Learn more about Mark43"I have really enjoyed working with InterAct on our new CAD system. This system has been a wonderful improvement to our E911 Center. The technicians, trainers and customer service personnel have greatly surpassed anyone I have used in the past. The CAD system is easy to use both on the Administration and Dispatch side. I wholeheartedly recommend InterAct CAD for any agency that needs a top-of-the-line system with great customer support."
