Summary:                    Crash in device state handling
Description: 
I finally had it set up for a backtrace when it happened, with verbose
logging to file turned on.  The system was in the middle of a reload when
the crash happened.  Here is the backtrace info.  I'm not 100% sure if i'm
supposed to post this here but the asterisk debugging page on voip-info
said submit a ticket.  I confirmed with a user that they had dialed their
phone when the crash happened, and that at that instant everybody else said
their phones had died.  The dial is actually a scripted button which uses
the AMI to originate the call.
