NAT Traversal Practices for Client-Server SIP
RFC 6314, “NAT Traversal Practices for Client-Server SIP”, is an Informational document published in July 2011 by C. Boulton, J. Rosenberg, G. Camarillo, F. Audet. The canonical text is published by the RFC Editor.
Abstract
Traversal of the Session Initiation Protocol (SIP) and the sessions it establishes through Network Address Translators (NATs) is a complex problem. Currently, there are many deployment scenarios and traversal mechanisms for media traffic. This document provides concrete recommendations and a unified method for NAT traversal as well as documents corresponding flows. This document is not an Internet Standards Track specification; it is published for informational purposes.
