Field/Option Description
Encryption Select the Encryption option for the conference:
• Encrypt All - Encryption is enabled for the conference and all
conference participants must be encrypted.
• No Encryption - Encryption is disabled for the conference.
• Encrypt when Possible - enables the negotiation between the
MCU and the endpoints and let the MCU connect the participants
according to their capabilities, where encryption is the preferred
setting. For connection guidelines see "Mixing Encrypted and
Non-encrypted Endpoints in one Conference” on page 4-42.
For more information, see "Media Encryption” on page 4-41.
LPR When selected (default for CP conferences), Lost Packet Recovery
creates additional packets that contain recovery information used to
reconstruct packets that are lost during transmission.
LPR check box is automatically cleared if High Definition Video
Switching is selected, but can be selected if required. For more
information, see "Packet Loss Compensation (LPR and DBA) AVC
CP Conferences” on page 4-49.
Auto Terminate When selected (default), the conference automatically ends when the
termination conditions are met:
Before First Joins — No participant has connected to a conference
during the n minutes after it started. Default idle time is 10 minutes.
At the End - After Last Quits — All the participants have
disconnected from the conference and the conference is idle (empty)
for the predefined time period. Default idle time is 1 minute.
At the End - When Last Participant Remains — Only one
participant is still connected to the conference for the predefined time
period (excluding the recording link which is not considered a
participant when this option is selected). This option should be
selected when defining a Profile that will be used for Gateway Calls
and you want to ensure that the call is automatically terminated when
only one participant is connected. Default idle time is 1 minute.
Note: The selection of this option is automatically cleared and
disabled when the Operator Conference option is selected. The
Operator conference cannot automatically end unless it is terminated
by the Collaboration Server User.
