Hello Enthusiasts! Ok... I've only used 1 of the apps for pre-paid system for *. The entire list is available at http://www.voip-info.org/wiki-Asterisk+Prepaid+Applications
The only one I have investigated is Asterisk 2 Billing system. My question is more of a "which one is most widely supported"... in other words... I'd like to know which pre-paid app is most common and mostly used. It's very time consuming for me to test them all... and though A2Billing does what I need, I want to keep an open mind with other apps. My ONLY requirement with pre-paid apps is to generate call cards & it's pins... so clients can access long distance through a local 416 number and they will have to enter their PIN number or a 6 to 12 digit code to gain access to long distance. The other possibility is for them to refill online. The good to have, is people will be granted long distance via their caller ID authentication. All this is possible with A2Billing, but I want to hear your experience, if anyone has deployed at least one of these apps at a production level... if not... development level deployment is also good :)... but I would like to hear your story! Cheers!
