I would argue that, if we don't understand what copying an InviteSession should mean, we should just remove the code. Just my 2 cents.Best regards,Byron CampenNot sure where it would be copied, but we would get a crash in the InviteSession destructor when resiprocate would shutdown if it wasn't an auto_pointer

When is an InviteSession ever copied? I don't think this is a problem.

Hi Scott,
I found an issue with the implementation: the elements of mNITQueue are not correctly duplicated on an InviteSession copy as currently implemented (my bad, not yours).
I changed it to be a queue of shared rather than raw pointers.

Thanks Kobi! I think this patch is a good idea - I've had to do the same thing at the app level in many of the applications I've created.
I've taken a look at the patch and have made some modifications to my local copy - I'll give others a few days to digest and make comments, then I'll commit it. Here are the changes I've made so far:
1. Removed use of the resip Fifo to store the queued NITs and replaced this with an STL queue - the FIFO classes uses Mutex's that are just unneeded overhead.
2. In an attempt to make things a little cleaner. I renamed the checkNITQueue fn to nitComplete - this fn now sets the state to completed and checks the queue. This new fn is called in dispatchInfo, dispatchMessage on responses and on refer responses.
3. As a consequence of 2 - removed the checkNITQueue call from Dialog.cxx, when receiving a response to INFO or MESSAGE NITs.
I've attached a new version of the patch.
Thanks,
Scott
