Hi folks I have FreeSWITCH running behind Kamailio, which acts as a TCP (client side) to UDP (FreeSWITCH side) bridge. The client registers with a binding like: Contact: <sip:1010@192.168.1.228:32204;transport=tcp> and the Kamailio server is adding a Path header as follows: Path: <sip:10.1.1.1;lr> FreeSWITCH stores this as: Contact:<sip:1010@192.168.1.228:32204;transport=tcp;fs_path=%3Csip%3A10.1.1.1%3Blr%3E> But then when originating /bridging a call to this user, I get: [DEBUG] sofia_glue.c:2055 sip:10.1.1.1;lr;transport=tcp Setting proxy route to sofia/internal/sip:1010@192.168.1.228:32204 which indicates that the wrong transport is being used. If I add transport=udp to the Path header generated by Kamailio, the correct transport is used. However the Path URI, by not including a transport parameter, implicitly specifies UDP. Am I doing something wrong or could this possibly be a bug? Regards, Richard
