Re: [Serusers] Please help with LCR - sr-users

Arun:

 This depends a little on your configuration. Generally speaking the 
!load_gws and !next_gw would be in route block 0. You will most likely 
want to do any per-call checks or rewrites before determining which 
gateway should receive the call. The failure_route can be inserted after 
your route blocks.

     I would try something like the following:

            if (!load_gws()) {
               sl_send_reply("500", "Server Internal Error - Cannot load

            };

            ......

            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();

           failure_route[2] {

            if (!next_gw()) {
               xlog("L_CRIT","No more gateways for <$tu>\n");
