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.

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
