Actually I already implemented that timeout, I haven’t asked about that,
because I didn’t have any problems with that one.
I am being asked for that “if a 180 comes within 0.8 seconds, cancel the
call and send a 480 to the origination.
The cancel I got it working thanks to your help. Sending back a 480 to the
origination is what’s proving more difficult, I just can’t figure that one
out.

Wouldn’t it make more sense to just have an aggressive
timeout for the
“keeping it there” aspect?
That is, if, upon receipt of a non-100 1xx message, a final dispositive
reply does not follow within X seconds, route-advance to the next provider?
This can be accomplished with the t_set_fr/t_reset_fr() technique
previously discussed.
It sounds like you might be making this unnecessarily complicated. :-)
Don’t worry about how quickly they send you the progress/alerting messages;
instead, worry about how slowly they send you anything else afterward.
The only wrinkle I can see that in that is the caller experience...

Some providers have other providers which many times just answer the call
and try to keep it there. It’s a known strategy some scammers use. Getting
a 180/3 in say; 500ms (to a real-life hard line, is probably one such call.

What is the point of refusing a call that answer
with a 100/183 "too
quickly" ? ... I don't get the point on that.

Hello Alex,
Again thanks.
I'm using that calculation to, when receiving a 180/3, if it comes in too
quickly (i.e. 100ms) i cancel that call, and send a 480 the the A leg.
I haven't found way of doing this, is this possible at all? I trired
setting a very low t_set_fr(10,10) (0 means set the default), but that's
not working...
Is there a way of doing this?
Thanks!

David Villasmil

Thanks Alex,
Exactly what I was thinking. Just wondering whether there was a better
way.
Again THANKS!

Hi,
You can store the timestamp of the last message of interest in a
transaction-persistent variable - that is, an AVP or XAVP - using $TV():
https://www.kamailio.org/wiki/cookbooks/5.4.x/pseudovariables#tv_name
Then, you can do some arithmetic like this to turn the difference
between two timestamps into milliseconds. This is stolen straight from CSRP
so adapt to your needs. :-)
# Log request processing time.
$var(cur_time) = $TV(Sn);
$var(proc_diff) = (
(((
$(var(cur_time){s.select,0,.}{s.int}) -
$(avp(proc_start){s.select,0,.}{s.int})
) * 1000000)
+
(
$(var(cur_time){s.select,1,.}{s.int}) -
$(avp(proc_start){s.select,1,.}{s.int})
) / 1000) mod 1000
);

Hello all,
Is it possible to know the elapsed time since the previously received
message?
On outgoing calls, I.e: when i get a 180, how long did the 100 arrived?
Or the INVITE...
Thanks
David
