MX-ONE Media Gateway

The Media Gateway using the MGU provides VoIP security according to the SRTP protocol (RFC 3711), using data flow encryption with AES in Counter Mode (CM) and authentication with HMAC-SHA1.

To manage the Media Gateway using the Command Line Interface, SSH is the preferred solution. The Media Gateway can thus for trouble-shooting activities be logged on using SSH. To increase security, direct root access is disabled by default. If the system administrator needs to carry out some task that requires root access, the administrator first needs to log on as a non-root administrator, and then require the system to grant root privilege by performing a second authentication procedure.

See the Media Gateway Unit description for details.
