Just a few years ago long distance VoIP calls seemed like a great idea for the future. Well, the future came earlier than expected so more and more carriers had the need to have a unified and easy-to-use solution to offer to their clients. And Speedflow duly delivered, introducing CallMax Calling Card.
Forget about expensive physical equipment and dealing with payment gateways. CallMax Calling Card has it all! From the interactive voice responses, callbacks, all the way to bulk users and top-up codes generation. The platform supports multiple types of authorization - PIN, ANI, IP, SIP. No need to integrate third party billing modules too - our solution comes with an in-built one that perfectly complements all its functionalities.
