Yes, this is possible, as long as your billing system supports the Radius protocol with Cisco VSA and Sterman’s extensions for SIP. However, this would probably require some modifications to your system, since PortaSIP relies on the billing system to provide AAA and call routing logic. We can provide you with information about the format of Radius exchange between PortaSIP and PortaBilling100, but you will have to do the integration work fully on your own.

You may purchase professional services from PortaOne if you need some debugging/development help. In our experience, it is probably less expensive to use PortaBilling100, rather than spend 2-6 months on integrating, testing, and debugging.
