H.235 Encryption
H.235 system provides the identity authentication, the data encryption, and the integration. H.235 encrypts
the RTP during H.323 calls to avoid interception and eavesdropping.
The H.235 is supported by the systems. The parties participating in the call must enable H.235 feature
simultaneously. When this feature is enabled on both sites, the encryption type used in the session is
negotiated between the systems. The StarLeaf platform also supports H.235 encryption. After logging in to
the StarLeaf platform, you can use H.235 encryption.
Rules of H.235 security in H.323 calls are described as below:
