Hello to all, what do you recommend me to evaluate as a (preferable) open source prepaid/postpaid platform based on asterisk?, ideally this should work like a gateway, i mean we have our main switch, i need to offer residencial prepaid or control to my customers because our switch doesnt support that, we just redirect the call to the prepaid platform, and if the amound is enough the call pass, if not the call drops with a message, there should be a monthly feed automatically aplied to the phone,etc.
kind regards
