I have a customer with an older DX-80. The whole thing freaked out the other day and lost some of it's programming. I got almost all of the programming reconfigured. However the fax machine is supposed to be grabbing line 4 for out calling. I have tried to make it hotline dial to 743, but it is not recognizing other digits that are dialed after going offhook. I have also tried to adjust the delay on the hotline dial. I have also tried (using a butt set) dial #951 plus 743. And all I get is an error tone, so I belive that it is old enough firmware that that isn't an option.
