Deployment Recommendations
--------------------------

To prevent unexpected provisioning errors, data syncs must sync userid to
VOSS-4-UC uniquely. In other words avoid having the same userid multiple times
in VOSS-4-UC from different CUCM devices, even if at different hierarchy levels.
It is acceptable to have duplicates in different customers.

For multi-cluster call routing, the SRND recommendations around multi-cluster
deployments should still apply.  For three or more leafs, an SME cluster should be
deployed.
