Technical Summary

   The Third Generation Partnership Project (3GPP) has identified cases
   where different SIP private header extensions referred to as "P-"
   header fields, and defined in RFC 7315, need to be included in SIP
   requests and responses currently not allowed according to RFC 7315.
   This document updates RFC 7315, in order to allow inclusion of the
   affected "P-" header fields in such requests and responses.

   This document also makes updates for RFC 7315 in order to fix
   misalignments that occurred when RFC 3455 was updated and obsoleted
   by RFC 7315.
