/mcpCisco TSP includes DND feature support for TAPI applications that negotiate at least extension version 8.0 (0x00080000). Applications can only enable or disable the DND feature on a device. Cisco TSP allows TAPI applications to enable or disable the DND feature via the lineDevSpecificFeature API. Cisco TSP notifies applications via the LINE_DEVSPECIFICFEATURE message about changes in the DND configuration or status. To receive change notifications, an application must enable the DEVSPECIFIC_DONOTDISTURB_CHANGED message flag with a lineDevSpecific SLDST_SET_STATUS_MESSAGES request. This feature applies to phones and CTI ports. It does not apply to route points. Do Not Disturb-Reject Do Not Disturb (DND) enhancements support the rejection of a call. The enhancement Do Not Disturb–Reject (DND–R) enables the user to reject any calls when necessary. Prior to the Unified Communications Manager Release 7.0(1), DND was available only with the Ringer Off option. If DND was set, the call would still get presented but without ringing the phone. To enable DND–R, access the Unified Communications Manager Administration phone page or the user can enable it on the phone. However, if the call has an emergency priority set, the incoming call is presented on the phone even if the DND–R option is selected. This will make sure that emergency calls are not missed. Feature priority is introduced and defined in the enum type for making calls or redirecting existing calls. The priority is defined as: enum CiscoDoNotDisturbFeaturePriority { CallPriority_NORMAL = 1 CallPriority_URGENT = 2 CallPriority_EMERGENCY = 3 }; Feature priority introduces LineMakeCall as part of DevSpecific data. Currently the following structure is supported in DevSpecific data for LineMakeCall: typedef struct LineParams { DWORD FeaturePriority; } LINE_PARAMS; The new Cisco LineDevSpecific extension, CciscoLineRedirectWithFeaturePriority with type SLDST_REDIRECT_WITH_FEATURE_PRIORITY, supports redirected calls with feature priority. Also in a shared line scenario, if one of the lines is DND–R enabled and if the Remote In Use is true, then it will be marked as connected inactive. Interface Changes See lineMakeCall, on page 177 and Redirect with Feature Priority, on page 373. Message Sequences See Do Not Disturb-Reject, on page 664.
