is there a way to batch import users in a CMA addressbook? Let's say i have a list of 500 users...
there is no way to batch import users into CMA, only Resource Manager supports it.
you can integrate with CMA address book and it will import the Global address book from CMA dynamically. you can find the integration steps in the RMX admin guide section "Integrating the Polycom CMA™ Address Book with the RMX"
