LCR prefix based - sr-users

10 Mar 2016

Hi to all, 

i want to use prefix based LCR routing, but for some reason, something is not working as
expected. 

Can anyone help me? 

This is the LCR configuration:

#LCR MODULE
loadmodule "lcr.so"

modparam("lcr", "db_url",
"mysql://kamailioro:kamailioro@localhost/kamailio")
modparam("lcr", "lcr_gw_table","lcr_gw")
modparam("lcr", "id_column", "id")
modparam("lcr", "gw_name_column", "gw_name")
modparam("lcr", "ip_addr_column", "ip_addr")
modparam("lcr", "hostname_column", "hostname")
modparam("lcr", "port_column", "port")
modparam("lcr", "params_column", "params")
modparam("lcr", "uri_scheme_column", "uri_scheme")
modparam("lcr", "transport_column", "transport")
modparam("lcr", "strip_column", "strip")
modparam("lcr", "tag_column", "tag")
modparam("lcr", "flags_column", "flags")
modparam("lcr", "defunct_column", "defunct")
modparam("lcr", "lcr_rule_table", "lcr_rule")
modparam("lcr", "prefix_column", "prefix")
modparam("lcr", "from_uri_column", "from_uri")
modparam("lcr", "request_uri_column", "request_uri")
modparam("lcr", "stopper_column", "stopper")
modparam("lcr", "enabled_column", "enabled")
modparam("lcr", "lcr_rule_target_table", "lcr_rule_target")
modparam("lcr", "rule_id_column", "id")
modparam("lcr", "gw_id_column", "gw_id")
modparam("lcr", "priority_column", "priority")
modparam("lcr","weight_column", "weight")

modparam("lcr", "gw_uri_avp", "$avp(i:709)")
modparam("lcr", "ruri_user_avp", "$avp(i:500)")

modparam("lcr", "tag_avp", "$avp(lcr_tag)")
modparam("lcr", "flags_avp", "$avp(i:712)")
modparam("lcr", "lcr_id_avp", "$avp(s:lcr_id_avp)")
modparam("lcr", "defunct_gw_avp", "$avp(s:defunct_gw_avp)")

route[LCR] {
if (status=="200")
{
  xlog("LCR: Inside the LCR route\n");
}

if(method=="INVITE")
{
  xlog("We got an invite");
  if(!load_gws(1, $rU, $var(caller_uri))) {
    xlog("Couldn't load gateways");
    sl_send_reply("500", "Server Internal Error - Cannot load
gateways");
    exit;
  } else {
        xlog("GW Selected '$avp(i:709)'\n");
        xlog("Domain of destination: $dd\n");
        xlog("To URI: $tu\n");
  }

  if(!next_gw()) {
    xlog("Couldn't proceed to next gateway");
    sl_send_reply("503", "Service not available, no gateways found");
    exit;
  } else {
        xlog("Calling the first matched gateway\n");
        xlog("ruri_user_avp: '$avp(i:500)'\n");
        xlog("To URI after next_gw: $tu\n");
        xlog("Request URI: $rU\n");

  }
}
}

AND this is the error which i have got:

17(7483) ERROR: <script>: We got an invite17(7483) ERROR: <script>: GW
