Ravi, 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.

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.

As you have a serial forking scenario, you do a new t_relay() at each step.

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.
