Hi,

Just a follow-up about my issue.
As I was not able to remove the dialog as I wanted, I preferred to create a new 
small RPC command to handle it.
This new command forces a dialog (identified by call-id and tags) to be removed 
“silently” (i.e. without taking care of accounting, dialog end routes… and all 
the other stuff: I did not need to because the goal of the command is to deal 
with “ghost calls”).

It just updates state of an active dialog (in state 4) to the “deleted” state 
and updates the stats.
It only handles dialog in state 4 because I have no issues with others (dialogs 
in state 3 are regularly removed from memory after the corresponding timeout).

After executing this new command: dialog is completely killed a few minutes 
later when the timer function dlg_clean_run is executed.
(and we can see in the logs the below line:)
NOTICE: dialog [dlg_hash.c:257]: dlg_clean_run(): dialog in delete state is too 
old

Command can be executed from script using the Jsonrpc server module.
I am not sure it could interest other users (could be “dangerous” and scope is 
limited) but if you think it could then I would be happy to make a PR on git.

Cheers,

Hi Henning,

Thanks for your reply. There is no particular errors in logs at dlg_bye() time.
The dialog is not removed until the original timeout is reached (i.e. some 
hours later). Of that I can be sure because of the log below printed at that 
time:

WARNING: dialog [dlg_handlers.c:1616]: dlg_ontimeout(): timeout for dlg with 
CallID '___' and tags '___' '___'

During some attempts I managed to get a working scenario (with timeout 
triggered right after BYE request and dialog no more present in memory).
But for now to be honest I do not understand why it worked at these times and 
not most of the time…
I wonder if dlg state stored in memory and/or in DB could have an impact 
regarding this behavior (the routing script indeed uses the real-time db mode 
and the dlg_db_load features).
My first impression is that depending on how the ACK request was handled within 
the dialog, the behavior is different. But I will check it further when I find 
some time.

Thanks again!

Regards,

Hi Julien,

do you get an error from the dlg_bye() execution in the logs? Can you check if 
the dialog maybe only sitting there for some more seconds until the delete 
timer will delete it after the cmd execution?

Cheers,

Henning

I make it receive a 4xx reply (Call does not exist)

I tried the end_dlg rpc command but result is the same as the dlg_bye function 
(mistake in my original message, I said send_bye but I meant dlg_bye()): BYE 
requests are sent but dialog is still present when I execute the command 
dlg.list. It does not look to be removed from the active dialog list.

Would it be because Kamailio does not get any replies to the Bye requests?

In simple works, you want to terminate a certain call?

If so: https://kamailio.org/docs/modules/5.1.x/modules/dialog.html#idm1195

Like for example via RPC: kamctl rpc dlg.end_dlg 1686 10139

Hi,

I am wondering if there is any way to remove an entry from the active dialog 
list?
I mean, assuming that Kamailio did not get any BYE related to a call for some 
reason and that I want that call to be “killed” from dialog memory before 
reaching the lifetime timeout.

What I already tried with no success: sending a request to Kamailio catched by 
a dedicated route of the script then:

·         using the dlg_get function (with the target call as parameter) then 
send_bye function (then dropping the BYE request generated by the dialog module 
in the onsend_route with the drop function): no success. Dialog module 
correctly generates BYE requests but dialog related to the call is kept in 
memory until its lifetime timeout (and BYE requests are not dropped in the 
onsend_route either).

·         using the dlg_get function then dlg_set_timeout to set a very low 
timeout value for that particular call. No successs: Trying to update a bogus 
dlg as critical error.

Could some RPC commands or whatever help me to accomplish what I try to do?
Thanks

Julien
