<tt>Hello Ravi,<br>
<br>
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) ?<br>
<br>
Best regards,<br>

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

<div bgcolor="#FFFFFF"> <tt>Hi
Ravi,<br>
<br>
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.<br>

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

Thanks,<br>
