Hi there, we have been on the calling card business for a while now, we started using Windows and SQL based billings, etc, we migrated onto a2b and love it. It works smoothly and has great features.
I need to have the info of PIN activation, expiration, etc, aswell as campaigns info. We offer promotional calling card campains, so all this info would be nice.
Other feature that i found very interesting on other billing was: when a customer dials "1" after pin number, their caller id is inserted onto their account and becomes pinnless, loved that feature!
we arent that experienced so we cant develop these....
We are very interested on contributing with A2B, if someone can develop this feature, we would be glad to pay for it and release it onto all A2B community (for free obviously)
We use A2B for business and i think its fair to contribute anyway we can with the A2B project.
