Hi, Khalil!

To be honest, I think this event was initially made to be used with the MI dlg_end_dlg command, which only terminates a dialog. However, you could run 'opensipsctl fifo dlg_list' and match the hash_id and hash_entry against the returned values, and then identify the callid.

If you would also like to receive the callid in the event, please open a feature request[1].

Hi everyone,

I am trying to understand dialog module eventing system.

I have added this route :


event_route[E_DLG_STATE_CHANGED] {

fetch_event_params("$avp(a);$avp(b);$avp(c);$avp(d);$avp(e);$avp(f)");

    cache_raw_query("redis:0", "PUBLISH serv1 fetch_event_params=$avp(a),$avp(b),$avp(c),$avp(d),$avp(e),$avp(f)", "$avp(res)");

}


so for each event I can watch an entry

1505503997.413642 [0 127.0.0.1:39734 <http://127.0.0.1:39734>] "PUBLISH" "serv1" "fetch_event_params=3917,339471624,1,3,<null>,<null>" 1505503997.524535 [0 127.0.0.1:39762 <http://127.0.0.1:39762>] "PUBLISH" "serv1" "fetch_event_params=3917,339471624,3,4,<null>,<null>" 1505504018.809746 [0 127.0.0.1:39840 <http://127.0.0.1:39840>] "PUBLISH" "serv1" "fetch_event_params=3917,339471624,4,5,<null>,<null>"


I understand that

a = hash_id of dialog
b= hash_entry of dialog
c = old_state
d = new_state
e & f = do not exist and here just to prove that they do not exist.

but I don't understand how to use the information of a & b to track dialogs ? if there a function that when fed those parameters gives us callid for example ?

Thanks in advance.
