Reply to my own message!
I've been working on this all weekend.
Had an issue with a firewall which was blocking redirect
packets, that cleared up a bunch.
Now, I have the get_redirects("*") working, serialize_branches(0) is
working (kinda, it says it has
nothing to do because all data has the same
q value), and I see a debug message when I call next_branches() which says
DEBUG:next_branches: no AVPs -- we are done!
My ser.cfg file is below. How do I get rid of 'no AVPs' error? I thought the
domain modparam would activate them?

I built a redirect server:
It basically does:
rewritehost("ab5350.node-1.com");
sl_send_reply("302", "Redirect");
I forward to the redirect server setting up a failure block:
if(is_method("INVITE"))
{
_QLOG(L_INFO, OUTBOUNDCALL, OUT);
t_on_failure("3");
record_route();
setflag(1);
setflag(2);
rewritehostport(_QSTR
(REDIRECTOBGATEWAYIP:REDIRECTOBGATEWAYPORT));
if(!t_relay())
{
sl_reply_error();
}
}
The response below comes back from my redirect server:

My failure_route block picks up the routing:
failure_route[3]
{
_QLOG(L_WARN, FAILUREROUTE, here we are);
if(status =~ "3[0-9][0-9]")
{
_QLOG(L_WARN, FAILUREROUTE, status is 3xx);
get_redirects("*");
serialize_branches(0);
}
if(next_branches())
{
_QLOG(L_WARN, FAILUREROUTE, next branch);
t_on_failure("3");
t_relay();
}
_QLOG(L_WARN, FAILUREROUTE, no branches left);
if(!t_reply("404", "Not Found"))
{
_QLOG(L_WARN, FAILUREROUTE, Error);
}
}
My syslog shows QLOG messages.
I see the 'status is 3xx' message, which shows the
next command to be get_redirects("*");
The next output I see in my syslog is 'no branches left', which
indicates that the
serialize_branches(0) and next_branches() aren't working as I expected.
I've also tried getting rid of the serialize_branches and next_branches and just
doing a t_relay() after the get_redirects(), that doesn't work either.
Since I'm trying to simulate the redirect server, and the redirect
client, I'm sure I
got one of them wrong. Can somebody give me a hint?
Thanks!
