I have a 3300 which is set to send out extensions ddi if available otherwise if no ddi then another number is sent which, when rung back goes to the switchboard. Intermittently when dialling out the bearer number is sent (which, you probably guessed is the CEO's number). I have tested every phone dialling out and they all send the correct number, except that twice the bearer number was sent, but dialling again from the same phone sent the correct ddi.
