How do I dial a prefix on a Brother fax-machine?

With our fax machine you can’t set it up globally like that. Our solution, that should work for you is to set your access code on a speed dial number.

So on a Brother machine, I think you can do it one of two ways, either with a quick touch button or a speed dial number. Basically set quick touch button 1 to ”*99”. Then when you go to send something, hit button 1 then dial the number and click start.
