We will be working on Cisco UCCX 7 with High Availability model. This UCCX solution would work with CUCM cluster comprising of a Publisher and Subscriber.
When we add the RmCm Provider, do both the CUCM servers in the cluster get added, which will be used for as the redundant CTI managers?
Thanks in advance.
If the link is down for less than the retention period (default is 4 days), then the UCCX-SUB will be synchronized automatically without any intervention.
If it's more than retention period then the UCCX SUB has to be manually "reinitialized" preferably at off peak hours.
As for the election process, well it's smooth in the fact that you don't need to do anything manually. But the problem will be that some services will be in the master state on the 1st server while the other services will be in the master state on the second UCCX. (So you will have the master services split on both servers). I don't know the impact of that but i've always made sure that all of the master services are on the 1st UCCX (You can do that by restarting the 2nd server and if that doesn't work then simply shut it down and then boot it up after making sure the 1st UCCX has all master services)
PS: if the servers don't see each other in 2 ms then they are considered as disconnected from the other and will go to island mode (both will be masters until they see each other again).
