International long distance direct dialing (including INMARSAT to ships):

9 - more dial tone - 011 one to three digit country code - city code (if any) - number - 6 second pause - broken dial tone - four digit billing code

            The number of digits for overseas calls varies from 16 to 22.  The switch uses a six-second pause after your last digit as the cue that your dialing sequence is complete and then prompts you for our billing code.  After entering the billing code, it takes five to fifteen seconds before ringing is heard.  Do no confuse the overseas "double ring" with the fast busy tone.
