Re: [SR-Users] Kamailio dialog termination

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");

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.

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?

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.
