The Media Gateway Unit comes fully functioning, with a bootable Linux Operating System and with an operable version of the MGU software, which will be started at power on. It may be necessary to upgrade the MGU to a newer version. This MGU firmware update/upgrade has to be initiated manually.
For more information, see the installation instructions for INSTALLING AND CONFIGURING MIVOICE MX-ONE or see the installation instructions for UPGRADING AND UPDATING.
When the firmware has been updated or upgraded, the Media Gateway is restarted automatically. After restart, the new firmware is installed on the Media Gateway.
