Yes, I saw the event routes in new version and that
seems relevant.
Yes deleting entries from hash table is definitely logical but what
about hash entries for calls which are in-call for like 4~10 hours !!
will hashtable delete those entries !
auto-expire was designed for this purpose,
but, iirc, you said you don't
want to use it, any reason?
So I was thinking that I definitely need a mechanism in my hash table
entries to refresh which enteries have corresponding active calls
(dialogs) and which entries should be deleted as no call for them is
found !
You can correlate by call-id/dialog id the hash table content and the
list of active dialogs from dialog module -- you will have to write some
code for it.
I simply can't depend on the expiry time of hased
entries - that will
render the logic useless. Think of an entry which shouldn't be in the
table , an new call for that destination comes in and Kamailio will
think that (due to useless entry in h-table) destination is in call
and lets not send him any more calls !!
This is only when BYE is missing, which with old version of dialog was
more or less the same -- dialog will look like being active until dialog
timeout is triggered (if auto-exipre and dialog timout are the same
value, then practically both modules will remove the data associated
with that call at the same time). With newest version 3.3, dialog can do
options keepalives, practically able to detect if a call is down, then
the event route is triggered and you can delete from htable as well.

Daniel

Hi,
sure, I'll give that debug messages a try tonight, Also I was
thinking of alternative approach and like you said, you are using
htable. If I've to use that htable entry manually how do I make
sure that any call data gets only deleted/erased after the call
hangsup !? i.e I don't want the htable entry to get expired and
removed automatically for a call length greater than 3 hours !!
the call ends when the BYE is coming through, so at that time you
can delete from htable -- if the BYE is missing, then the htable
auto-expire will clean it (like dialog auto-expires will do it for
dlg case).
Just as side note, in 3.3.0, dialog module exports events routes
executed when a call is started or ended, so you can do easier
operations related to this events (e.g., no matter dialog is ended
by a bye or timeout, you will get a specific event route
executed), see:

Hello,
do you get any hints about what happens if you run with
debug=3? When dialog is deleted from database, is any other
query sent to delete the dialog vars? This features was not
used by me so far, still relying on htable for my needs of
such cases.
You can send the logs here for troubleshooting.
Cheers,
Daniel

Hi Sir,
I've used the funcation as you informed. /$dlg_var(incall) =
$fU; / It do insert my desired value into the dialog_var
table but it don't gets deleted on call hangup !
I'm executing this code in my ON_REPLY route:
onreply_route[REPLY_ONE] {
xdbg("incoming reply\n");
if(is_method("BYE"))
{
unset_dlg_profile("incall","$fU");
dlg_resetflag("4");
}
....
Still I can't seem to erase the values :(
Please suggest.
Best Regards,
Sammy G.

Thanks,
The reason why I didn't scroll down to it was because it
was not listed under the functions list. Thanks for
this. I'll give it a try.
Next question is, will the values stored in this
dialog_vars be matched if I execute the function
/is_in_profile("my-profile") ?/
The problem with the alternative approach ,what I think,
could be that I'd have to make sure that the required
KVPs are stored in my hashtable for the length of the
call active.
I'd definitely not want my configurations file to behave
abnormally if the hastable entry value gets expired
meanwhile the corresponding call is still active.
Also Sir, I posted a previous email regarding the values
not getting expired from "dialog" table even after the BYE !
Thanks again,
Regards,
Sammy G.

Hello,
to store in a value in a dialog_var record, you have
to set a PV for it:
http://kamailio.org/docs/modules/stable/modules_k/dialog.html#id2555403
Alternative, you can use hashtable with a key
composed from dialog id (or callid) and some other
string to identify your value.
Cheers,
Daniel

Hello
I've two problems regarding dialog module- used for
profiling users that are in-a-call.
My topology is quiet simple.
SIP-USER-71141---->Kamailio------------->Asterisk[AGI]||
CALLEE<-----------------Kamailio<--------------------------------||
1- I wish to store my custom SIP header value in
profiles.
I'm having trouble in figuring out on how to use
Dialog_vars table in my kamailio server. I'm using
dialog module to profile SIP users that are in call
or making a call. It works well and the dialog
maintains an entry when the call is established.
Now, the difficult part is that I want my custom
header to be inserted into either dialog table or
dialog_vars table such that when I do a query
"*is_in_profile("$avp(my_value)")*" it returns me a
result.
2- Alternative to 1, I can log A,B leg separately
but it doesn't erase all data on call hangup.
Asterisk AGI changes the caller-id of SIP-USERA
such that if it was 71141 it would be something
like "007" on its way out to destination via
kamailio. Now, at this point in kamailio when the
call is answered by destination the dialog module
saves the call data with values corresponding to
"007" and not "71141".
I have to disable the "dialog", "detect_spirals" in
order to count this one call as two separate
entities BUT problem occurs when on hangup the
B-Leg gets erased from the table but the A-leg
remains in DB for as long as infinity.
Please help me in this.
Let me know if more details are required from me.
Regards,
Sammy G.
