9.2.3 Enabling H.235 Encryption

The H.235 encryption encrypts media streams using a negotiated encryption algorithm and key.
The encrypted media streams can be decrypted with the negotiated algorithm and key, thus
preventing unauthorized access.
Context
An IP network is not a quality-guaranteed or secure network. Encrypting the media streams
strengthens the security of video communications. To enable media stream encryption, both
parties in communication need to support the encryption functions.
Procedure
Step 1 Choose Settings > Security > Encryption Policy to select an H.235 encryption policy.
