[cisco-voip] IM&P, Jabber, Presence Redundancy Groups, Assigned Presence Server

[daniel at ohnesorge.me]

Hi Anthony,

I dare say that the CUPS BU did not give user assignment much thought with regards to geographical regions. 

What I would do in this instance (and may or may not be possible for you to re-design) is to have separate clusters for your East Coast and West Coast. This would be achieved by changing the LDAP to point 1 cluster to a more specific geographical OU. 

For CUCM you can easily set up ILS/GDPR to exchange your extensions between cluster and EMCC (Extension Mobility Cross Cluster) is fairy trivial. This setup would also support centralised TFTP for phone registration and centralised Jabber login. Now when it comes to CUPS, you will of course be using Inter-cluster Peering. The downside to this for both CUCM and CUPS, there is no redundancy between East Coast and West Coast (between your DC's) but this can still be achieved with subscribers in each DC.

Otherwise, I'd just assign users to Service Profiles by way of Feature Group Templates assigned to different LDAP Directory sync agreements.

I'm not excited about that method, unless one of you calms my fears.

I.e., Your process to assign users, both existing in the system today, and newly synced from LDAP, to their geographic IM&P nodes and therefore Presence Redundancy Groups?  I'm not quite looking for a SQL query method, or an AXL method, something a operations person could manage through the GUI.
