RFC 2833 Session Agent Configuration
Session agents, used as a way to classify and act on a subset of a signaling interface’s traffic, also have rfc2833-mode and rfc2833-payload parameters. The configurations of these parameters overrides the configuration of the same-named parameters on the signaling interface where the session agent resides. You can set the rfc2833-mode parameter to none for a session agent to revert to the parent signaling interface’s two RFC 2833 settings.
