SIP URI Service Discovery using DNS-SD
Jae Seung Lee, Henning G. Schulzrinne, Zoran Despotovic, Wolfgang Kellerer · 2008
This document describes how to use the DNS-based Service Discovery (DNS-SD), better known as Apple Bonjour, for advertising Session Initiation Protocol (SIP) URIs in local area networks. Using this mechanism, a SIP user agent (UA) can communicate with another UA even when no SIP registrar is available, as in a wireless ad-hoc network for example.
