# Closing Natural Access services

Natural Access supports opening and closing services on a context as needed during an application's execution. An application can free system resources it no longer needs to optimize performance.

Use ctaCloseServices to close the NaturalFax services. ctaCloseServices destroys any open document queues associated with the service on the specified context. ctaCloseServices does not release the call, nor does it close the ADI service unless specified.
