Article
10/13/2021

The EnumerateCallingCards method enumerates calling cards associated with the address. This method is provided for C and C++ applications. Automation client applications, such as those written in Visual Basic, must use the get_CallingCards method.

Syntax

HRESULT EnumerateCallingCards(
  [out] IEnumCallingCard **ppEnumCallingCard
);

Parameters

[out] ppEnumCallingCard

Pointer to IEnumCallingCard interface.

Return value

This method can return one of these values.

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

Remarks

This method is a COM wrapper for the TAPI 2.1 LineGetTranslateCaps function, and takes calling card information from the LINETRANSLATECAPS structure returned by that function.

TAPI calls the AddRef method on the IEnumCallingCard interface returned by ITAddressTranslation::EnumerateCallingCards. The application must call Release on the IEnumCallingCard interface to free resources associated with it.
