Use the Secure Rtp RTCP window to specify a Secure Real-Time Control Protocol (RTCP) crypto-suite to use in a specified Packet Service Profile (PSP). SRTP is an IETF cryptographic protocol used to provide secure communications over untrusted networks as described in RFC 3711. SRTP provides confidentiality, message authentication and replay protection to Internet media traffic such as audio and video. The SBC Core supports Secure RTP and its associated secure real-time transport control protocol (Secure RTCP) for IPv4/IPv6 addressing for both audio and video streams. In addition to specifying the crypto-suite profile on this window, use the Flags window to specify additional SRTP parameters for the specified PSP.
Within a Packet Service Profile (PSP), configure either DTLS (Datagram Transport Layer Security) parameters or SRTP (Secure Real-Time Transport Protocol) parameters, but not both.
To View and Edit the Secure Rtp RTCP Crypto-Suite Profile
- On the SBC main screen, go to Configuration > Profile Management > Category: Media Profiles > Packet Service Profile > Secure Rtp RTCP.
Select a Packet Service Profile to configure from the drop-down list. The Secure Rtp RTCP window is displayed.
- Select a Crypto Suite Profile name from the list. The list contains names of configured Crypto Suite profiles. Refer to Security Profiles - Crypto Suite Profile for more information.
- Click Save.
