回复: 回复: 回复: Dialog Concurrency Control Issue.

jing
hi,Bogdan.
 
I just want to limit the total number of active dialog. And now I have 2 questions .
 
I changed the script like this:
 
if (is_method("INVITE")) {
                xlog("active dialog is $stat(active_dialogs)");
                xlog("dlgcount is $DLG_count");
                if ($stat(active_dialogs)>=1){
                sl_send_reply("503", "Service Unavailable");

                }
                # create dialog with timeout
                if ( !create_dialog("B") ) {
                        send_reply("500","Internal Server Error");
                        exit;
                }
                setflag(ACC_DO); # do accounting
        }
Then I started 3 dialog, they were all successful , but no 503 sent. The log showed:
active dialog is 2
dlgcount is 2
 
I used opensipsctl fifo command to show the dialog statistics, it showed
dialog:active_dialogs = 3.
1.what is wrong in my script ?
2. How to end the dialogs which have been active long time ,but have no response.
 
Or is there other way to limit the total number of active dialog?
 
I am a newbie to opensips,  would you please tell me more detailed advice?
Very thanks!
kind regards

Hi,

I see you added the missing "exit" after the sl_send_reply() and you do create the dialog for each INVITE (hopefully only for the initial ones :) ).

What seems to be the exact problem now ?

Because you need to have an "exit;" after the sl_send_reply():


                if ($stat(active_dialogs)>=1){
                sl_send_reply("503", "Service Unavailable");
               exit;
                }

Otherwise the script execution will continue.

Place a xlog message inside the IF statement, to see if you ever get there :


                if ($stat(active_dialogs)>=1){
                xlog("we have more than 1 call(s) - currently $stat(active_dialogs) \n");
                sl_send_reply("503", "Service Unavailable");
               exit;
                }

Because you need to have an "exit;" after the sl_send_reply():


                if ($stat(active_dialogs)>=1){
                sl_send_reply("503", "Service Unavailable");
               exit;
                }

Otherwise the script execution will continue.

I just want to limit the total number of active dialog. And now I have 2 questions .
 
I changed the script like this:
 
if (is_method("INVITE")) {
                xlog("active dialog is $stat(active_dialogs)");
                xlog("dlgcount is $DLG_count");
                if ($stat(active_dialogs)>=1){

                # create dialog with timeout
                if ( !create_dialog("B") ) {

                        exit;
                }
                setflag(ACC_DO); # do accounting
        }
Then I started 3 dialog, they were all successful , but no 503 sent. The log showed:
active dialog is 2
dlgcount is 2
 
I used opensipsctl fifo command to show the dialog statistics, it showed
dialog:active_dialogs = 3.
1.what is wrong in my script ?
2. How to end the dialogs which have been active long time ,but have no response.
 
Or is there other way to limit the total number of active dialog?
 
I am a newbie to opensips,  would you please tell me more detailed advice?
Very thanks!
kind regards

Hi,

I see you added the missing "exit" after the sl_send_reply() and you do create the dialog for each INVITE (hopefully only for the initial ones :) ).

What seems to be the exact problem now ?

Hello,

How many listener processes have you configured on your interface? If more than one, are you creating those 3 dialogs one at a time, or concurrently?

Hi,
OK, that's good. But not enough - as Liviu mentioned in a separate email, the test and set you do (check the number of dialogs and create a new dialog) is not an atomic operation, considering the fact that opensips is doing multi-processing. You should protect that test&set operation with a lock, to make it atomic. see:
    http://www.opensips.org/html/docs/modules/1.11.x/cfgutils.html#id294109

Because you need to have an "exit;" after the sl_send_reply():


                if ($stat(active_dialogs)>=1){
                sl_send_reply("503", "Service Unavailable");
               exit;
                }

Otherwise the script execution will continue.

hi,Bogdan.
 
I just want to limit the total number of active dialog. And now I have 2 questions .
 
I changed the script like this:
 
if (is_method("INVITE")) {
                xlog("active dialog is $stat(active_dialogs)");
                xlog("dlgcount is $DLG_count");
                if ($stat(active_dialogs)>=1){
                sl_send_reply("503", "Service Unavailable");

                }
                # create dialog with timeout
                if ( !create_dialog("B") ) {
                        send_reply("500","Internal Server Error");
                        exit;
                }
                setflag(ACC_DO); # do accounting
        }
Then I started 3 dialog, they were all successful , but no 503 sent. The log showed:
active dialog is 2
dlgcount is 2
 
I used opensipsctl fifo command to show the dialog statistics, it showed
dialog:active_dialogs = 3.
1.what is wrong in my script ?
2. How to end the dialogs which have been active long time ,but have no response.
 
Or is there other way to limit the total number of active dialog?
 
I am a newbie to opensips,  would you please tell me more detailed advice?
Very thanks!
kind regards

Hi,

I see you added the missing "exit" after the sl_send_reply() and you do create the dialog for each INVITE (hopefully only for the initial ones :) ).

What seems to be the exact problem now ?

hi,Schneur.
Thanks for your advice.
But I did put the check before  create_dialog("B")  in the original oprnsips.cfg:
 
if (is_method("INVITE")) {
                xlog("active dialog is $stat(active_dialogs)");
                if ($stat(active_dialogs)>=1){
                sl_send_reply("503", "Service Unavailable");
                exit;
                }
                # create dialog with timeout
                if ( !create_dialog("B") ) {
                        send_reply("500","Internal Server Error");
                        exit;
                }
                setflag(ACC_DO); # do accounting
        }
 

So what is wrong in the script?
And I still want to know how to judge a call is "active_dialogs"?
Thanks a lot.
 
regards,
jing

You need to do this before the create_dialog() call

Thanks for your reply.But I have another question, I used  active_dialogs  in the cfg file as this:
 
if (is_method("INVITE")) {
                if ($stat(active_dialogs)>=1){
                sl_send_reply("503", "Service Unavailable");
                }
But it seems not right.
I use sipp to test the limit ,but when the value of active_dialogs aim to the number I set ,
opensips sent 503,but  the value of active_dialogs sitll increase.
So I want to know how the value of this paramer comefrom.
Or is there something wrong in my cfg document?

Jing

Very simple, before creating a new dialog check how many open dialogs exist.

 I want to limit the total number of active dialogs ,what should I do ?

I found there are many questions about "Concurrent calls limitation " based
on per user, it's not what I need.

I appreciate your advice very much,  more detailed the better.

Thanks,
