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

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
