Basic: Device Pools and Regions
I'm completely newbie on Collaboration. while reading the materials, I faced with a question. all of the phones are registered to a CUCM and get associated with a device pool. suppose we have a HQ site and 2 branches in which all of the telephones in the branch offices are connecting to the HQ (which holds all of the servers) through VPNs. so in this situation, do we need to create a different device pool for each site? I have created 1 Device Pool and define 3 regions and their relationships inside device pool configuration. so how can we tell a cucm to put a device inside another region?
