I'm new to BCM50 setup and my company would like to setup a demo for the BCM50 as we are being certified as an installer/seller. What is the best way to set the system up to show the phones and features but not replacing or using the phone lines in the company as we still have a reliable system in place. I have BCM50 1.0, 1230 IP phone, T7316 Std. phone, and a T7406E cordless phone. I have all the keycodes available to initialize the BCM's features but don't want to do anything without knowing I can in fact do a good display.
