[reSIProcate] Dum multi-call design

[Derek MacDonald]

If you are canceling an outgoing call where there hasn't been a prov.
response you should call AppDialogSet::end().  If there have been
provisional responses and you wish to cancel a particular dialog, using the
InviteSession is the way to go.

 

AppDialogs are created and destroyed when a SIP dialog is created and
destroyed; you should use AppDialogSet::createAppDialog.  There is no
destroy() method as there is no use case yet for sharing AppDialogs.

Hi,

 

I have been thinking about this implementation and am confused on exactly
how to manage the AppDialogSet and AppDialog pointers.

 

The ultimate goal is to be able to cancel an outbound invite if there is no
response from the UAS.  When creating an Invite with
DUM::makeInviteSession(.,myAppDialogSet), I clearly have a way of mapping a
user-defined key (integer or whatever) to myAppDialogSet.  I can use this
user-defined key to get a pointer to myAppDialogSet for this call.  Where I
am confused is what I really want is a myAppDialog pointer to call
myAppDialog->getInviteSession().  To do this I need a pointer to
myAppDialog.  I suppose this could be done in
myAppDialogSet::createAppDialog() (maybe this won't work; when does a
AppDialog get created?) by adding another mapping from a user-defined key to
myAppDialog.  If I do this, how do I know when myAppDialog is deleted by
resip?  AppDialogSet gives a virtual destroy() method, but AppDialog does
not.

 

Thanks,

 

-Justin

Hi Scott,

Thanks for the pointers. The website link was helpful since that site
contains quite a lot of other useful documentation also. 

i also understand what you meant by not getting response from the UAS side.
i was expecting to get the OnFailure or OnTerminated Callback since my uas
wasnt setup to send any response, but never got it. i guess the app needs to
maintain the timer for such cases and send the cancel.
