After redoing it about a hundred times, I think I have finally got it down pat. My voice mail announcement that is. Not too artificial, not too closeup and personal, down-to-earth and straight-forward, a message which is attractive enough to invite (potential) customers to leave their name and telephone number so that I can call them back.
Thank you for calling Gishteq, your Internet and e-business enablers. We're sorry, but there is no one available right now to handle your call. Please leave your name and telephone number after the beep, in English or in Dutch, and we will contact you right away.
