[SR-Users] IMS and SIP over WebSocket 500/Error

Hello all, I have installed Kamailio 4.1.2 in IMS configuration (3 Kamailio instances to run in P/I/S-CSCF modes) Everything works fine with Native IMS clients (Boghe) I want now to introduce Web clients using WebSockets. I have added to the P-CSCF Kamailio.cfg the websockets parts Registration is Ok but I can't manage placing a call. With SIPoWS, the contact header is sip:olivier@132.invalid. So when the P-CSCF receives a terminating INVITE, its destination URI is sip:olivier@132.invalid , it tries to make a DNS resolution of 312.invalid and it doesn't forward to the client saying the domain is unknown and can't be routed I guess that something is missing in my configuration around aliases/nathelper/outbound but didn't find what... Thanks for any help Olivier DURECU Bell Labs / IP Platform Research Villarceaux Center Tel: +33(0) 130772759 GSM: +33(0) 683776482
