[SR-Users] Using dialog_ng

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?"
