LINECALLPARAMFLAGS_ Constants

The LINECALLPARAMFLAGS_ constants describe various status flags about a call.

LINECALLPARAMFLAGS_BLOCKID

LINECALLPARAMFLAGS_DESTOFFHOOK

LINECALLPARAMFLAGS_IDLE

The call should be originated on an idle call appearance and not join a call in progress. When using the lineMakeCall function, if the LINECALLPARAMFLAGS_IDLE value is not set and there is an existing call on the line, the function breaks into the existing call if necessary to make the new call. If there is no existing call, the function makes the new call as specified.

LINECALLPARAMFLAGS_NOHOLDCONFERENCE

This bit is used only in conjunction with lineSetupConference and linePrepareAddToConference. The address to be conferenced with the current call is specified in the TargetAddress member in LINECALLPARAMS. The consultation call does not physically draw dial tone from the switch, but will progress through various call establishment states (for example, dialing, proceeding). When the consultation call reaches the connected state, the conference is automatically established; the original call, which had remained in the connected state, enters the conferenced state; the consultation call enters the conferenced state; the hConfCall enters the connected state. If the consultation call fails (enters the disconnected state followed by idle), the hConfCall also enters the idle state, and the original call (which may have been an existing conference, in the case of linePrepareAddToConference) remains in the connected state. The original party (or parties) never perceive the call has having gone onhold. This feature is often used to add a supervisor to an ACD agent call when necessary to monitor interactions with an irate caller.

LINECALLPARAMFLAGS_ONESTEPTRANSFER

This bit is used only in conjunction with lineSetupTransfer. It combines the operation of lineSetupTransfer followed by lineDial on the consultation call into a single step. The address to be dialed is specified in the TargetAddress member in LINECALLPARAMS. The original call is placed in onholdpendingtransfer state, just as if lineSetupTransfer were called normally, and the consultation call is established normally. The application must still call lineCompleteTransfer to effect the transfer. This feature is often used when invoking a transfer from a server over a third-party call control link, because such links frequently do not support the normal two-step process.

LINECALLPARAMFLAGS_ORIGOFFHOOK

LINECALLPARAMFLAGS_PREDICTIVEDIAL

This bit is used only when placing a call on an address with predictive dialing capability (LINEADDRCAPFLAGS_PREDICTIVEDIALER is on in the dwAddrCapFlags member in LINEADDRESSCAPS). The bit must be on to enable the enhanced call progress and/or media device monitoring capabilities of the device. If this bit is not on, the call will be placed without enhanced call progress or media type monitoring, and no automatic transfer will be initiated based on call state.

LINECALLPARAMFLAGS_SECURE

Remarks

No extensibility. All 32 bits are reserved.
