Description
Your phone supports RTP encryption via SRTP. If you want to encrypt your outgoing audio (RTP) stream, this option must be “on”. Both parties have to enable the RTP Encryption option to establish an SRTP call. RTP encryption has nothing to do with SSL/TLS. The keys are sent in the SDP part of SIP messages. Certificates are not used for this.
