The Lite will still have problems. It will recognize but the MICS 6.1 with a Flash 1.7 is just not a good Marriage. I know they want to save money, but on this one I say upgrade the Flash to the 1.9 or the 2.0.10 and be done with it. Good luck and if you leave the Flash at a 1.7 you will get called with issues regarding the unit not recognizing certain tones, not notifiing messages, and being busy when trying to get to mailboxes. These will of course be your fault in the eyes of the customer.
