Prime Collaboration Provision has an excellent centralized management of a set of “Business Rules” that really identify a level of system configuration that can be applied to a cluster.
In this example below (using PCP 10.6), the default Unity Connection PIN is set to a trivial value of 123456.
System-level considerations still apply! For the example of Unity Connection, one would need to modify the Authentication Rules to accommodate trivial passwords. This param is called DefaultUnitySubscriberPassword.
This is in fact also referenced in the online documentation:
The DefaultUnitySubscriberPassword rule does not validate the length of the default password entered in the data field. Cisco Unity Connection may have different credential policies configured.
Another VERY USEFUL param is LineDisplayString – great for batch provisioning off templates and avoiding messy template updates for a single cluster-wide standard!
Again, from the documentation:
Template string used to construct the Internal Caller ID display format for the phone line. If disabled, the system defaults to FIRSTNAME LASTNAME. This rule does not apply if the Service Area has a Cisco Unified Communications Manager Express as a Call Processor.
The default value for the Display (Internal Caller ID) provisioning attribute is applied from this rule. If you specify CUPM_BLANK or an empty value in batch provisioning or through the Prime Collaboration Provisioning user interface, the value for the Display (Internal Caller ID) provisioning attribute comes from this rule.
Therefore, if you want to set an empty value for the Display (Internal Caller ID) provisioning attribute, you must enable this rule and make sure its value is empty.
