Thanks for your help David, I'm already in debug level: log_level=4 UAC is not in location table, because it's IP2IP connection (without registration)
I did another test: I try to activate "Pp" in dialog creation to send OPTIONS to both sides (leg A and B) SIP client (tcp:192.168.10.203) -- my NAT router --> (tcp:2.2.2.2:8060) opensips (udp:10.1.15.126:5060) --> rest of infra (udp:10.1.15.0/24:5060) OPTIONS from private interface is sent, but OPTIONS from public interface can't be sent to natted UAC: Dec 16 16:52:22 am-frontal1a-test /usr/local/sbin/opensips[2705]: ERROR:tm:msg_send: send() to 192.168.10.203:5060 for proto tcp/2 failed Dec 16 16:52:22 am-frontal1a-test /usr/local/sbin/opensips[2705]: ERROR:tm:t_uac: attempt to send to 'sip:192.168.10.203;transport=tcp;r2=on;lr;did=d9.ed83b676' failed Dec 16 16:52:43 am-frontal1a-test /usr/local/sbin/opensips[2693]: ERROR:tm:msg_send: send() to 192.168.10.203:5060 for proto tcp/2 failed Dec 16 16:52:43 am-frontal1a-test /usr/local/sbin/opensips[2693]: ERROR:tm:t_uac: attempt to send to 'sip:192.168.10.203;transport=tcp;r2=on;lr;did=d9.ed83b676' failed My other test (into VPN) works like a charm, but UAC is registered ! Is there a way to keep natted source ip and port to reuse them with initial request from UAS ? I use topology_hiding function, and it's not compatible with record_route. But I tested to deactive TH and active RR, it's exactly the same issue, the Re-INVITE from UAS is not forwarded to UAC. thanks Le lun. 16 déc. 2019 à 15:52, David Villasmil < [email protected]> a écrit : > please increase the debug level and paste the log.
