Thanks Daniel,
From the request_route block I call the ims_charging
module function Ro_CCR(). This is non-blocking and one of the parameters in the call is
the route block to be called ( e.g. CHARGING_CCR_REPLY ) when the response to the charging
request is obtained. Looking at the code, the Ro_CCR() function does a t_suspend() and
then the ims_charging module does a t_continue() when the response is received. Then the
specified routing block is called and processing of the INVITE continues.
route[CHARGING_CCR_REPLY] {
xlog("L_DBG","cca_return code is $avp(s:cca_return_code)\n");
switch ($avp(s:cca_return_code)) {
case 1: #success
route(LOCATION);
route(RELAY);
break;
.....
}
It appears that the RR parameter that is added during the request_route processing (via
dialog tracking) is no longer there when the INVITE continues being processed in the
CHARGING_CCR_REPLY route block. Is that what you would expect? Any pointers to
solutions?
Hope that answers your question.
Cheers
Shane

In what callback do you need it?
Cheers,

Thanks Daniel. Yes I am using the ims_charging module
hence the need for
the dialoguing module.
I have confirmed that the dialog_id (DID) is added if I t_relay() the INVITE
in the request_route. Hence dialog_ng is adding the parameter to the
record_route when it creates a new_dialog. It is however lost once I exit
from request_route.
How do I ensure the RR parameter gets added when I resume processing the
INVITE in the callback route block?
Cheers and thanks
Shane

Hello,
dialog_ng is more or less tailored for IMS modules, dialog module is
still in use and very actual.
If you are not using IMS module, you should try the dialog module. I
haven't seen any issues for it lately and if there are, they will get
fixed.
Cheers,
Daniel

Hi all,
Have found a few threads on this before which have clarified my
understanding a little but not yet presented me with a solution.
I am using dialog_ng. dlg_manage() is deprecated and as per the
documentation, I am simply setting a dialog flag early in the
request_route.
Kamctl dialog show does indeed show the dialogs are tracked, but they are
not destroyed on the receipt of the BYE. Dialog ref count remains at 2
and in state=4
Log shows the following

Looks to me as if fails to find a dialog match and actually creates a new
dialog.....
Dialog_ng only has one matching mode - DID, others have been deprecated.
I have captured the outgoing INVITE and there is no dialog_id parameter
added to the record_route. Is that causing my matching problem?
Record-Route:
<sip:64.208.160.211;transport=tcp;lr=on;ftag=5419eecb;nat=yes>
Record-Route: <sip:203.171.39.49:5061;transport=tls;lr=on>
Cheers
