SRTP (Secure Real-Time Transport Protocol) in the Lotus Sametime Unified Telephony solution involves the coordination of SRTP implementation across multiple products. SRTP provides a framework for encryption and message authentication of RTP (Real-Time Transport Protocol) and RTCP (Real-Time Transport Control Protocol). Media encryption is entirely controlled by the media endpoints; the role of the Lotus Sametime Unified Telephony server is only to facilitate the negotiation of encryption parameters between the endpoints.
Encrypted media (SRTP) with the MIKEY (Multimedia Internet Keying) Profile 0 key management protocol is supported by the following:
OpenStage, optiPoint 410 S/420 S phone families, optiClient 130 S, and selected third-party SIP phones
Lotus Sametime Xpressions, R2 and later
Convergence SBCs (Session Border Controllers)
Connections between two Lotus Sametime Unified Telephony systems signaled over the SIP-Q interface
Connections between Lotus Sametime Unified Telephony and the , legacy system and later
Connections between Lotus Sametime Unified Telephony and the , V7 and later
In legacy system, the Lotus Sametime Video endpoints (Lotus Sametime Video VHD100, VHD400, VHD600), and later, will also support SRTP.
