IANA Registration of Enumservices for Voice and Video Messaging
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. [STANDARDS-TRACK]
