NAT and Firewall Scenarios and Solutions for SIP

Status: Reverted to individual item, version -01

Summary: This document contains a set of examples about how to establish sessions through Network Address Translators (NATs) using the Session Initiation Protocol (SIP). NAT traversal for SIP is accomplished using Interactive Connectivity Establishment (ICE), which allows the media streams to work, in addition to the SIP extension for symmetric response routing, which allows SIP itself to flow through NAT. The examples cover a range of network topologies and use cases. This variability helps to demonstrate that the ICE methodology always works, and that a common client algorithm, independent of the network topology and deployment configuration, results in the best connectivity.
