My dispatcher configuration is:

# ----- dispatcher params -----
modparam("dispatcher", "table_name", "dispatcher")
modparam("dispatcher", "force_dst", 2)
modparam("dispatcher", "flags", 3)
modparam("dispatcher", "db_url", DBURL)
modparam("dispatcher", "dst_avp", "$avp(s:dst)")
modparam("dispatcher", "cnt_avp", "$avp(s:dsp_uri_count)")
modparam("dispatcher", "grp_avp", "$avp(s:dsp_uri_grp)")
modparam("dispatcher", "ds_ping_method", "OPTIONS")
modparam("dispatcher", "ds_ping_from", "sip:sipcheck@10.0.20.102:5062")
modparam("dispatcher", "ds_ping_interval", 10)
modparam("dispatcher", "ds_probing_threshhold", 3)
modparam("dispatcher", "ds_probing_mode", 2)


>Do you do something like "ds_mark_dst()" in your failure route?

Yes, I'm using ds_mark_dst inside of failure route, but the "REGISTER" is not entering in failure route in any case, because when "REGISTER" gets the function ds_select_dst, this function returns false and my kamailio sends a statless reply to phone and drops the message.

I did a test that was comment "ds_mark_dst("ip");" in failure route and even with this I still having the same issue.


route[HANDLE_REGISTER]
{
....
   t_set_fr(0,2000);
   t_on_failure("PRXFAILURE");

   if(!ds_select_dst("9", "4"))
   {
       xlog("L_ERR", "Failed to select proxy - R=$ru ID=$ci\n");
       sl_send_reply("503", "No proxy available, try again later");
       exit;
   }

   ...

   route(RELAY);

}


failure_route[PRXFAILURE] {
   if(is_method("REGISTER") && (t_check_status("500") || t_branch_timeout() || !t_branch_replied()))
   {
       $var(cache_user) = $tU + "@" + $td;
       $sht(prxcache=>$var(cache_user))=$null;
       ds_mark_dst("ip");
       if(ds_next_dst())
       { 
         #again set local timeout for reply
         t_set_fr(0,2000);
         t_on_failure("PRXFAILURE");
         xlog("L_INFO", "PRX FAILURE -REGISTER New dest $du ID=$ci\n");
         $sht(tmpcache=>$var(cache_user))=$du;
         route(RELAY);
         exit;
        }
        else
        {
          #last available node failed to reply, no other destinations available
          send_reply("404", "No destination");
          exit;


         }

    }
}

Hi,

quick questions:
- Do you have the Dispatcher Activity detection turned on?
- Do you do something like "ds_mark_dst()" in your failure route?
- Can you send me your config, so i can verify a few things?

Thanks,
Carsten
