[OpenSIPS-Users] Have one registration contact per device in usrloc

[Jayesh Nambiar]

Hi Bogdan,
So I thought of doing this and I have another problem. Say if a device
registered from IP 1.2.3.4, and then moved out to different network and
re-registered from IP 4.3.2.1, there is a stale registration lying in
opensips for the same device from 1.2.3.4.
Now when I use TCP as transport, opensips waits till connect timed out on
unreachable IPs before sending the call to registered contact and the
following messages are logged in syslog:
ERROR:core:tcp_blocking_connect: timeout 10 s elapsed from 10 s
 ERROR:core:tcpconn_connect: tcp_blocking_connect failed
 ERROR:core:tcp_send: connect failed
 ERROR:tm:msg_send: tcp_send failed

Looks like opensips tries to do a TCP connect first with all registered
contacts before actually routing the call.
I do,
modparam("registrar", "tcp_persistent_flag", "TCP_PERSISTENT")

if(is_method("REGISTER")) {
setflag(TCP_PERSISTENT);
        setbflag(30);
        if(!save("location", "fc1")) {
                t_reply("500", "Error while saving AOR");
        }
}
