Hello,

I have come across this behavior in Kamailio 3.1.5 version.

The proxy is behind a Firewall and uses the advertised IP to communicate to sipclients.

I have used the “dlg_match_mode”, as the record_route_preset() does not include the DID during call initiation.

modparam("dialog", "dlg_match_mode", 2)

I’m also using pua_dialoginfo to notify users about the “Event:dialog”. I have used the attached patch to make pua_dialog info aware of the dialog

I see that the dialog is being created, and the pua_dialoginfo publishes with state “trying” and “confirmed”.

When the call is cancelled/408 request is generated, the pua_dialoginfo generates the xml with state=terminated.

But when the call is answered, the dialog module updates the dialog to state=4, according to the documentation mentioned below state=4 --> Terminated.

in which documentation says state=4 is terminated? The one for the new dialog design? If yes, that is not yet implemented. In current dialog module, the state=4 is CONFIRMED.

I checked the logs and the bye is processed by the dialog module, but there is no callback to pua_dialoginfo executed. You mention above about a patch to pua_dialogninfo, but it is not attached, only test.zip which has the debug logs. Can you send the patch or be sure it does not break registering the callbacks for pua_dialoginfo?

Cheers,
Daniel

I’m not aware of the event types that fires the state to termination (I have not found the documentation about events in the dialog module).

When a BYE is received to the same call, the BYE is processed and the dialog is cleared from the memory. But the pua_dialoginfo never gets the callback for the termination and the xml is never updated.

I have attached a log for a call, please find the attached document.

I have come across a documentation about dialog module:
