<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>
<br>
Regards,<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","$avp(<wbr>ringtimeout)/usr_preferences")<wbr>; <br>
if($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>
