Article
02/22/2024

The get_CallHubs method creates a collection of the currently available call hubs. Provided for Automation client applications, such as those written in Visual Basic. C and C++ applications must use the EnumerateCallHubs method.

Syntax

HRESULT get_CallHubs(
  [out] VARIANT *pVariant
);

Parameters

[out] pVariant

Pointer to VARIANT containing an ITCollection of ITCallHub interface pointers (CallHub objects).

Return value

This method can return one of these values.

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

Remarks

TAPI calls the Addref method on the ITCallHub interface returned by ITTAPI::get_CallHubs. The application must call Release on the ITCallHub interface to free resources associated with it.
