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

<div class="moz-cite-prefix"><tt>Hi,<br>
<br>
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 :) ). <br>
<br>
What seems to be the exact problem now ?<br>
<br>

<div>But I did put the check before create_dialog("B") in the

<div> </div>
<div>if (is_method("INVITE")) {<br>
xlog("active dialog is

<div>So what is wrong in the script?</div>

I found there are many questions about "Concurrent

I appreciate your advice very much, more detailed the
