Article
02/22/2024

The get_Calls method creates a collection of calls currently active on the address. This method is provided for Automation client applications, such as those written in Visual Basic. C and C++ applications must use the EnumerateCalls method.

Syntax

HRESULT get_Calls(
  [out] VARIANT *pVariant
);

Parameters

[out] pVariant

Pointer to a VARIANT containing an ITCollection of ITCallInfo interface pointers (call objects).

Return value

This method can return one of these values.

Value	Meaning
S_OK	Method succeeded.
E_POINTER	The pVariant parameter is not a valid pointer.
E_OUTOFMEMORY	Insufficient memory exists to perform the operation.

Remarks

TAPI calls the AddRef method on the ITCallInfo interface returned by ITAddress::get_Calls. The application must call Release on the ITCallInfo interface to free resources associated with it.
