Summary: missing callback from tm->dialog module for 200ok (reINVITE)

Initial Comment:
It seems that there are no callbacks into the dialog module from the tm module for 200ok for in call transactions (reINVITE).
The callback mechanism is working ok for the 200ok of the initial INVITE, but not for subsequent reINVITES.

Hi Ovidiu,

yes, the replies for on-dialog requests were on purpose let aside as they
were complicated things (as code and as logic) too much and I saw no usage
case for them..

The problem at logical case is that you the callbacks will be called
several time for the same event, but once for the initial request (when the
dialog is created) and later for the on-dialog requests and this might get
confusing ......

do you have a usage case for that?

This seems to be a problem related to all responses to in-dialog requests.

It seems that the first INVITE is handled by dlg_onreq() and here the
following callbacks are registered back with the transaction:
TMCB_RESPONSE_OUT|TMCB_TRANS_DELETED|TMCB_RESPONSE_FWDED.

reINVITEs are handled by the dlg_onroute() and no callbacks are registered
for subsequent responses (for the new transaction).  Somehow, while
handling the reINVITE inside dlg_onroute(), the callbacks for
TMCB_RESPONSE_OUT|TMCB_TRANS_DELETED|TMCB_RESPONSE_FWDED should be
registered.
