Call manager-publisher went down due to some reason and subscriber came up automaticaly .But some ip phones didnot work with the subscriber.can any body help me to find out the reason?/
Did the subscriber take full copy from the publisher
check the Synchronization between the publisher and subscriber
the subscriber did not take all updated ip phones
so, the ip phones that didnot work, they are new to it
If you only have two servers phones should register to the SUB and in case of failure failover to the PUB, not the other way around.
Do you have both servers in the CUCM group?
