[Kamailio-Users] "408 - Request timeout" instead of "503" problem.

Hello List. I have the next situation. I'm trying to build a "LCR" but using the information from a Radius Server, so 'im using the avp_radius module to obtain the "next_gw" data from my DB. So far so good, I have been able to retry a failed call with the next gateway in the list. In my tests I'm using a list of 3 gateways and I'm seeing the next behavior : I have all the gateways off-line, so the call is redirected to the first, second and and finally to the third gateway, when there is no moer gateways to try I have this statement in my config file : if( there is gateways to try on the list... ) { route(1); } else { sl_send_reply("503", "No more DB routes"); exit; } I send the "503 - No more DB routes" but the Kamailio also send a "408 Request Timeout". What could this be happening? I even tried with just one gateway on the list, with the same results. I was expecting just the "503" message, and not the "408". Hope that someone could help me. I'm attaching my kamailio-snnipet.cfg file and a full debug with the behavior. Thanks! Ricardo Martinez
