the solution is found, the root of the issue was in our proxy daemon, that received sip from outside world, and proxy it to kamailio (kamailio received sip via localhost)
My ws users, have such received in location: Received:: sip:127.0.0.1:36986;transport=ws I added in NOTIFY construction (with some conditions, but the focus is here): $uac_req(ouri) = "sip:127.0.0.1:" + $sp + ";transport=ws"; and this helped (kamailio send to proxy daemon via localhost, which when receive on exact port, nows where to send it outside) issue is no more relevant cheers -- View this message in context: http://sip-router.1086192.n5.nabble.com/issue-with-uac-req-send-to-websocket-peer-tp142954p142969.html Sent from the Users mailing list archive at Nabble.com. _______________________________________________ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users@lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users
