Directory Change Notification The Cisco Unified TSP sends notification events when a device has been added to or removed from the user-controlled device list in the directory. Cisco Unified TSP sends events when the user is deleted from Unified Communications Manager. Cisco Unified TSP sends a LINE_CREATE or PHONE_CREATE message when a device is added to a users control list. It sends a LINE_REMOVE or PHONE_REMOVE message when a device is removed from the user controlled list or the device is removed from database. When the system administrator deletes the current user, Cisco Unified TSP generates a LINE_CLOSE and PHONE_CLOSE message for each open line and open phone. After it does this, it sends a LINE_REMOVE and PHONE_REMOVE message for all lines and phones. Cisco Unified TSP generates PHONE_REMOVE / PHONE_CREATE messages only if the application called the phoneInitialize function earlier. The system generates a change notification if the device is added to or removed from the user by usingUnified Communications Manager or the Bulk Administration Tool (BAT). If you program against the LDAP directory, change notification does not generate. Note Do Not Disturb The Do Not Disturb (DND) feature lets phone users go into a Do Not Disturb state on the phone when they are away from their phone or simply do not want to answer incoming calls. The phone softkey DND enables and disables this feature. From the Unified Communications Manager user windows, users can select the DND option DNR (Do Not Ring). Cisco TSP makes the following phone device settings available for DND functionality: • DND Option: None/Ringer off • DND Incoming Call Alert: Beep only/flash only/disable • DND Timer: a value between 0-120 minutes. It specifies a period in minutes to remind the user that DND is active. • DND enable and disable Cisco Unified TAPI Developers Guide for Cisco Unified Communications Manager, Release 15 and SUs 54 Features Supported by TSP Directory Change Notification
