Hi List,
two questions regarding Kamailio Websockets:
1. How do I send INVITE request TO the listening Websocket?
I usually used for UDP/TCP/TLS these format, but somehow this is not working for Websocket
because it gets in an endless loop:
if ($rU=~"^(\+|00|0)?[1-9][0-9]{4,20}$") {
$ru = "sip:" + $rU + "@" + $sel(cfg_get.pstn.gw_ip) +
";user=phone;transport=udp";
force_send_socket(udp:MY_EXTERN_IP:MY_EXTERN_PORT);
rtpengine_offer("internal trust-address RTP AVP");
route(RELAY);
exit;
}
2. Why do I get these errors every time my Websocket Client is registering, but it
still works and DB is inserted with registered location:
ERROR: <core> [parser/parse_fline.c:257]: parse_first_line(): parse_first_line: bad
message (offset: 22)
ERROR: <core> [parser/msg_parser.c:690]: parse_msg(): ERROR: parse_msg:

I am using Kamailio 4.3.5 + CentOS 7.2. I appreciate every help I can get.
