hTELDN

A handle to the directory number structure for the directory number on which you are setting Do Not Disturb.

dndType

The type of Do Not Disturb feature you are setting. The section "Do Not Disturb Types" (page 3-12) describes the constants to which you can set this field.

function result

A result code.

DESCRIPTION

The TELDNDSet function sets the Do Not Disturb feature for the directory number specified by the hTELDN parameter. The type of Do Not Disturb feature is specified by the dndType parameter. For example, to shut out all incoming calls, set dndType to telDNDIntExt. Note, however, that your application can provide more complex Do Not Disturb capabilities by inspecting the alerting pattern for an incoming call and rejecting unwanted calls (by calling TELReject).

To clear the Do Not Disturb feature, call the TELDNDClear function (page 3-27).
