The IMG 2020 can have Gateway functionality, Session Border Controller Functionality, or both. Using the IMG 2020 specifically as a Gateway requires a license to open various functions including SS7 Signaling, ISDN Signaling, and VoIP. The licenses are distributed by email when the product is purchased. Each license will unlock a different function and the licenses are sold in multiple increments to address each customer needs. After receiving the license, transfer the license using SFTP to the SD card or FTP server (whichever the system software file is loaded from). Click on the Physical Node IMG 2020 object. In the object page, click on the Download New License button. The license will automatically download to the IMG 2020 node.
