Hi, Ravi!<br>
<br>
What do you mean "main route"? - the main route should be called
only once, when the INVITE comes from 1111. Are you looping the
message back to you?<br>
<br>
PS: your message was detected to be too large - when you receive
back errors related to this, please revise them and then send the
message in a reasonable format.<br>
<br>
Best regards,<br>

<div>Dear Bogdan,<br>
<br>
Apologize for the late reply.<br>
<br>
I was checking my logic and your suggestions in lab.<br>
<br>
Finally what my observation is,<br>
1)<br>
I set an avp variable in main route. say for example:
$avp(test)=0<br>
<br>
that I found it in failure_route and I am incrementing it by
1 and call forwarded to OpenSIPS again.<br>
Now in main route I am not able to get that variable, but
yes when call went again to failure_route on failure case ,
I got its value 1 and able to increment it by 1.<br>
<br>
<br>
2)<br>
Second thing I found is:<br>
<br>
Say for example my call scenarios is: <br>
1111 --> 2222 --Forward on No Answer--> 3333
--Foraward on No Answer--> 4444<br>
<br>
-----------------------<br>
<br>
1111 -> 2222 : 2222 did not answer.<br>
in Failure_route, I set append_hf("test: 1\r\n"); and call
forwarded to OpenSIPS again with $rU=3333.<br>
<br>
2222 -> 3333 :<br>
In Main Route I am able to get its value.<br>
***** Now I use remove_hf("test"); before forwarding call to
3333.<br>
3333 did not pick up the call.<br>
call lands on failure_route.<br>
in Failure_route, I set append_hf("test: 2\r\n"); and call
forwarded to OpenSIPS again with $rU=4444.<br>
<br>
3333 -> 4444 :<br>
In Main Route when I fetch $hdr(test), I got the value 1
instead of 2. When I check its SIP trace, I found two
headers with name "test" with values 1 and 2.<br>
<br>
------------------<br>
<br>
So, remove_hf at ***** removes it from the OutBound SIP
packet, but it is not removed at failure_route.<br>
<br>
<br>
I hope I explained well(It is a bit complex).<br>
<br>
Let me know if you need anything else to debug it.<br>

<br>
I have to admit I did not understand your whole
scenario, but you can read SIP headers in failure route,
for sure. I think you are more fighting how the changes
are done per-branch in OpenSIPS - whatever you change in
request route (as changes) will be inherited by all
branches/forks of that transaction. What you change in
failure route will propagate only for that new branch.<br>
<br>
IF you want to count the number of serial forking
attempts, better use an $avp(_name_) variable - you can
init it to 0 in request route and increment it each time
you do a new t_relay().<br>
<br>

<div>Dear Bogdan and Ben,<br>
Thanks for your replies.<br>
<br>
</div>
Previously, I set t_on_failure() when
forwarded call came back to
OpenSIPS(not in failure_route) , Now
after your suggestion I set <b>t_on_failure()</b>
before <b>t_relay()</b> in <b>failure_route</b>.
<br>
<br>
</div>
That Indeed solved the issue of
forwarding and timeout, but faced
another issue after this change.<br>
<br>
</div>
Here is the brief of issue: <br>
<br>
</div>
in failure_route, I fetched some <b>headers</b>
from <b>SIP Message,</b> that checks the
number of forwarding and if not exceeded max
count, it proceed to forward the
call(t_relay()).<br>
</div>
Now in this logic I added <b>t_on_failure()</b>
before <b>t_relay()</b> , now here I am not
able to get the headers from SIP Message in
failure_route where I am checking the max
forwarding count.<br>
<br>
</div>
Is there any way to get the headers in
failure_route after using t_on_failure in
failure_route ??<br>
<br>
</div>
Hope I explained well.<br>
<div><br>
</div>
<div>Let me know If you need anything else from my
side.<br>

<p class="MsoNormal">Are you sure you are
arming the failure route after each step
using t_on_failure? It sounds like you
are only doing this on the call to 2222,
which allows you to failover to 3333.
But when you send to 3333 you have to
arm the failure route again.</p>
