For the most part installing the subscriber is pretty self explanatory. You want to make sure that you are installing only 1 subscriber at a time due to the necessity of the DB replication. When we installed our second subscriber we made sure that the version installed was exactly the same as the production versions. I am not sure if this is necessary but it was comforting for us to do it this way. I have pasted below our services that are running on both our publisher and subscriber servers for your reference. These can be found through the serviceability web management interface.
I have activated the services similar to that of yours.And after that the subscriber server's database got updated.
But when i remove the publisher from network, my subscriber server is not becoming active. All IP Phones give the message " Opening 10.81.0.1" (Ip address of Publisher server). I have configured subscriber server in CallManager group and the IP phones show my subscriber server as CallManager 2 in Network Configuration option.
Warning. The action below will cause ALL registered devices to reset.
The answer to your question is on the CallManager Group Configuration page (off CCMAdmin web page). Move the secondary subscriber-server to the top.
So when you wrote that you removed the pub from the network, I hope you mean that you were just testing it. The pub maintains the database - the sub has a read-only database.
All ccm servers in the cluster have to be rebooted after adding the secondary server. It worrisome that your phones did not register to the sub server even if it is the second on the list after the pub had been removed from network.
