Thanks Jason. Finally got back to testing this and your insight has solved that issue thanks. I now create a new transaction if check transaction fails (which
it will of course on the initial INVITE). Now the Ro_CCR () in the ims_charging module doesn’t complain about “dialog not found”
I assume then that dialog_ng works differently than dialog module in that it creates an initial dialog on receipt of INVITE by default. The original dialog
module required dlg_manage() to be called to achieve that.
Once again – thanks for your help.
Cheers
Shane

Hi Shane,
Please make sure you create a new transaction using t_newtran() if t_check_trans() fails. Dialog will not be tracked if there is no transaction.

Hi Jason,
Appreciate the reply. Below is my log file for processing initial INVITE (I will send the config
file privately so you can match up line numbers). Note that as you may have noticed from a previous posting, I have modified ims_charging module to use standard usrloc module. I know this would normally mean people’s interest in helping tends to wane but
the changes weren’t major and the area of checking the dialog exists in the Ro_CCR() is independent of the usrloc changes which only kick in later in the process. So hoping you are willing to give it a quick look even under these circumstances. Currently
I can’t see how it works for you guys unless dialog_ng creates an initial dialog before the t_relay() call when the flag is set – which would be different behaviour to standard dialog module.
Cheers

Shane,
Just looking at your config I see you have already set the flag. Can you perhaps send me a log file and I will take a look for you. This is exactly how we, and others (ng voice)
use it in our IMS setups so it should work....
Cheers

Hi Shane,
dialog_ng started as a prototype by us quite a while ago to form the basis of dialogs in our IMS implementation using Kamailio. We took quite a lot from the existing dialog module
at the time and then built the additional functionality on top. There were some things (like dlg_manage) that we did not move across.... and this is bad.... so I apologise.
Right now to get a dialog recorded you need to define a flag in the modparam:
modparam("dialog_ng", "dlg_flag", 10)
And then when you want to track a dlg do something like:
if (is_method("INVITE")) {
setflag(10);
...
}
We have had a lot of other work to focus on and haven't spent too much time on dialog_ng but we will certainly put some effort into making it easier to use and more complete.
Cheers

Thanks Daniel - that clarity helps. Apologies if I should have been able to glean that from the docs - I just didn't see it in my reading. FYI, dialog-ng has deprecated the dlg_mange() function.
Can anybody who has used or involved in writing the dialog-ng module shed some light on what the new mechanism is for creating an early dialog structure?
Cheers and thanks
Shane

Hello,
I haven't used the dialog_ng module, but (as expected based on the
dialog module) if you only set the FLT_DIALOG flag, then the dialog is
created when calling t_relay(). The dialog module has dlg_manage()
function which creates the dialog immediately, maybe that's in dialog_ng
as well.
Cheers,
Daniel
