ITBasicCallControl::Conference

The conference method adds a consultation call to the conference in which the current call is a participant. If an associated ITCallHub object does not exist, it is created.

HRESULT Conference(
  ITBasicCallControl *pCall,
  VARIANT_BOOL fSync
);

Parameters

pCall: [in] Pointer to the ITBasicCallControl interface for the consultation call.
fSync: [in] Indicates whether the call should be conferenced synchronously (VARIANT_TRUE) or asynchronously (VARIANT_FALSE). See Connect for additional explanation.

Return Values

S_OK	Method succeeded.
E_OUTOFMEMORY	Insufficient memory exists to perform the operation.
E_POINTER	The pCall parameter is not a valid pointer.
E_INVALIDARG	The pCall parameter does not point to a valid interface.
TAPI_E_TIMEOUT	The operation failed because the TAPI 3.0 DLL timed it out. The timeout interval is two minutes.
