Hi just wondering how we scale beyond 10000 users for CUPs.
The SRND states that - 'CUP Cluster Supports Only Single CUCM cluster'
So if I need 20000 presence users then I would need 2 CUPs clusters integrated to the single CUCM cluster ? Is that Correct? (I hope its not the case that I require 2 CUCM clusters!)...TIA, Jeff
