This will open up the User Manager dialog box. The User Manager will display all the Users and Groups configured. Click on the Groups tab and the Group ID can be obtained there. |
Mount Directory - Enter the path to where the audio files are located. This path includes the path to the share created plus any directories within that share required to get to the audio files. In this example the Mount Point field is /home/dialogic/shares and the directory is labeled announcements. |
Refer to the NFS Location object for information on this object.
From SD Card
Right click on the Files object and select New Media File Location. The Media File Location object is a parent or container object and where to retrieve the audio files is configured under this object. Refer to the Media File Location topic for more information on this object.
Right click on the Media File Location object and select New Local Location. The Local Location object is displayed below, enter the information in the fields as described below.
Field/Description |

Download Announcement Files to IMG 2020
At this point, the IMG 2020 is configured to either retrieve the audio files from the configured NFS Server or the SD Card. Click back on either the NFS Location or Local Location object and verify the Location Status field is displaying Available. Refer to screen capture below.
