Hello, when I connect to Kamailio over websocket, according to the websocket protocol K. sends “HTTP/1.1 101 Switching Protocols” and K. logs: 17(18) DEBUG: websocket [ws_handshake.c:179]: ws_handle_handshake(): found Upgrade: websocket 17(18) DEBUG: websocket [ws_conn.c:195]: wsconn_add(): connection id [14] 17(18) DEBUG: websocket [ws_conn.c:213]: wsconn_add(): new wsc => [0x7fcad6e10160], ref => [0] 17(18) DEBUG: websocket [ws_conn.c:233]: wsconn_add(): added to conn_table wsc => [0x7fcad6e10160], ref => [1] 17(18) DEBUG: sl [sl.c:310]: send_reply(): reply in stateless mode (sl) 17(18) DEBUG: <core> [core/msg_translator.c:162]: check_via_address(): (22.222.222.222, 22.222.222.222, 0) 17(18) DEBUG: <core> [core/tcp_main.c:1644]: _tcpconn_find(): found connection by id: 14 17(18) DEBUG: <core> [core/tcp_main.c:2528]: tcpconn_send_put(): send from reader (18 (17)), reusing fd 17(18) DEBUG: <core> [core/tcp_main.c:2763]: tcpconn_do_send(): sending... 17(18) DEBUG: <core> [core/tcp_main.c:2796]: tcpconn_do_send(): after real write: c= 0x7fcad6da7b38 n=238 fd=9 17(18) DEBUG: <core> [core/tcp_main.c:2797]: tcpconn_do_send(): buf= 17(18) DEBUG: <core> [core/parser/parse_fline.c:255]: parse_first_line(): bad request first line 17(18) DEBUG: <core> [core/parser/parse_fline.c:258]: parse_first_line(): at line 0 char 22: 17(18) DEBUG: <core> [core/parser/parse_fline.c:264]: parse_first_line(): parsed so far: HTTP/1.1 101 Switching 17(18) ERROR: <core> [core/parser/parse_fline.c:271]: parse_first_line(): parse_first_line: bad message (offset: 22) 17(18) DEBUG: <core> [core/parser/msg_parser.c:675]: parse_msg(): invalid message 17(18) ERROR: <core> [core/parser/msg_parser.c:749]: parse_msg(): ERROR: parse_msg: message=<HTTP/1.1 101 Switching Protocols Sia: SIP/2.0/TLS 22.222.222.222:33776 Sec-WebSocket-Protocol: sip Upgrade: websocket Connection: upgrade Sec-WebSocket-Accept: NeswoJX5ZQp7ER8hTKM5B3a3HDQ= Content-Length: 0 17(18) ERROR: <core> [core/msg_translator.c:3256]: build_sip_msg_from_buf(): parsing failed 17(18) DEBUG: app_lua [app_lua_api.c:1924]: sr_kemi_lua_exit(): script exit call 17(18) DEBUG: app_lua [app_lua_api.c:789]: app_lua_run_ex(): ksr error call from Lua: ~~ksr~exit~~ 17(18) DEBUG: app_lua [app_lua_mod.c:164]: sr_kemi_config_engine_lua(): execution of route type 513 with name [ksr_xhttp_event] returned 1 22.222.222.222 is my public address (the address of my router). It is not the IP-address of Kamailio. While the returned address is not parseable in terms of SIP, it is a valid Websocket-answer message. This valid condition triggers logging an error, but does not represent an error condition. How can I avoid that the above non-error is logged as an error? Thanks for your feedback Дилян
