[SR-Users] Dialogs not deleted on BYE

[Shane Harrison]

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

Mar 16 22:43:42 hh-rcs-sipproxy3 /usr/sbin/kamailio[15484]: DEBUG: tm [t_lookup.c:1373]: t_newtran(): DEBUG: t_newtran: msg id=16 , global msg id=15 , T on entrance=(nil)

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
