Hello Ravi,
It looks like the failed call to 3333 has no failure route set (this is
why you directly get the 408 default timeout, as there is no failure
route to handle the timeout event). Are you sure you t_on_failure() for
each call attempt (especially when handling the call failure to 2222) ?

Dear Bogdan,
I am Grateful for your reply.
I applied *$T_fr_inv_timeout* before doing each *t_relay().* by
applying it , I am able to achieve it at 1st forwarding but
unfortunately not working for 2nd forwarding.
The scenario is:
1111
2222 (fr_inv_timeout 10 sec)
3333 (fr_inv_timeout 5 sec)
4444 (fr_inv_timeout 20 sec)
when 1111 calls 2222 : OpenSIPS generates CANCEL at 10 secs and
forwards call to 3333.
now --> 3333 : OpenSIPS generates CANCEL at 5 secs**but does not
forward call to 4444 instead it sends *408 to Caller(1111)* and drops
call.
I am attaching packets where sip.client.com <http://sip.client.com>
refers to the SIP clients and sip.server.com <http://sip.server.com>
refers to the OpenSIPS Server.
Also find the attached snapshots of the call flow.
Please guide what can be done or where I am doing wrong ?
Let me know if you need any other information.
Best Regards,
Ravi Patel

Hi Ravi,
Before each t_rely() you have to set the your custom
$T_fr_inv_timeout and $T_fr_timeout, otherwise the default values
will be used. As you have a serial forking scenario, you do a new
t_relay() at each step.

Hi Team,
What is the right way to reset timers *$T_fr_inv_timeout* and
*$T_fr_timeout* ??
I am using OpenSIPS-2.2 version
The below scenario will help to understand issue,
There are 4 SIP users,
1111,2222,3333,4444
What I want to achieve is:
1111 ---> 2222 (FORWARD ON NOANSWER) ---> 3333 (FORWARD ON
NOANSWER) ---> 4444
*1st Test Case Scenario:*
1111
2222 (fr_inv_timeout 20 sec)
3333 (fr_inv_timeout 25 sec)
4444 (fr_inv_timeout 30 sec)
when 1111 calls 2222 : OpenSIPS generates CANCEL at 20 secs
(thats working proper as expexted) and forwards call to 3333 as
per my configuration.
so in --> 3333 : OpenSIPS generates CANCEL at *20 secs instead of
25 secs* and send 408 to 1111. and not processing the 2nd forwarding.
*2nd Test Case Scenario:*
1111
2222 (fr_inv_timeout 20 sec)
3333 (fr_inv_timeout 15 sec)
4444 (fr_inv_timeout 30 sec)
when 1111 calls 2222 : OpenSIPS generates CANCEL at 20 secs (that
is working proper as expexted) and forwards call to 3333 as per
my configuration.
now --> 3333 : OpenSIPS generates CANCEL at 15 secs and forwards
the call to 4444, Here OpenSIPS generates CANCEL *after 5 secs
instead of 30 secs.*
We set timeout by using $T_fr_inv_timeout.
------------
route[ring_timeout]{
xlog("L_INFO","------------------- RING_TIMEOUT ---------------\n");
if (!is_method("INVITE"))
return;
avp_db_load("$rU","$avp(ringtimeout)/usr_preferences");
if($avp(ringtimeout)!=null)
{
$T_fr_inv_timeout = NULL;
xlog("L_INFO","$rU: Ring timeout :
$avp(ringtimeout)");
$T_fr_inv_timeout
=$(avp(ringtimeout){s.int <http://s.int>}) ;
xlog("L_INFO","$rU: Ring timeout is
setted: [$T_fr_inv_timeout]");
}
else
{
xlog("L_INFO","$rU: Ring timeout is NOT
setted");
}
}
------------------
From both the scenarios what we found, it sticks to the first
timeout of 2222,that is 20secs in our case.
In first scenario it generates CANCEL on 3333 at 20 secs instead
of 25 that is 2222's Timeout.
In second scenario it generates CANCEL on 3333 at 15sec and on
4444 at 5 sec (15 + 5 = 20 sec) that is also 2222's timeout.
Can I know the right method to set $T_fr_inv_timeout ?
Let me know if any other information is needed.
Thanks,
Ravi
