Re: [SR-Users] Dialog module isn't decreasing the profile size, and isn't entering on event routes

Hello,

should work without dlg_manage() for bye, but it depends on dialog matching mode and if did parameter is mirrored back in Route header. If you can't trust the client or are not sure about dlg matching mode, it is better to call dlg_manage() for BYE.

Cheers, Daniel

Hi Daniel, I wasn't executing the dlg_manage on BYE requests I thought that i only needed execute it on INVITES messages.

it's working now after adding:

if(is_known_dlg()) { dlg_manage(); }

Thank you for your support

Hello,

do you execute dlg_manage() for BYE requests? Or, if you rely on
the parameters to route headers, look at the BYE and see if it is
there.

Cheers,
Daniel

Hi there,

I'm using a dialog module in a small kamailio script that only
does  routing based on prefix, and relay the invite from one
ipaddr to another ip addr (diferent interfaces) using $fs variavel.

Now i was introducing the dialog module to limit the number of
concurrent calls, and i noticed that it only can increasing the
number of dialogs, and it isn't  decreasing when receives the
"BYE", I also noticed that when kamailio receives "BYE"  the
dialog event route for state "end" is not executed.

To count the number of concurrent calls I'm using the following
logic in main route:

if (is_method("INVITE")) {
                        setflag(FLT_ACC); # do accounting
                        dlg_manage();

if(get_profile_size("concurrentcalls","local","$avp(s:size)"))
                        {
                                if($avp(s:size) != $null)
                                {
                                        xlog("L_INFO", "Number of
calls for this server : $avp(s:size) - ID=$ci\n");    
                                        if($avp(s:size) >=  15000)
                                        {
                                                xlog("L_INFO",
"Concurrent_max calls exceeded $avp(s:size) for caller '$fU' -
R=$ru ID=$ci\n");

sl_send_reply("503", "Channel limit exceeded\n");
                                                exit;
                                        }

                                }
                        }
                        set_dlg_profile("concurrentcalls","local");
                }
