So what is the function of ITAddress->GetAddressName(BSTR ppName)?
that is the functon I have been using,

Ok, i think am getting the TAPI and VC++ now,
I would like to output the device name to the console..
but for some reason i only get the mem address or hex
am using pAddress->AddressNam(&ppName)
when I try to output ppName, I get hex or address location
imhotep,
please note that dwAddressOffset is: "Offset from the beginning of the
structure to the variably sized address field. The size of the field is
specified by dwAddressSize."
So to access the string you need to do some pointer arithmetics and type
castings:
LONG lRet = lineGetAddressCaps(,,,,,lpAddressCaps);
// check return code and process possible errors
// check if (lpAddressCaps->dwTotalSize < lpAddressCaps->dwNeededSize) and
reallcoate more memory for lpAddressCaps before retrying
lineGetAddressCaps()
char* sAddress =
(char*)(((BYTE*)lpAddressCaps)+lpAddressCaps->dwAddressOffset);
// when using sAddress it is strongly recommended to access it only upto its
valid length: lpAddressCaps->dwAddressSize bytes.
