    IANA Registration of Enumservices for Voice and Video Messaging

Status of This Memo

   This document specifies an Internet standards track protocol for the
   Internet community, and requests discussion and suggestions for
   improvements.  Please refer to the current edition of the "Internet
   Official Protocol Standards" (STD 1) for the standardization state
   and status of this protocol.  Distribution of this memo is unlimited.

Abstract

   This document registers the Enumservice named "vmsg", which is used
   to facilitate the real-time routing of voice, video, and unified
   communications to a messaging system.  This vmsg Enumservice
   registers three Enumservice types: "voicemsg", "videomsg", and
   "unifmsg".  Each type also registers the subtypes "sip", "sips",
   "http", and "https", as well as the subtype "tel" for the "voicemsg"
   type.
