Arun:

I would try something like the following:

if (!load_gws()) { sl_send_reply("500", "Server Internal Error - Cannot load gateways"); break; } else { xlog("L_INFO", "\n[SER]: - [$Tf] Method: <$rm> R-uri: <$ru> From: <$fu> To <$tu> : Successfully Loaded Gateway List\n"); };

......

if (!next_gw()) { t_reply("503", "Service not available - No more gateways"); break; } else { t_on_failure("2"); <--- This will be where you load the next gateway t_relay(); break; };

failure_route[2] {

if (!next_gw()) { xlog("L_CRIT","No more gateways for <$tu>\n"); t_reply("503", "Service not available - No more gateways"); break; } else { t_on_failure("2"); t_relay(); break; } }
