[cisco-voip] Graceful Failover between CallManagers.

[Lelio Fulgenzi]

There is no reboot required. I think if the phone itself is already connected to the backup callmanager as standy the failover is relatively quick. A quick screen refresh happens if I'm not mistaken. If it is the third CallManager that it is failing over to, it might take a little longer.

If there is an actve call, the whole process waits until that call is over.

  Can someone confirm my thinking on this.

  I have a Publisher /Subscriber setup with the phones registered to the Subscriber.

  I had thought that if the subscriber goes off line, the phones will reboot and re-register with the publisher 
  but if I shutdown the callmanager process on the subscriber the phones will re-home to the publisher without a phone reboot.

  Any thoughts?

  Scott
