okay, some tests later :-)

dlg_manage() creates a new dialog, so no access to the variables of the "real" dialog

another idea: setting $du to the server itself, then the BYE request should be processed by normal routes again. Problem is, that the did= route param is not available, so dialog can not be identified. Why not use callid, ftag, ttag? see below

dlg_get() works, but regarding SIP spirals unknown behaviour. That seems to be an generic problem, because when spirals are being used and detect_spirals is 0, a single dialog can not be identified with callid, ftag and totag only.

May that's the reason for [[ http://kamailio.org/docs/modules/stable/modules_k/dialog.html#id2966526|dlg_end_dlg]] to use h_entry and h_id for dialog identification instead of callid, ftag and ttag.

So if dialog is not loaded automatically in event-route, it would be necessary to access the mi params and to have a function do get a dialog based on h_entry and h_id.

I think that loading dialog in event-route automatically is a straightforward solution, because that is done with "normal" requests (received via socket), too.
This should be possible, if h_id and h_entry is available, which is the case for dlg_end_dlg...
