mediaproxy is an OpenSER module that is designed to allow automatic NAT traversal for the majority of existing SIP clients. This means that there will be no need to configure anything in particular on the NAT box to allow these clients to work behind NAT when using the mediaproxy module. An alternative solution for NAT traversal is nathelper module.
To run mediaproxy module you need an external RTP proxy server called OpenSER MediaProxy (available from http://mediaproxy.ag-projects.com/).
