Dear friends, I’m researching the freeswitch’s deploying perspective in our current infrastructure. One of the case is integration with a billing system. I have tried various modules but cannot find dynamic registration feature. And maybe Mod_xml_radius is what I need but unfortunately cannot understand how it works. Could you please help me to find out if: 1. Mod_xml_radius provides sip dynamic registration with Radius protocol. No xml files need. User database can be located in Radius server side. 2. It is possible to mix somehow radius registration with regular xml files. 3. With Mod_xml_radius is possible to apply maximum concurrent calls for the user. Thank you very much for your support, Dmitry.
