Using this setting you enable or disable the work-around for the case that the provider transmits the complete destination number (switchboard number + extension) not in the Request line but in the TO-URI, and the number in the "To" field is not necessarily longer than the number in the Request line. You should leave this setting enabled to ensure compatibility with these providers.
