[OpenSIPS-Users] How to identify a 4xx, or 5xx, or 6xx SIP response in OpenSIPS script? Almost there...

[Rodrigo Pimenta Carvalho]

Hi.


Thank all of you!

I'm getting success to execute some actions in my OpenSIPS when it get some responses as 4xx, 5xx, 6xx.

I have read about routes and some functions to detect such responses that come from the callee peer.


In my code I have something like this:


-------------------------------------------------------------------------------------------


failure_route[missed_call] {


        if (t_check_status("4[0-9][0-9]")||t_check_status("5[0-9][0-9]")||t_check_status("6[0-9][0-9]") ) {

                if(($fU=="porteirinho") || ($fU=="porteirinho2") || ($tU=="porteirinho") || ($tU=="porteirinho2")){


                          do some actions for me...

                }
        }
}

--------------------------------------------------------------------------------------------



However, some responses seems to be generated internally in OpenSIPS. Ex: 420 (bad extension), 404 (not found), 477, etc. For these internally generated responses, I still have to find a way of detecting it. I will look for it on documentation. However, I suspect that maybe this detection has to be done in another type of route.


Should I use another type of route, shouldn't I? If yes, is there a function there that will tells me about the type of response too?


Any hint will be very helpful!



Best regards.

Hello Rodrigo,

you have to use failure route:

Hi OpenSIPS-users,


In the OpenSIPS script I can identify SIP requests, like is_method("INVITE") or is_method("BYE").


How to identify SIP responses, based on its codes that can be 4xx, or 5xx, or 6xx?

For example, how to identify that occurred a SIP response with code 483?


I just need to know that a SIP INVITE didn't succeeded.


What could be a elegant way to detect that a SIP INVITE was not answered?



Best regards.
