Introduction

Some computer networks are secured by using a lot of tools that include VoIP communication blocking. These security settings are mainly set within the firewall and others can be separate settings or even security programs or virus scanners.

When you want to initiate a VoIP call into a network that is behind a firewall, you can use some standard NAT traversal technologies or VoIP tunneling.

Tunneling is the transmission of data intended for use only within a private, usually corporate network through a public network in such a way that the routing nodes in the public network are unaware that the transmission is part of a private network. Tunneling is generally done by encapsulating the private network data and protocol information within the public network transmission units so that the private network protocol information appears to the public network as data.
