WebRTC Media Streaming in FS: SRTP

Irrespectively of which session signaling protocol is used by WebRTC clients (SIP or Verto), their media streams will always be encrypted as mandated by WebRTC specs. That would be Secure RTP (SRTP), with encryption keys sent via DTLS. Actually inside FreeSWITCH the same module and source code will be used to encrypt and serve media streams to both kind of WebRTC clients.
As seen previously, WebRTC mandates how to stream and encrypt media, leaving the session protocol to the whim of the application implementer.
