The process of reserving an extension is done when defining extensions. In Figure 18 the user Mary Johnson will have a reserved extension in the Manager department. Mary Johnson can be identified in the var_Location parameter in the Zebra Voice Client XML file or by leveraging the credentials passed through a connection to the customer’s identity management.
If the customer administrator uses the WFConnect.xml client configuration file, the var_location parameter displays, as shown in Figure 19.
