We have a cucm 6.0 cm group with 2 x servers. The phones see both servers (pub & sub)in whichever order they are in the group, but will only ever register with the CM1 (publisher). Checked all the services are running. If we make a change on the publisher, it is replicated on the subscriber. Anyone senn this, got any idea's ?
Re: Phones fail to register with cucm 6.0 subscriber
I have at least one install go south on me where the DB on the sub came out of sync. Phones would not register, MOH, etc. Ended up having to rebuild the sub completely. If you can, start up the RTMT and check the logs to see you are having DBreplication errors. If you are, this is why.
Another item to check is your CallManager Group. If you did not add the subscriber to the CUCM group, then all phones will be on the sub.

The below trick might come handy when you have to add a new node to a cluster but you don't have or is unsure of the security password for the publisher. This procedure has been around for ages.
1) Login into the CLI of the Publisher.
