Downloading CDRs through SFTP
You can use SFTP (SSH File Transfer Protocol or Secure File Transfer Protocol) to access the CDR files that are locally stored on the device (see Storing CDRs Locally on the Device). The locally stored CDRs are located in the /cdr folder.
As this is a secure connection, the SFTP client needs to authenticate itself with the device (SFTP server). The device performs standard user authentication, where you can set it up to check the user's credentials in the Local Users table (see Configuring Management User Accounts) or with a remote authentication server.
You can access the /cdr folder only if you're an Administrator or a Security Administrator user.
