Version 8.1 Detailed Description - New Features SIP Call Disconnect After Abnormal Call Termination When an abnormal disconnection of SIP endpoints occurs because of network problems or client application failures, SIP endpoints remain connected to the conference causing connection disruptions. For example, the video freezes in the layout or blocks content for SIP endpoints when a quick re-connection is performed. It can take several minutes to detect the SIP endpoint disconnection using the SIP standard behavior. In a normal SIP video call, audio and video (RTP and RTCP) messages are sent from the endpoints to the MCU to detect the signaling of connected endpoints. Conversely, SVC endpoints might not send video RTP messages to the MCU when a participant is not displayed in the video layout of any of the participants in the conference. For SVC endpoints, the MCU will only verify audio RTP and RTCP messages and video RTCP messages. Video RTP messages will not be checked. To detect the disconnection of SIP endpoints in a reasonable amount of time, a new system flag can be defined to specify the amount of time that the MCU should wait for an RTCP or RTP message from the SIP endpoint before the endpoint starts the disconnection process. The system default value is automatically set to 20 seconds. The system flag, DETECT_SIP_EP_DISCONNECT _TIMER, contains the amount of time in seconds to wait for an RTCP or RTP message to be received from the endpoint. When the time that was set in the system flag has elapsed and no RTCP or RTP audio or video message has been received on either the audio or the video channel, the MCU disconnects the SIP endpoint from the conference. A CDR event record is created with a Call Disconnection Cause of SIP remote stopped responding. The Microsoft Lync add-in endpoint opens audio and content channels. Lync endpoints can send RTCP/RTP messages and empty RTP audio messages. When the time that was set in the system flag has elapsed and no RTCP or RTP message has been received on the audio channel, the MCU disconnects the endpoint from the conference. SIP audio only endpoints use the audio channel only. When the time that was set in the system flag has elapsed and no RTCP or RTP message has been received on the audio channel, the MCU disconnects the SIP audio endpoint from the conference. Configuring the System Flag When you want to change the system default value of 20 seconds, the system flag, DETECT_SIP_EP_DISCONNECT_TIMER, can be manually added to the System Flags configuration to detect the disconnection of SIP endpoints. For more information see the Polycom RealPresence Collaboration Server 800s Administrator s Guide, "Manually Adding and Deleting System Flags on page 22-19. The value range is from 0 to 300 seconds. When the value is set between 0 and 14, the feature is disabled and SIP endpoints are not detected for disconnection. When the value is set between 15 and 300, the feature is enabled. Polycom, Inc. 25

RealPresence Collaboration Server 800s Virtual Edition Release Notes - Version 8.1 Sending Text Messages to All Participants using Message Overlay Message Overlay enables the operator or administrator to send text messages to all participants during an ongoing conference. Sending text messages using the Message Overlay options can be defined in the Conference Profile (CP AVC-based) or during the ongoing conference. The text message is seen as part of the participant s video layout on the endpoint screen or desktop display. Message Overlay Guidelines Sending text messages using the Message Overlay options is available only in CP AVC-based conferences. Changes to the Message Overlay display characteristics (position, size, color and speed) are immediately visible to all participants. Changes to the Message Overlay Content are immediately visible to all participants. When there is a current Message Overlay: The current message is stopped immediately. The Display Repetition count is reset to 1. The new message Content is displayed <Display Repetition> times or until it is stopped and replaced by another Content change. 26 Polycom, Inc.

Version 8.1 Detailed Description - New Features Enabling, Disabling and Modifying Message Overlay Display in the Conference Profile Sending text messages to all conference participants using the Message Overlay options can be enabled, disabled and modified using the New Profile - Message Overlay tab.

RealPresence Collaboration Server 800s Virtual Edition Release Notes - Version 8.1 Terminate Conference after Chairperson Drops Terminate Conference after Chairperson Drops allows a conference to be terminated after the chairperson leaves. When the chairperson leaves, the Chairperson Has Left IVR message is played to all participants, at which point the conference terminates. This way an operator does not need to monitor a conference to know when to terminate it manually. In previous versions similar functionality was provided by the TERMINATE_CONF_AFTER_CHAIR_DROPPED flag. This flag is no longer in use. Now this functionality is set on a per conference basis. The Chairperson can be either an AVC-enabled or SVC-enabled endpoint. If there is a single chairperson in the conference who is changed to a regular participant the conference will be terminated as if the chairperson left. If there is more than one chairperson then changing one chairperson to a regular participant will not terminate the conference. It is therefore recommended that before changing a single chairperson to regular participant, another participant first be changed to chairperson. To set a conference to terminate once the chairperson has left: 1 In a new or existing profile, click the IVR tab. 2 Select Conference Requires Chairperson and Terminate Conference after Chairperson Drops. 34 Polycom, Inc.
