System Administration - File Upload

 This section provides the information on how to upload application and license files to SBC.

File Upload

The File Upload tool allows you to upload application files to SBC. These files must be available in your local drive for easy access and faster upload. You can upload the following files:

• SBC Application Files (.template, .tar.gz, .md5, .cli, .qcow2 and .signature files): Specifies the complete SBC Application files. These are used to upgrade or to perform a fresh SBC installation.
• SBC Back-up Files (.tar.gz): Specifies the back-up files which can be uploaded to SBC from an external source.
• License Files (.pem, .xml, and .p12 files): Specifies the list of SBC Licenses.

• Announcement Files (.wav files): Specifies short audio files used when SBC sends the 183 Session Progress in SIP call.

• Certificate Files (.der files): Files with .der extension are digital certificate files created in the Distinguished Encoding Rules (DER) format. It contains a binary representation of the certificate, and is commonly used for storing X.509v3 certificates in public key cryptography.

  Note

  The SBC allows you to upload only the allowed filed types, and also places restrictions on the file names. Such measures are implemented to secure the SBC from malicious file uploads. To know more about the allowed file types and file name restrictions, see the Restrictions on File Properties section.
