[cisco-voip] CUCM Cluster Redundancy

[Brian Meade]

Ahmed,

I don't think this is a good route to go.  Really you should have no
dependence on the publisher besides configuration updates so it shouldn't
be anything that affects operation.

I would be concerned that the subscribers would have a more updated version
of the database than the cold-standby publisher.
