[OpenSIPS-Users] trying to understand the E_DLG_STATE_CHANGED

Using E_DLG_STATE_CHANGED to keep a count of active dialogs seems reasonable.  If you want the callerID, you would use the “hash_id of dialog” and the “b= hash_entry of dialog” to look up the dialog in the table and get more info like the callerid.  You use the dlg_list command to look up data in the table. I don’t know if you could do this in the openSIPS config file alone, you likely have to have a script that is called to query the table, parse the data you want, ….

Looks like the key is of the form:

<hash_id>:< hash_entry> like “1527:459551172” below

Example of details from dlg_list:

rmundkowsky: ~$ /export/Apps/opensips/sbin/opensipsctl fifo dlg_list
database engine 'MYSQL' loaded
Control engine 'FIFO' loaded
entering fifo_cmd dlg_list
dialog::  hash=1527:459551172 dialog_id=6558874612164

Hi Răzvan,

Thanks for your answer.

I ended up using onreply_route and checking if ($rs == "200") to increment connect_calls and then event_route[E_ACC_CDR]  to decrement connected_calls.

multiple local tests are giving expected behavior, will need to test on production to confirm though.

Thanks a lot for your help.

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

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.
