Re: [Sipping] draft-rosenberg-sipping-acr-code-00.txt

Since the draft defines a new SIP response code, I believe it would  
need to be progressed through the SIP working group as a standards- 
track document.

Do we have a consensus in SIPPING on the fundamental requirements and  
the general approach? If so, we can forward this work to SIP for  
completion.
