That's almost as good as your #1 carrier for your number 1 destination  
not responding to SIP requests and you talk to their NOC and they tell  
you its a "billing" issue and contact your sales guys.. 2 hours later  
it turns out that, oh their SBC really was down and it's not a billing  
issue. so sorry....
