No, they are the older IP300 and IP500s.  They're currently running 
2.1.2.0078.  I was going to move them up to the 2.2.0, but the firmware 
won't work on these older phones.

No configurations have changed.  I have been told that in the last two 
weeks, they've had power issues.  Burning up several circuit boards in 
the press room.
