Also, I'm sure you've probably checked on this one, but are the phones 
registered with asterisk?  You can make outbound calls on them without 
them actually being registered.  I'm assuming you can still get in and 
see the CLI.  What does "sip show peers" look like?  What does
"sip
show peer xxx" show?  What does the CLI show when you dial a phone?
