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.

  • In FW Version 6 the default value is "off", you have to switch it to "on" in order to have SRTP enabled. Then, a small lock sign is shown on the display if STRP is active during a call, this means that an SRTP encrypted call is currently taking place.
  • In FW Version 7 the default value is "on". In order to obtain full security SIP call you have to use TLS as well. Then, a small lock sign is shown on the display which means that an secure SIP call is currently taking place (SIP secured + RTP encrypred).
