I have an Expressway-C & Expressway-E pair in both my primary & secondary data centers for MRA.
My Public SRV record for collab-edge has a priority 1 for the primary data center & priority 5 for the secondary data center.
If my primary DC goes down, phones automatically register to the secondary DC expressways without issue.
This issue is when the primary DC comes back online the MRA phones still stay registered to the secondary DC.
Is there a timer that can help/control the failback process?
Thanks
Frank
