Dear OpenSIPS users,
According to the OpenSIPS log, a callee answered a caller with SIP OK. Such SIP OK has the following contact: Contact: "Group" <sip:g1r2u3p4o5@127.0.0.1:40348;transport=TLS;ob>;+sip.ice However, it seems that there is no available connection to port 40348. That is, opensips cann't send any message to that port. So, after opensips relaying a SIP ACK to g1r2u3p4o5, it caused the following error: Jan 09 17:48:54 colibri-imx6 opensips[23115]: Jan 9 17:48:54 [23135] INFO:core:probe_max_sock_buff: using snd buffer of 320 kb Jan 09 17:48:54 colibri-imx6 opensips[23115]: Jan 9 17:48:54 [23135] INFO:core:init_sock_keepalive: TCP keepalive enabled on socket 22 Jan 09 17:48:54 colibri-imx6 opensips[23115]: Jan 9 17:48:54 [23135] ERROR:core:tcp_connect_blocking: poll error: flags 28 - 4 8 16 32 Jan 09 17:48:55 colibri-imx6 opensips[23115]: Jan 9 17:48:54 [23135] ERROR:core:tcp_connect_blocking: failed to retrieve SO_ERROR [server=127.0.0.1:40348] (111) Connection refused Jan 09 17:48:55 colibri-imx6 opensips[23115]: Jan 9 17:48:54 [23135] ERROR:proto_tls:tls_sync_connect: tcp_blocking_connect failed Jan 09 17:48:55 colibri-imx6 opensips[23115]: Jan 9 17:48:54 [23135] ERROR:proto_tls:proto_tls_send: connect failed Jan 09 17:48:55 colibri-imx6 opensips[23115]: Jan 9 17:48:54 [23135] ERROR:core:msg_send: send() for proto 3 failed What is happening here? How can a peer lost its connection or lost connect to opensips? How to avoid this issue or recover from it? I have no idea on what to do. Any hint will be very helpful! Thanks a lot.
