Platform SDK: TAPI

ITMSPAddress::CreateMSPCall

The CreateMSPCallCreate method creates an MSP Call object. TAPI aggregates this onto the main Call Object and exposes the ITStreamControl interface.

HRESULT CreateMSPCall(
  MSP_HANDLE hCall,
  DWORD dwReserved,
  DWORD dwMediaType,
  IUnknown *pOuterUnknown,
  IUnknown **ppStreamControl
);

Parameters

hCall: [in] Handle for this MSP.
dwReserved: [in] Reserved value – will be 0.
dwMediaType: [in] Indicates media types required for the call.
pOuterUnknown: [in] The pointer to the IUnknown interface on the TAPI 3.0 call object. Since the MSP Call object is aggregated in the TAPI 3.0 call object, it needs to know the outer IUnknown.
ppStreamControl: [out] Pointer to IUnknown interface pointer of ITStreamControl interface for newly created call.
