Hi all, I advanced in my LAB I have this configuration: 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)
When I received the reinvite from "rest of infra" on private interface (10.1.15.126), I could see this log: Dec 16 12:55:27 am-frontal1a-test /usr/local/sbin/opensips[26160]: ERROR:tm:msg_send: send() to 192.168.10.203:5060 for proto tcp/2 failed Dec 16 12:55:27 am-frontal1a-test /usr/local/sbin/opensips[26160]: ERROR:tm:t_forward_nonack: sending request failed Dec 16 12:55:27 am-frontal1a-test /usr/local/sbin/opensips[26160]: retcode = -6 I don't know why OpenSIPS tries to send the Re-invite to client private IP instead client public port and IP (natted). Do you have an idea please ? thanks Le jeu. 12 déc. 2019 à 11:09, Mickael Hubert <[email protected]> a écrit : > Hi all, > I have an issue, opensips doesn't want forward Re-INVITE during UDP to TCP > mapping session. > Customer (NATTED) -- TCP --> (public interface listen tcp:8060) OpenSIPS > (private interface listen udp:5060) --> rest of infrastructure (udp:5060) > > I can send a call from customer to OpenSIPS (initial INVITE, 200OK, etc > ...). > But when I received Re-INVITE from UAS (sip session timer), OpenSIPS > doesn't forward it to customer. > > You can see the call flow here: > https://photos.app.goo.gl/eUSb5MvBhUfueaoM7 > You can see SIP messages and opensips's logs in txt file in attachment > > OpenSIPS handles on it's public interface: > - Topology hiding > - Nat detection > > Thanks a lot for you help ! > >
