In a typical Cisco collaboration network, there can be multiple possibilities from campus to remote sites. Figure 2-1 gives an overview of a typical large enterprise Cisco collaboration campus network where the Cisco collaboration services are available in the campus (headquarters) network.

As discussed previously, the collaboration network and the associated collaboration services vary from one organization to another. Some of the factors considered are:
Number of branch or remote sites
Call control configuration (centralized/distributed)
Services available for branch or remote sites
The following sections cover CUCM deployment models to support various organization/network/service requirements.
