However, that's not the use case that is commonly cited as causing the  
SIP interaction problem. If it were, we'd probably have come to a more  
reasonable conclusion on SIP early media.

I'd argue that we moved into the topic of "accommodating broken  
billing/charging models" by the concessions we made with our flawed  
and mostly dysfunctional early-media model.

It's broken now, it has always been broken, and I predict it will  
continue to be broken for the future of SIP 2.0.
