Unconditional Call Forward help...

I need CFU on our systems, however - it seems to work but if
the forwarded
call isn't picked up within a time limit the system just
drops the call.

My script is something like this;

(...)
loadmodule "tm.so"
modparam ("tm", "fr_timer", 30)
modparam ("tm", "fr_inv_timer", 10)

route{
	xlog("L_INFO", "Route - $fu $rm $ru");
	t_on_failure("1");

      (... Some tweaking ...)

      t_relay();
}

failure_route[1] {
      if (!t_was_cancelled()) {
      	xlog("L_INFO","Failure_route[1] -
redirect to callcentre");
            seturi("sip:callcentrelocalhost");
            append_branch();
            t_relay();
      };
      return;
}

So what happens is this;
I call a number... After 10 seconds the call
"fails" and failure_route is
invoked, whereupon the call is "redirected" to the
new uri. It rings for 10
seconds and then the the call is just terminated... (no call
to
failure_route)...

The log looks like this;
15:30:00 Route sip:useralocalhost INVITE
sip:userblocalhost
15:30:10 Failure_route[1] - redirect to callcentre
15:30:20 Route sip:useralocalhost ACK sip:userblocalhost

Any ideas? Typically I would like for the 2dn call to ring
indefinitely...

Hi Geir,

You will  need to play with the fr_inv_timer after the call
is forwarded.
You can achieve this by using avps:

Ack. I don't like AVPS 
Further, as you all may have realized, I was
trying to do call forward on busy and not CFU  ...

As you see I'm not using fr_inv_timer_avp but I would think
doing something
like

modparam("tm", "fr_inv_timer_avp",
"$avp(i:99)")

And then in the failure route before t_relay()
	$avp(i:99) = 120;

And it did 

My next question of course becomes, what happens when this
timesout?! As I
said initially I only get one call to failure_route, so
apparently when
failure_route fails it just dies?

Geir

geir,

if you have not set a new t_on_failure in your failure
route, then the
failure will be passed on to the caller.
