The 4 subscribers in the cluster has gone down, and about 2000 IP phones connected to this
CM are down.
To add,there is no link issue,no hardware issue.CCM service restart did not help us,then restarted physically all the four subscribers and found all the IP Phones are registering back with the respective subscribers.
Cpuld you pls share your ideas on this issue.
Looking forward to hear from you guys..
