Hello again,
Related question: how to log destination ip/port of dispatcher set from
failure_route?
$si:$sp works as expected in onreply_route block:
onreply_route[MANAGE_REPLY] {
xlog("L_NOTICE", "$rr ($rs) [$cs] ($ci) $si:$sp - $ua\n");
if ( t_check_status("(503)|(408)|(480)") ) {
xlog("L_WARN", "Server will be blacklisted: $si:$sp ($rs)\n");
}
}
I tried to use this example
http://www.kamailio.org/wiki/cookbooks/5.2.x/pseudovariables#t_req_pv, but
get <null>:
failure_route[MANAGE_FAILURE] {
if ( !t_check_status("(503)|(408)|(480)") ) {
exit;
}
xlog("L_WARN", "Server will be blacklisted: $T_rpl($si):$T_rpl($sp)\n");
ds_mark_dst("IP"); # Set current server to probbing state
$si:$sp without T_rpl returns address and port of client.
