Hello,

I've set the default_timeout to 3600 seconds, which is 1 hour.
In the database the dialog record shows:
StartTime            Timeout
1366886241         1366929441
The difference is 12 hours. Shouldn't the timeout be StartTime + 
default_timeout?

Also the matching mode is set to 1, which is DID_FALLBACK.
DID_FALLBACK: the match is first tried based on DID and if not present, it will 
fall back to SIP matching. I'm assuming SIP matching is done based on CallID 
and Tags?

Why does the dialog module still reserve a 'port' even if the profile_size is 
0, but the dialog:active_dialogs is 1?

Below a sample of my configuration script which handles the call limit.

       dlg_manage();
       record_route();
       $var(SIZE) = 0;

       sql_query("vf", "exec dbo.SelectCurrentTimeFrame '00$rU'", "ra");
       $avp(s:limit) = $dbr(ra=>[0,7]);
       xlog("L_INFO", "Maximum simultaneous calls is configured at 
$avp(s:limit) ....");
       sql_result_free("ra");

       get_profile_size("limitedCallsProfile", "$rU", "$var(SIZE)");

       xlog("L_INFO", "There are currently $var(SIZE) calls for $rU, excluding 
the current call");
       if($var(SIZE) >= $avp(s:limit)) {
              xlog("L_INFO", "Simultaneous calls limit of $avp(s:limit) reached 
for $rU: $var(SIZE)\n");
              sl_send_reply("603", "Simultaneous calls limit reached");
              exit;
       }

       set_dlg_profile("limitedCallsProfile ", "$rU");

Thanks,

Grant

Hi,

did you wait the default 12 hours (default_timeout) for the dialog to be 
released? If after that time, the dialog is still there, it is probably because 
of a bug.

You should also take into account the matching mode currently configured: 
http://www.kamailio.org/docs/modules/3.3.x/modules_k/dialog.html#idp129680. The 
default behavior is to add a dialog-id cookie in the route header but if your 
user agent fails to add the parameter when it sends the subsequent requests, 
the dialog will not be properly tracked and you could end with a bunch of 
active "unfinished" dialogs in memory.

Regards,

Hello,

Another dialog got stuck in kamailio, so I checked a few kamctl commands. This 
is what I found.

When viewing the profile size the count is 0 (using kamctl fifo 
profile_get_size [NAME])
When using the kamctl fifo get_statistics all command, the 
dialog:active_dialogs shows 1. There are no other calls active at this point, 
so this must be the one that got stuck.

The call is still in state 4. I don't know what this means, but I'm guessing 
active.

Why did the dialog module fail to release this dialog? The profile was 
configured to allow 2 concurrent calls. We called the number using two phones 
and only one made it through.

Is this a bug?

Regards,

Grant

Subject: [SR-Users] Kamailio dialog termination

Hello,

Using the dialog module. According to the documentation a dialog is 
automatically destroyed when a BYE is received. In case of no BYE, the dialog 
lifetime is controlled via the default timeout.

I'm assuming the dialog module only creates a dialog when a 200 OK is received 
on the INVITE. So if a CANCEL request is sent for this INVITE or the server 
answers with anything but a 200 OK, no dialog is created and maintained by the 
dialog module?

Also, when the dialog is terminated, is it guaranteed the dialog entry is 
removed from memory at all times, but there might be a chance the dialog 
remains stored in the database table because of some error? I'm using the 
dialog module to control the number of calls allowed to a certain destination, 
but it sometimes does occur that an entry in the database is not removed, but 
I'm not sure if the dialog is also removed from memory when this happens.

I hope someone could clear this out for me.

Thanks,

Grant
