Hi,
I have 3 sites which contain 3 CUCM Publisher on each site.
We are using Extension Mobility Cross Cluster.
Users can log in to the remote server, but sometimes there is a problem when a user cannot log in to the remote server.
The issue happens because the following configuration is missing:
CUCM server -> Advanced Features -> Cluster view, the checkbox of the remote server unchecked automatically.

I need to check it every time manually.
CUCM servers version: 12.5 SU1
Please advice.
