Cisco Unified Communications Systems Release 7.0(1) testing was designed to test the hardware and software components that work together in a multisite distributed deployment. For this testing, several site models were created. Each site model was designed to test a specific set of features and interactions. For information about the components, configurations, and environment tested in this Cisco Unified Communications Release, see Table 1.

Table 1 Tested Deployment and Site Models 

Deployment Model
Description

Single-Site Model Opens new window

This model is designed for autonomous offices in which most or all employees are IPC users. This model can support up to 30,000 users.

Multisite Centralized Call Processing Model Opens new window

This model is designed for distributed operations with a large central or headquarters site and multiple remote or branch sites. This model can support up to a total of 30,000 phones distributed among up to a maximum of 1000 sites. Based upon the bandwidth available, each site can support any number of users up to the overall total of 30,000 phones.

Multisite Distributed Call Processing Model Opens new window

This model is designed for organizations with large user populations or large numbers of geographically distributed sites resulting in the need for more than a single call processing entity. This model is suited for deployments that require multiple Cisco Unified Communications Manager clusters or Cisco Unified Communications Manager Express platforms. Each call processing entity in this model is configured as a Single-Site Model or Multisite Centralized Call Processing Model and each has a common dial plan and feature set.

Clustering Over IP WAN Call Processing Model Opens new window

This model is designed for organizations with large user populations across multiple sites that are connected by an IP WAN with the QoS features enabled. It supports the Local Failover Deployment Model and the Remote Failover Deployment Model.
