You can use the Advanced Encryption Standard (AES) algorithm for encrypting your voice and video calls made from the codec. If you enable AES encryption, it encrypts both audio and video data simultaneously.
Procedure
On the Settings menu, go to Security > SIP Media Security.
To use AES encryption, select the option corresponding to your security requirements.
To disable AES encryption, select the Plaintext (unencrypted) check box.
For example, you can disable AES encryption for interoperability reasons or troubleshooting to be able to capture network packets.
