|Using Voice Features / Communicating with Multiple Sites|
If your installation supports multiple sites, you can communicate with other users, groups, and address book entries at your local site as well as at any other site.
When you roam from site to site, the Vocera server knows which site you are visiting and can direct calls to your device there.
Groups, locations, and address book entries at different sites can have the same name. For example, each site can have its own “Code Blue” group, its own “Cafeteria” location, and its own “The Local Pharmacy” address book entry.
Each site in your organization has a unique name. For example, you may have site names such as New York, Philadelphia, and Washington, or even site names such as Third Street or North Wing.
