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 Panda* *Senior Network Testing and Software Engineer* *3CLogic , ph:07827611765*
