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.

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_dialogssitll 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 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,
