I wonder - when this will be available from Realtime.. Managing more
than 50 users makes static config a nightmare, and AFAIK there is no
ways how to create hints with variables/extension masks. So, it is
logical to ask for hint support in Realtime.

I fail to see the problem. An #exec in the dialplan and
a custom script which reads your database and generates
the hints does the trick.
Maybe a bit too complicated for the newbie but feasible
for larger installations.

AFAIK hints are supported in Realtime:
Set the priority as -1.
Set the app as the hint.

That's all well and good, but as the entry is in the database, it is not able
to keep a pointer to a routine in memory (or else the pointer may become
invalid after restart, without clearing the database, or else you have
multiple servers, or .....)
Having a hint entry is only half the battle. The other half is in keeping a
registry of function pointers to call when the state of the device changes.

Oh, haven't seen anything like this, and not even any queries in log
that asks for "-1" priority Any more docs on this?

I'm not very familiar with internal structure of device states,
however i think this is not so hard. Why would you need to keep a
registry, i think you should just do SELECT whenever any device state
changes, to find out what to update.
While on topic - may i ask for help.. For queues with dynamic members
(i.e. Local/200@from-queue), if i would create something like this (in
realtime of course)

No, you need the REVERSE direction. You need to know what code to notify
when the device changes (the device does not need to know that its state
changed -- the device is what *initiated* the state change).
And that code is not always specifically pointing to a device. In some cases,
the code is notifying an application that a device changed, which is why it's
a function pointer callback that is registered to the device hint.

I have a small question: other than a phone (ie. SIP/something), what else can
I use as "app"? Can I handle the change via some custom code?
TIA,

There are a number of things that can provide "device state" in Asterisk. That
includes "real" devices such as SIP endpoints, or any other channel driver.
However, it also includes things like monitoring the state of a space in
parking, or the usage of a MeetMe conference. I have also written a small
dialplan function which lets you create custom device states. A lot of people
use this for things like having a light on the phone that reflects whether the
agent is logged in or not.

Thanks a lot for the info, I already read the first article, and it's great to
know that DEVSTATE can be used in 1.4.
But my question was different, my poor english doesn't help me. :(
In your article I read
"For example, when someone subscribes to the state of extension
1234, Asterisk knows to give them the state of the SIP phone SIP/myphone.
exten => 1234,hint,SIP/myphone"
Suppose that I want to write to a database the state of all my extensions, in
order to display it in a web page.
How could I do it using the hint mechanism?
Thanks again,

Just create a module that subscribes to every single device and when the state
changes, your callback will get an event with the device name that changed.
You could then update your database with an SQL query (or whatever else you
like).

Just create a module that subscribes to every single device and when
the state
changes, your callback will get an event with the device name that
changed.
You could then update your database with an SQL query (or whatever
else you
like).
The manager interface is our preferred connection to Asterisk from
third-party
modules. The AMI will report all device state changes, so you can
create an
app that updates your database based on this information.

Thanks to both of you for the hints. :)
