This involves an sx-50 in a lodging situation...

I understand it is possible to program the system to automatically dial the second 9 (for example if a person dials 9 to grab an outside line, then dials xxx-xxxx, the system would send 9xxx-xxxx so that the call would go out).

The question is this, can I make it so the room phones append the 9 and the console and other office phones do not (so they can do the 4-digit transfer).

Mind, I am asking if it can do it...not how...yet
