/**
 * Encapsulated gateway address information for outgoing call. When calls are made, the system
 * provides a facility to specify two addresses for the call: one to display as the address being
 * dialed and a separate (gateway) address to actually dial. Telecom provides this information to
 * {@link ConnectionService}s when placing the call as an instance of {@code GatewayInfo}.
 * 
 * The data consists of an address to call, an address to display and the package name of the
 * service. This data is used in two ways:
 * 

 *  Call the appropriate gateway address.
 * 
 Display information about how the call is being routed to the user.
