Ballot Text

Technical Summary

   The SIP Reason Header Field as defined in RFC 3326 allows only one
   Reason value per protocol value.  Experience with more recently
   defined protocols shows it is useful to allow multiple values with
   the same protocol value.  This update to RFC 3326 allows multiple
   values for an indicated registered protocol when that protocol
   defines what the presence of multiple values means.

Working Group Summary

The consensus for this document within the workgroup was very strong.  A relatively large cross section of the work group read the doc and believed it was ready to publish,  

Document Quality

There are entities who are planning implementations but the shepherd is unaware of existing implementations.  However, this document is required for recent developments in STIR, which has wide deployment, and we expect quite a few implementations shortly.  

Personnel

Brian Rosen is the Document Shepherd.
