# Retrieving call information

Invoke the following functions to obtain status information on a call:

Function | Description
nccGetCallStatus | NCC_CALL_STATUS structure containing information about the call, such as the DID and ANI information, or the current call state.
nccGetExtendedCallStatus | NCC_ISDN_EXT_CALL_STATUS structure containing protocol-specific information about the call.

You can invoke either of these synchronous functions in any call state, as long as the line is in active line state.
