you can have only one call manager Publisher in a CLUSTER.

Hi

+5 for Aman .  The publisher is a required server in all clusters, there can be only one publisher per cluster. This server is the first to be installed and provides the database services to all other subscribers in the cluster. The publisher server is the only server that has full read and write access to the configuration database . The Subscribers are responsible for Call processing , you can also use TFTP server , and other server for MOH. Only one publisher for one cluster.
