This article introduces the Ozeki Phone System XE Encryption tool, a great and comfortable option to encrypt or decrypt your files with public or private keys of RSA algorithm. With this tool you are able to browse to your files and RSA keys and create new encrypted or decrypted files with the help of these keys. It is useful when you set up the encryption security in Ozeki Phone System XE for call recordings and you want to decrypt these recordings.
If you had set up a call recording rule with file encryption, then you had to get the private key of the RSA key pair.
You will ned this key to decrypt your recorded call.
Open your Ozeki Phone System XE with your personal account (username and password), then find the call history menu option to download your former telephone converstations. Select the PBX features tab on the top of the screen, then the Call history menu option.
