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,
