43.2.2 Obtaining License Key for Feature Upgrade
Before you can install a new License Key, you need to obtain a License Key file for your
device with the required features from your AudioCodes representative. The License Key is
an encrypted key in string format that is associated with the device's serial number ("S/N")
and supplied in a text-based file. If you need a License Key for more than one device, the
License Key file can include multiple License Keys (see figure below). In such cases, each
License Key in the file is associated with a unique serial number identifying the specific
device. When loading such a License Key file, the device installs only the License Key that
is associated with its serial number.

 To obtain a License Key:
1. Open the Device Information page (see ''Viewing Device Information'' on page 797)
and make a note of the device's MAC address and/or serial number:
• 'MAC Address' field displays the MAC address.
• 'Serial Number' field displays the serial number.
2. If you need a License Key for more than one device, repeat Step 1 for each device.
3. Send the MAC address and/or serial number to your AudioCodes representative when
requesting the required License Key.
4. When you receive the new License Key file, check the file as follows:
a. Open the file with any text-based program such as Notepad.
b. Verify that the first line displays "[LicenseKeys]".
c. Verify that the file contains one or more lines in the following format:
"S/N<serial number> = <License Key string>"
For example: "S/N370604 = jCx6r5tovCIKaBBbhPtT53Yj..."
d. Verify that the "S/N" value reflects the serial number of your device. If you have
multiple License Keys, ensure that each "S/N" value corresponds to a device.
Warning: Do not modify the contents of the License Key file.
5. Install the License Key on the device, as described in ''Installing the License Key'' on
page 764.
43.2.3 Installing the License Key
