I came cross to talkra.com where Eric started one page to discuss about revenue assurance open source code. This is good but the questions here is why we need open source for revenue assurance? (Before we start asking what is RA open source, it's better to know why we want to do open source). What are the advantage of RA open source compare to Subex, WeDo, Connectiva or the rest RA vendor? What can they offer and can’t offer by open source community?
