UC Video Call - FAQ

Use our frequently asked questions to find out more about our product.

How do you install the control?

You can read the instructions in: DVSinchClientInstallation

How secure is the control?

The control is based on Sinch SDK, which uses the WebRTC protocol and performs encrypted SSL/HTTPS requests. You can read further information at https://www.sinch.com/customer-service/frequently-asked-questions/

Regarding security considerations, the WebRTC protocol, mentions the following in its Section 6.5

"All media channels MUST be secured via SRTP and SRTCP. Media traffic MUST NOT be sent over plain (unencrypted) RTP or RTCP; that is, implementations MUST NOT negotiate cipher suites with NULL encryption modes. DTLS-SRTP MUST be offered for every media channel."

So, the call stream is encrypted by using Datagram Transport Layer Security (DTLS), which is a communications protocol that provides security for datagram-based applications by allowing them to communicate in a way that is designed to prevent eavesdropping, tampering, or message forgery.

You can visualize the WebRTC stack in the following diagram:
