	`8€`Configurable TiVi SIP client Includes passive ZRTP license `0€`3-day trial business license of ZRTP `143€`Economy license of ZRTP `278€`Business license of ZRTP ZRTP is described in the Internet-Draft as a "key agreement protocol which performs Diffie-Hellman key exchange during call setup in-band in the Real-time Transport Protocol (RTP) media stream which has been established using some other signaling protocol such as Session Initiation Protocol (SIP). This generates a shared secret which is then used to generate keys and salt for a Secure RTP (SRTP) session." One of ZRTP's features is that it does not rely on SIP signaling for the key management, or on any servers at all. It supports opportunistic encryption by auto-sensing if the other VoIP client supports ZRTP.
