ZRTP, a cryptographic key-agreement protocol using Secure Real-time Transport Protocol for encryption
The recent publication of new VoIP encryption standards built into the protocol, such as ZRTP and SRTP, allow the VoIP client to run without the VPN overhead, integrating with standard features of VoIP PBX without having to manage both the VPN gateway and the PBX.
ZRTP can be used with any signaling protocol, including SIP, H.323, Jingle, and distributed hash table systems.
