Hi Christer,
 
It would be easier for UAS to tell if it sends non-100 1xx response
creating early-dialog before sending 199.
However, it's a little bit difficult from UAC's perspective, since the
non-100 1xx response might not be reliable.
 
If UAC does not get , say 180, but get 199 first, it looks like it does
not make any sense.
 
One option is to mandate usage of 100rel, which might be too strict for
this draft.
 
Regards,
-Rockson

Hi,
 
You wouldn't send a 199 unless you have already sent a non-100 1xx
response, so the early dialog has already been created.

Hi,
 

one questions on this draft.
 

Since RFC3261 says, non-100 1xx response for INVITE cause early-dialog
creation.
does this draft will normativly change the criteria, excluding 199?
 

If, the answer is Yes, I think it need be stated explicitly in the
draft.
 
 
 
thanks
 

Regards,
-Rockson
