderstand. This is where I actually fix the problem, Russell. By calling ast_extension_state2() I actually get the initial state for the hint - which Asterisk could not get earlier since the device state provider was not registered. It's a chicken and egg issue, and I want to break the egg... :-)</pre>

ast_extension_state2(hint->exten);
This is going to go calculate the extension state and return it. Since the return value is not being stored anywhere, it doesn't do anything. I would expect to see something like:
hint->laststate = ast_extension_state2(hint->exten);</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;">When the dialplan loads, all hints are initialized to a first state. If a device state provider is not loaded at the time, like meetme (or the new device state provider in chan_sip/Pinana), the hints are not initialized to the initial state. This affects all hints that have an initial state, like a registration in chan_sip, which is a state for "presence" subscriptions using SIMPLE in chan_sip.
The patch in /svn/asterisk/team/oej/pinana-initialize-devstate-1.4 fixes this by re-initializing all hints using the new device state provider after registration of a new device state provider.</pre>

Without this patch, the device state provider hints would never initialize properly when ASterisk starts, since the dialplan loads before chan_sip.</pre>
