Yes, that's exactly what I'm looking for. But there are some problems I'm
facing, which most probably is due to my own lack of understanding about
the available knobs:
1- When t-relay() return, the proxy already send the failure notice to
the client. This is not what I want, the "corrective action" must be
transparant
to the user.
2- I have two SRV's with the same weight, I do not see any kind of round-robin.
The request goes to only one of them.
Here is the (probably faulty) config:
route {
...
rewriteport ("");
#t_on_failure("1");
xlog("L_INFO", "Got the call\n");
if (! t_relay()) {
if (t_check_status("(403|487)|(408|477)")) {
xlog("L_ERR", "initial call failed\n");
if (t_newtran()) {
xlog("L_ERR", "Let's try again\n");
t_relay();
}
}
}
...
}
Can you help?
