This product does exactly what it says - so far as I can see! It integrates very well with our system (AD) without any problems. We are using this to send messages from mobile devices back into AD for authentication purposes. There is nothing about this software I dislike at all. If you're looking for something easy to use, secure, and cheap; look no further than this program. The benefits include being able to communicate between users within a facility or across facilities/organizations quickly and easily.
