Re: [Kamailio-Users] [OpenSIPS-Users] Where are going my pua_dialoginfo publishes ?

Hi all for a new debug day ;)

You're right Klaus, from my understanding :

• the expires value is taken from the dialog struct, or from

override_lifetime if it's set. ==> at this point, dialog->lifetime = 0, so if override_lifetime isn't set the expires will equal 0 too. so we need to go more deeply.

(not in call order)

• the dialog struct is given via the callback and filled by the dialog

module

• the dialog module calls get_dlg_timeout function which return the avp

lifetime or default_timeout if the avp doesn't exist

• the dialog module calls run_create_callbacks which then calls

registered callbacks like pua_dialoginfo's one

the weird thing, from dialog/dlg_handlers.c line 470 to 510, the dialog struct is built but the lifetime field is filled after the run_create_callbacks call...

I remember I have come across this before. Currently the order is:

/* first INVITE seen (dialog created, unconfirmed) */ run_create_callbacks( dlg, msg);

if ( seq_match_mode!=SEQ_MATCH_NO_ID && add_dlg_rr_param( msg, dlg->h_entry, dlg->h_id)<0 ) { LM_ERR("failed to add RR param\n"); goto error; }

if ( d_tmb.register_tmcb( msg, t, TMCB_RESPONSE_OUT|TMCB_RESPONSE_FWDED, dlg_onreply, (void*)dlg, unref_new_dialog)<0 ) { LM_ERR("failed to register TMCB\n"); goto error; }

dlg->lifetime = get_dlg_timeout(msg);

I wonder if it should be changed. Shouldn't run_create_callbacks() executed later? E.g. If there is an error creating the dialog IMO it makes no sense to call the callback at all.

Daniel, what do you think?

I wonder why the lifetime was 0 at all?

The lifetime should be the lifetime from the dialog module, and a
liftime of 0 makes also in dialog module no sense.

    Daniel was right !

    I've changed override_lifetime pua_dialoginfo's parameter and
    it's now working !

       Actually we still do not know if you use Kamailio or Opensips
    (which
       have slightly different implementations)

       The PUBLISh should be sent to: publish uri= sip:alice@domain

       If "domain" is yourself, it should be looped to the proxy via
       loopback interface (ngrep -d lo port 5060)

           Hi,
            I'm trying to use *_dialoginfo modules but I'm facing to a
           missunderstanding, or a bug.
           In fact, the presence server is working and I'm also able to
           subscribe to dialog event.
           But when pua_dialoginfo uses pua to send the Publish, I don't
           know where it going...
           I even not sure publishes are really sent.
