My scenario :
Register Request flow
B --> opensips (tcp proxy ) --> opesips (registrar)
tcp proxy add itself in the path .. so that whenevr any request come for B that
goes through TCP proxy .
Invite Request flow
A -- > opensips (registrar) --> opensips (tcp proxy) --> B
Problem . Sometime tcp connection between TCP proxy and B breaks down , at that
time TCP proxy sends "477 Send Failed " .
A--> Opensips (registrar)--> opensips (tcp proxy) -\\-> B
A <-- Opensips (registrar) <-- (477 send Failed) Opensips (tcp proxy)
What I am trying to do is , If B is register from 2 location and registrar
server has 2 contact in the data base .When Invite come for B , then it try 1st
contact and if TCP proxy not able to send that request to B and sends back "477
send failed " to registrar .
Now My registrar server sends that 477 back to A . But I want registrar o do
failover and send the same Invite to 2nd destination rather than sending error
message Back to A .
As for my understanding it not doing failover because proxy 1st sends "100
trying " for invite then "477 send failed " .
Is there any option through which I can do this ,
Failover block in my registrar config :
failure_route[3] {
# the previous contact is not good
if (t_check_status("408|404|477|486|50[234]|603")) {
# route to the next contact
if (next_branches()) {
# prepare for lcr failover
xlog( "L_NOTICE", "[$Tf] FR: $ci Next contact $fU ->
$tU via $rd\n" );
#t_on_reply("1");
t_on_failure("3");
if (!t_relay()){
exit;
}
} else {
xlog( "L_WARN", "[$Tf] FR: $ci No more buscuits in the
biscuit tin -> 503.\n" );
#t_reply("503", "Service unavailable -- no more
gateways");
exit;
};
};
exit;
}
Please do help . I am blocked in a production environment .
Thanks & Regards

Sasmita,
can you try with this setting :
# Disable automatic 100 Trying
modparam("tm", "auto_100trying", 0)
