Hi,
Thanks for picking this up.
There are no revert_uri()s in my kamailio.cfg.
Here's my test:
I send invite to "*26(a)vc2.connection-telecom.com" from my client on
172.16.230.1.
My Kamaillio config first sends the request upstream
That challenges and eventually a second authenticated invite is sent.
upstream sends back a 500
In failure_route MANAGE_FAILURE we call route block TRYASTERISK which
pushes the call to 127.0.0.1:5070
This is in the logic below.
What I find is that if the call to Asterisk also fails I come back again
into TRYASTERISK and $rd for this branch still points to the original
upstream destination (vc2.connection-telecom.com).
It seems to be harmless and another invite isn't actually sent to Asterisk.
Don't really get that so I apologise if I'm being stupid.
I've attached my kamailio.cfg and also the trace you requested.
Thanks for any pointers.
Steve

Hello,
$rd is the domain from the latest r-uri, not from original r-uri. Can you
check to be sure there is no revert_uri() used somewhere around?
If still a problem, then load debugger module, set its parameter cfgtrace
to 1 and send the log messages here to see what actions are executed, maybe
some revert the uri inside.
Cheers,
Daniel

Hi -
Can someone help me understand how pseudo-variables interact with
branches?
I've written this logic in my failure route to do a reroute of calls if
the primary destination fails:
if ( is_method("INVITE") && !t_check_status("407")
&& ($rd !=
"127.0.0.1") ) {
# Maybe should also check its not just a Busy or similar
xlog("L_NOTICE","SLD: INVITE failed $rm ($mt / $rs $rr):
$ci::$ft; try via asterisk instead\n");
append_branch("sip:$rU@127.0.0.1:5070");
send_reply("181", "Rerouting call via local
failover");
$avp(senttoast) = 1;
if (!t_relay()) {
sl_reply_error(); # or reply_error ?
}
I'm trying to check if the call was already rerouted - by looking at
$rd. But in fact I find that $rd keeps the domain from the ORIGINAL invite
even if the call that just failed was the one to 127.0.0.1:5070 .
So I'm obviously missing something about how pseudo-variables interact
with the branching etc.
Thanks,
Steve
