TSPI_lineRemoveFromConference

The TSPI_lineRemoveFromConference function removes the specified call from the conference call to which it currently belongs. The remaining calls in the conference call are unaffected.

LONG TSPIAPI TSPI_lineRemoveFromConference(
DRV_REQUESTID dwRequestID,  
HDRVCALL hdCall );

Parameters

  • dwRequestID
    The identifier of the asynchronous request.
  • hdCall
    The handle to the call to be removed from the conference. The call state of hdCall can be conferenced.

Return Values

Returns dwRequestID, or an error number if an error occurs. The lResult actual parameter of the corresponding ASYNC_COMPLETION is zero if the function succeeds, or an error number if an error occurs. Possible return values are as follows:

LINEERR_INVALCALLHANDLE, LINEERR_OPERATIONUNAVAIL, LINEERR_INVALCALLSTATE, LINEERR_OPERATIONFAILED, LINEERR_NOMEM, LINEERR_RESOURCEUNAVAIL.

Remarks

This operation removes a party that currently belongs to a conference call. After the call has been successfully removed, it may be possible to further manipulate it using its handle. The availability of this operation and its result are likely to be limited in many implementations. For example, in many implementations, only the most recently added party can be removed from a conference, and the removed call may be automatically dropped (becomes idle). The service provider indicates its capabilities in LINEDEVCAPS with regard to the available effects of removing a call from a conference.

If the removal of a participant from a conference is supported, the service provider must indicate in the dwRemoveFromConfState member in LINEADDRESSCAPS the call state to which the call transitions after it is removed from the conference.
