Media Encryption (AVC Only)
Encryption is available at the conference and participant levels, based on AES 128
(Advanced Encryption Standard) and is fully H.233/H.234 compliant and the Encryption
Key exchange DH 1024-bit (Diffie-Hellman) standards.
Media Encryption Guidelines
• Encryption is not available in all countries and it is enabled in the MCU license. Contact
Polycom Support to enable it.
• Media encryption is not supported in SVC Conferencing Mode.
• Endpoints must support both AES 128 encryption and DH 1024 key exchange
standards which are compliant with H.235 (H.323) to encrypt and to join an encrypted
conference.
• The encryption mode of the endpoints is not automatically recognized, therefore the
encryption mode must be set for the conference or the participants (when defined).
