/mcpgetCurrentCallingDisplayNamePI() Returns the PI that is associated with getCurrentCallingDisplayNamePI. If it returns true, the application displays the address name. If it returns false, the application must not display the address name. boolean getLastRedirectingAddressPI() Returns the PI that is associated with getLastRedirectingAddressPI. If it returns true, the application displays the address name. If it returns false, the application must not display the address name. boolean The following interface on CiscoConnection retrieves the PI value for the address that is associated with the connection: CiscoConnection getAddressPI() Returns the PI that is associated with the address on which the connection gets created. If it returns true, the application displays the address name. If it returns false, the application must not display the address name. boolean No change exist in the message flow. Privacy On Hold This feature enhances the privacy of private held calls. When privacy is enabled, only the phone that placed a call on hold can retrieve that call, and the calling name and number are not displayed. The feature provides the ability for a shared address to determine whether other shared addresses may barge into a call. When privacy is enabled, other shared address cannot barge into the call. Privacy is a terminals property. On IP phones, a Privacy feature button allows the users to enable and disable the privacy feature. Privacy can be dynamically enabled and disabled for the active calls on the terminal. When Privacy is on for a call, the TerminalConnection state available to other shared addresses is set to In Use. If Privacy status is changed during the CallProgress, CiscoTermConnPrivacyChangedEvent is delivered to the application. In prior releases, if Privacy is enabled and the call is put on hold, all TerminalConnections were in TermConnHeld state and any other shared Address terminalConnection could unhold the call. In Cisco Unified Communications Manager 4.2, if the Enforce Privacy on Held Calls service parameter is enabled, and if Privacy is enabled for a call, putting the call on hold does not change the terminalConnections of other shared addresses and they remain in the In Use state. Performance and Scalability There is no performance impact with this feature because there is no additional traffic generated between Cisco Unified JTAPI, applications, and Cisco Unified Communications Manager.
