Re: [SR-Users] Using dialog_ng

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

Hi all,

I think the lack of response to my previous thread is probably because it was too complicated. I have now narrowed my problem down after further archive readings .

I am trying to use the dialog_ng module along with the ims_charging_module. Upon reception of an INVITE, a call to the Ro_CCR() from the request_route script is made. That function does a check that the dialog record exists (binds to dialog module and does a "get_dlg(msg)" call) - this fails i.e. dialog is not found.

Running kamailio 4.2.2 and relevant sections of kamailio.cfg are: modparam("dialog_ng", "dlg_flag", FLT_DIALOG) modparam("dialog_ng", "timeout_avp", "$avp(DLG_TIMEOUT_AVP)") modparam("dialog_ng", "detect_spirals", 1) modparam("dialog_ng", "profiles_no_value", "orig ; term")

request_route { # NAT detection route(NATDETECT);

    # Set DLG flag to track dialogs using dialog2
    if (!is_method("REGISTER|SUBSCRIBE"))
            setflag(FLT_DIALOG);

    # handle requests within SIP dialogs
    route(WITHINDLG);

    ### only initial requests (no To tag)

    # CANCEL processing
    if (is_method("CANCEL"))
    {
            if (t_check_trans())
                    t_relay();
            exit;
    }

    t_check_trans();

    if (is_method("INVITE"))
    {
            set_dlg_profile("orig");
           Ro_CCR("CHARGING_CCR_REPLY", "orig", "SCUR", "", "30","CCR_location");
   }

So my question is, "should the above logic create a dialog record on the initial INVITE?" and if yes then "what possible reasons might there be for the Ro_CCR() function not be able to detect it exists?"
