[SR-Users] Dialogs not deleted on BYE

[Shane Harrison]

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
