My coop has a front door keypad entry system for all residents. When the two digit number is pressed at the keypad, my Evo rings. Then I am supposed to be able to let the person in by pressing "9" on the EVO. But that does not work. The person who programs the buzzer system is stumped. We called Sprint and they had no answer and said it is possible the EVO cannot be used with this system to let someone in by pressing "9". Anyone know of how to rectify this?
