Chapter 4-Additional Conferencing Information

•Media Encryption for ISDN/PSTN participants is implemented in RMX systems with MPM+ and MPMx cards.

•Conference level encryption must be set in the Profile, and cannot be changed once the conference is running.

•If an endpoint connected to an encrypted conference stops encrypting its media, it is disconnected from the conference.

•In Cascaded conferences, the link between the cascaded conferences must be encrypted in order to encrypt the conferences.

•Media Encryption for ISDN/PSTN (H.320) participants is not supported in cascaded conferences.

•The recording link can be encrypted when recording from an encrypted conference to the RSS that is set to encryption. For more information, see "Recording Link Encryption” on page 14-7.

•Encryption of SIP Media is supported using SRTP (Secured Real-time Transport Protocol) and the AES key exchange method.

•Encryption of SIP Media requires the encryption of SIP signaling - TLS Transport Layer must be used.

•Encryption of SIP Media is supported in CP and VSW conferences.

—All media channels are encrypted: video, audio and FECC.

—Encryption of SIP Media is available only in MPM+ and MPMx Card Configuration Modes.

—RMX SRTP implementation complies with Microsoft SRTP implementation.

—LPR is not supported with SRTP.

—The ENABLE_SIRENLPR_SIP_ENCRYPTION System Flag enables the SirenLPR audio algorithm when using encryption with the SIP protocol. The default value of this flag is NO meaning SirenLPR is disabled by default for SIP participants in an encrypted conference. To enable SirenLPR the System Flag must be added to system.cfg and its value set to YES.

—The SEND_SRTP_MKI System Flag enables or disables the inclusion of the MKI field in SRTP packets sent by the RMX. The default value of the flag is YES. Add the flag to system.cfg and set its value set to NO to disable the inclusion of the MKI field in SRTP packets sent by the RMX when using endpoints that cannot decrypt SRTP-based audio and video streams if the MKI (Master Key Identifier) field is included in SRTP packets sent by the RMX. This System Flag should not be set to NO when HDX endpoints, Microsoft Office Communicator and Lync Clients. For more information, see "Modifying System Flags” on page 22-1.

Mixing Encrypted and Non-encrypted Endpoints in one Conference

Mixing encrypted and non-encrypted endpoints in one conference is possible, based on the Encryption option “Encrypt When Possible” in the Conference Profile - Advance dialog box. The behavior is different for H.323/SIP and ISDN participants.

In versions prior to version 7.6.1, this behavior is based on the setting of the system flag
