Thanks to everyone on the forum, my 1a2 system is working perfectly, but now I have one more question. At my office (Noretl/Norstar System) I am used to dialing 9 for an outside line. It would be nice if I could configure my 1a2 system to require 9 for an outside line ( I know this is conuter-intuitive- pushing the outside line key gives me an outside line)

If I want to configure it such that I need to dial 9 for an outside line, what would be the easiest/cheapest way to do that ?
