Enabling Encryption for Videoconferences

About this task
The system can secure videoconference sessions via encrypted connections, in both point-to-point calls
and videoconferences, as follows:
• For SIP connections, you can encrypt the actual media of SIP connections via SRTP.
Secure Real-time Transport Protocol (SRTP) adds security to the standard RTP protocol, which is
used to send video and audio data between devices in SIP calls using TLS. It offers security via
encrypting, authenticating and ensuring message integrity.
• For H.323 connections, encryption is enabled via H.235.
H.235 is the protocol used to authenticate trusted H.323 endpoints and encrypt the media stream
during meetings.
Configure settings for securing calls as described in the procedure below. You can have up to three
remote encrypted participants in a videoconference.
You can do this procedure from the endpoint itself or from the XT Server web interface. If you are not
connecting a monitor to the XT Server, you can perform this procedure from the web only.
Important:
Using encryption is subject to local regulation. In some countries it is restricted or limited for usage.
For more information, consult your local reseller.
