[OpenSIPS-Users] How to set default_timeout for dialogs, without resetting OpenSIPS ? (continuing...)

[Rodrigo Pimenta Carvalho]

Hi Bogdan.


I have just finished studying about some parts of OpenSIPS documentation, mainly about the modules.


I saw that it is possible to take control of call duration using Call Control,which is too complex to my simple needings as my projetct doesn't need a charging system, or using DLG_timeout as you well pointed.


So, in my OpenSIPS script I should do something like this:


        # account only INVITEs
        if (is_method("INVITE")) {

                # create dialog with timeout
                if ( !create_dialog("B") ) {
                        send_reply("500","Internal Server Error");
                        exit;
                }

                $DLG_timeout = <some variable with amount of seconds>;

        }


However the final user is the one who must define how long a call can exist. Such configuration will be done via a proprietary GUI in my project, any time.

So, I was looking for a way to set  'some variable with amount of seconds' and pass it to OpenSIPS, before starting calls. That is, how can OpenSIPS read a external variable or how to write DLG_timout via MI ? I didn't find a solution.


Then, my development team has decided to put a new field (X-Timeout) in the SIP INVITE header, configuring it with the desired amount of seconds.

So, in the OpenSIPS script we could read the value from X-Timeout and set it to the DLG_timeout.


What do you think about this approach? Is it simple to read a header field from SIP INVITE, isn't it? I will take a look in the documentation.


Any hint or suggestion will be  very helpful!!


Thanks a lot!

Hi Rodrigo,

The timeout for a call can be set (in a per-call manner) when the call starts (during re-INVITE) or during any sequential requests (ACK, re-INVITE), etc. See DLG_timeout variable:
    http://www.opensips.org/html/docs/modules/1.11.x/dialog.html#timeout-pvar-id

If you want to tear down the call, use the dlg_end_dlg MI command :
    http://www.opensips.org/html/docs/modules/1.11.x/dialog.html#id296795

Dear OpenSIPS-Users,


A kind of management application in my project must provide an way of a  system manager sets the default_timeout for dialogs in our already running OpenSIPS. How to do it?


I was looking for an way of sending a command to OpenSIPS 2.2 to configure it to tear down (hang up) every call after a determined timeout. So I have just read about MI, dialog exported MI functions and dialog exported pseud-variables. What I want is to configure the default_timeout without having to reset the OpenSIPS.


However, I didn't find a way of doing that. I was thing about to use mi_fifo and a exported command, but no way.


Is there a way of controlling the default_timeout for dialogs, while OpenSIPS is running?


If not, I was thinking about changing the value of timeout column in the table dialog, for each dialog. But, it sounds a bit complicated.


Any idea?


Any hint will be very helpful!


Best regards.
