[Asterisk-Users] DID Issue

[Mark Johnson]

I have a pretty strange problem.  I have about 100 DID's that come down 
a PRI from SBC in the United States.  On Friday afternoon, one of my 
DID's flipped out.  When you call it, the SBC operator comes on and says 
that the line has been disconnected.  I contacted them and they ran test 
and they are telling me the problem has to be on my end.  My problem is 
that the CLI never shows the number as called.  It seems to me it would 
show that ZAP channel ring and then say what it decided to with it.  
I've got nothing.  I even shut the * box down and brought it back up, 
same problem...

In the past, if I shut down a SIP device and you try to call the DID, 
I'm pretty sure you got a busy signal, not an SBC operator.  Anyone have 
idea how to troubleshoot this one?  I pretty sure it's a problem with 
the phone company, some type of translation issue.
