TANDBERG MSE 8510 You can, conference to either, force new ad hoc conferences to use encryption

You can configure the MCU to encrypt connections to and from H.323 and SIP endpoints.

The encryption technology that the MCU uses for encryption to and from H.323 endpoints is Advanced Encryption Standard (AES).

The encryption technology that the MCU uses for encryption to and from SIP endpoints is Secure Real-time Transport Protocol (SRTP).

To use encryption, you must have the Encryption feature key present on the MCU. For information about installing

feature keys, refer to Upgrading the firmware. To access encryption settings, go to .

Encryption is used where both devices in a call agree to use encryption; by default if one of the devices cannot use encryption (for example if SIP endpoint does not support SRTP), the MCU will allow the call to be unencrypted, unless the conference configuration dictates that encryption is Required. Where encryption is required, calls that cannot used encryption will not be allowed.

When encryption is in use to and from H.323 endpoints, the MCU will encrypt audio, video, and content media. It does not encrypt control or authentication information.

When encryption is in use to and from SIP endpoints, the MCU will encrypt audio and video media using SRTP. Control or authentication information can also be encrypted using TLS. For more information refer to Using encryption with SIP, below.

You can:

configure the MCU to advertise its ability to encrypt connections, such that it will use encryption if an H.323 endpoint can use AES encryption

configure the MCU to advertise its ability to encrypt connections, such that it will use encryption if a SIP endpoint can use SRTP encryption

configure the MCU so that the default encryption option for new conferences is either		or
. Be aware that anyone creating a new conference will be able to set the encryption setting for the
conference to either	or
force new ad hoc conferences to use encryption

Note that using encryption does not affect the number of ports that are available on the MCU.

Note that the MCU will not show thumbnail previews on the Conference participant page if encryption is required

for a conference. If you have the Show thumbnail images option selected on the page, thumbnail previews will be shown for conferences where encryption is optional and there are encrypted participants.
