Hi all, If you want to see a full-blown Kamailio v3.1.3 based open-source VoIP system in action, check our latest sip:provider CE v2.2-rc1, which has been released today: http://www.sipwise.com/news/announcements/spce-v2_2rc1-release/ It leverages the capabilities of Kamailio to build a quite complex SIP routing engine using a SIP load-balancer and a SIP proxy/registrar, as well as SEMS acting as b2bua. On top of it, it provides provisioning and billing modules and admin and user web interfaces to form an out-of-the-box VoIP soft-switch. Feedback is very much appreciated. Andreas
