Parameter Description Configuration Method
SRTP
Specify the SRTP type.
The supported types are as
follows:
• Disabled—the encrypted calls
are not supported.
• Optional—both encrypted
and unencrypted calls are
supported. Secure calls are
supported only if the far end
supports encryption.
• Compulsory—unencrypted
calls are not supported.
Default: Disabled.
Web user interface
When SRTP is enabled on both sites, RTP streams will be encrypted, and a lock icon appears on the
monitor of each system after successful negotiation.
H.235
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:
Remote\Local Compulsory Optional Disabled
Compulsory H.235 Call H.235 Call Fail to establish a call
Optional H.235 Call H.235 Call RTP Call
Disabled Fail to establish a call RTP Call RTP Call
