[cisco-voip] 7970 phones not failing over in CCM 4.1.2

Tue Mar 8 08:34:36 EST 2005

You mentioned that the phone never registers with the other servers,  
but then you say you have both servers configured in option 150 from  
DHCP.

So, is the problem that it never hits the backup TFTP server or that it  
never attempts to register with the subscriber?  Even when the primary  
server is up the phone *should* keep a TCP session up with the backup  
server on TCP 2000.  It will send keepalives to the backup server, but  
it doesn't expect a keepaliveAck except from the server it's currently  
registered with.

For the TFTP issue did you add both servers as TFTP servers when you  
ran the CTL plugin?  Remember that an authenticated phone will only  
connect to a TFTP server listed in the CTL file.

I'm thinking it's a bug too; I don't see why others aren't seeing it
though given the fact that it's awfully serious.  :-(!!

THANKS!!!!!! for your pointers.  I'm getting the distinct feeling it's  
got
something to do with the certificate stuff; unfortunately that's a key
component that our Security guys are worried about.  Rock>me<hard_place.
