[cisco-voip] Call Manager 3.2 problems

[Ryan Ratliff]

Did you happen to check cpu utilization on the subscribers where the 
phones experiencing the problems were registered?  Failure to get 
dialtone basically means the message from the CM telling the phone to 
play dialtone was never received.  This is either a network issue or 
the CM just plain didn't send the message (ie high cpu).

I got experienced an extremely strange issue with my Call Managers and 
I was looking to see if anyone had any insight. 

  This morning we started getting busy signals on some of our inbound 
calls.  These were sporadic.  I tried looking at the real-time 
monitoring tool but I couldn't tell if the PRIs were being 
oversubscribed.  We have 6 PRIs coming into 2 separate 6608s.  Then 
without warning, 3 of the sites that are on this cluster lost all dial 
tone.  We didn't even have internal dial tone.  When you lifted the 
receiver there was nothing.   Only one site was still up and they were 
homed to a different server.

We rebooted the publisher and the two subscribers that displayed the 
problem and everything started working normally.   I had no errors in 
my app log on any of the servers and it didnt show any of the phones 
come unregistered.  I am at a loss.  I have never seen anything like 
this before.

  Has anyone ever seen this?  Any ideas as to what caused it?  I didn't 
see any errors on the switchports either.
