[asterisk-users] SIP response 480 "Do Not Disturb"

[Tomer Horn]

The only solution that I found for this is to use Asterisk 1.4 with 
devstate backport  
(http://svncommunity.digium.com/svn/russell/asterisk-1.4/func_devstate-1.4/) 
and use the hints and to determine if it's inuse (or any other status) 
before the dialing - in order to generate a proper reply. I didn't find 
a way to handle the SIP 480 reply using Asterisk 1.2 properly.

Note that it's an idea I was about to run but I didn't get to it yet. 
devstate on test machine compiled fine & seems to be working from first 
sight.
