RealPresence DMA System Release Notes6.4What’s New in the Version 6.4 ReleaseVersion 6.4 of the Polycom RealPresence Distributed Media Application (DMA ) fixes the issuesidentified in the Resolved Issues section and offers the following new features and changes: Support for Polycom RealPresence Resource Manager Version 10.0 Microsoft Skype for Business MCU Affinity Integration with the Polycom RealPresence Collaboration Server MMCU and RDP ContentTranslator Scheduled Conference Support for Microsoft Office 365 Panoramic Layout Support for Skype for Business Other Changes API Additions and Changes Security Fixes in this ReleaseSupport for Polycom RealPresence ResourceManager Version 10.0This version of the RealPresence DMA system supports version 10.0 and higher of the Polycom RealPresence Resource Manager system. The RealPresence Resource Manager system is amanagement solution that provides unified management of the Polycom RealPresence Clariti solutionand video and audio endpoints. Unified management features include license management, monitoring,conference scheduling, and provisioning of Polycom video infrastructure products and both Polycom andthird-party endpoints within your environment.The RealPresence DMA system is available as part of the RealPresence Clariti offering. RealPresenceClariti customers who have a RealPresence Resource Manager system version 10.0 or later must use thesystem to license version 6.4 of the RealPresence DMA system. If you have not deployed aRealPresence Resource Manager system or if you have not upgraded your RealPresence ResourceManager system to version 10.0 or later, you must license your RealPresence DMA system using thePolycom RealPresence Platform Director system version 3.0 or later.RealPresence Clariti customers should consult with their Polycom representative to ensure they have thecorrect licensing information before upgrading.If you are not a RealPresence Clariti customer, you must use a license file or activation key code tolicense your product.Limitations and Requirements Two-server redundant configuration is not currently supported for RealPresence Clariti customersusing RealPresence DMA systems. If you use the RealPresence Platform Director system to manage your RealPresence DMA systeminstance, but the previous version of the instance was prior to version 6.1, delete the previousinstance before adding the new version 6.4 instance.Polycom, Inc.4

RealPresence DMA System Release Notes6.4 RealPresence Clariti customers cannot route calls or use the API until a license has beenconfigured from within the RealPresence Resource Manager system version 10.0 or later or theRealPresence Platform Director system version 3.0 or later.Microsoft Skype for Business MCU AffinityMicrosoft Skype for Business deployments can be geo-distributed. Polycom RealConnect conferences can occur on various Skype for Business AVMCUs deployed throughout the geography,based on the location of the Skype for Business front-end pool where a conference is located.Skype for Business MCU Affinity enables the RealPresence DMA system to select a Polycom MCU inproximity to the on-premise Skype for Business front-end pool that hosts a Polycom RealConnectconference. By configuring an MCU pool and MCU pool order that includes Polycom MCUs that are inproximity to a Skype for Business front-end pool, the RealPresence DMA system can select anappropriate MCU and then build a cascade link between the newly-created conference and the SkypeAVMCU.The ability the RealPresence DMA system now has to select a Polycom MCU in proximity to the SkypeAVMCU hosting the Polycom RealConnect conference can reduce call latency, traffic, and costs.This feature applies only to Polycom RealConnect conferences running on Skype for Business onpremise deployments. It is not applicable for Microsoft Office 365 environments or federateddeployments such as service providers.For configuration information, see the “External SIP Peers” and “Dial Rules” sections in the Polycom RealPresence Distributed Media Application (DMA ) System Operations Guide.Integration with the Polycom RealPresence Collaboration Server MMCU and RDP ContentTranslatorVersion 6.4 of the RealPresence DMA system supports a new MCU architecture. The Modular MCU(MMCU) with soft blades provides a scalable and extensible architecture for different media types. Eachsoft blade can provide one or more types of media to endpoints through a translator component within theblade.With version 8.7.1 and later of the Polycom RealPresence Collaboration Server, one of the media typesthat can be transcoded is Microsoft’s Remote Desktop Protocol (RDP), a content sharing technology usedby Lync , Skype for Business, and Office 365 clients. RDP translation enables content sharing betweenMicrosoft RDP-based endpoints and H.264 standards-based endpoints, without the need forindependently deployed and managed Polycom ContentConnect servers acting as gateways.The MMCU plus RDP translator architecture supports both conference-to-conference content (e.g.,Polycom RealConnect and similar scenarios) and single Lync or Skype for Business endpoints joiningVMR conferences, eliminating the need for a Lync or Skype client plug-in.For configuration information, see the “Conference Templates” section in the Polycom RealPresence Distributed Media Application (DMA ) System Operations Guide.5Polycom, Inc.

RealPresence DMA System Release Notes6.4Upgrading to version 8.7.1 or newer of the Polycom RealPresence Collaboration ServerTo use the MMCU with RDP translator capability, you must have version 8.7.1 or newer of thePolycom RealPresence Collaboration Server.Scheduled Conference Support for MicrosoftOffice 365 The RealPresence DMA system now supports conference scheduling for Microsoft Office 365 environments. The Office 365 solution includes the Polycom One Touch Dial App, a component thatenables video conferencing endpoints to join conferences through calendar invitations from MicrosoftOutlook and Exchange.Polycom One Touch Dial App supports other Office 365 and Skype-for-Business functionality, including Click to Join, where endpoints display a list of scheduled meetings and the user can click on one ofthem to automatically dial the conference Bring Your Own Device (BYOD), where a user has a smart-phone app or web page where they canpair themselves to an endpoint, view a list of meetings, click on one of them, and have the paireddevice dial into the conference.For both of these features, Polycom One Touch Dial App interacts with Office 365 to discover scheduledmeetings. Because One Touch Dial App is aware of the Office 365 meetings, it can use theRealPresence DMA system REST API to create a VMR with the necessary attributes to establish acombined Polycom and Office 365 conference (similar to RealConnect conferences).The RealPresence DMA system also supports conference scheduling for Office 365 environments withoutthe use of the One Touch Dial App. RealPresence DMA system administrators can manually createVMRs with an associated focus URI that links to the Office 365 conference.For configuration information, see the conference rooms sections in “Users and Groups” in the Polycom RealPresence Distributed Media Application (DMA ) System Operations Guide.Panoramic Layout Support for Microsoft Skypefor BusinessWith this version of the RealPresence DMA system and version 8.7.1 of the RealPresence CollaborationServer, Microsoft Lync 2013, Skype for Business, and Office 365 video conference participants will beable to see a continuous presence view of up to five Polycom participants, or all video streams from anITP telepresence room. The feature is available in Polycom RealConnect, Lync or Skype Meet Now, andEscalation conferences.When integrated with a Microsoft environment this feature enables a Polycom MCU to stream apanoramic layout from telepresence rooms or multiple non-Microsoft participants to Microsoft clients.This feature applies to on-premise and service provider deployment models.6Polycom, Inc.

RealPresence DMA System Release Notes6.4For configuration information, see the “Conference Templates” section in the Polycom RealPresence Distributed Media Application (DMA ) System Operations Guide.Upgrading to version 8.7.1 or newer of the Polycom RealPresence Collaboration ServerTo use panoramic layout with Microsoft environment conferences, you must have version 8.7.1or newer of the Polycom RealPresence Collaboration Server.Other ChangesVersion 6.4 of the RealPresence DMA system offers the additional enhancements described in thefollowing sections.Clear SNMP TrapsIn this version of the Polycom RealPresence DMA system, new SNMP traps are now sent when theunderlying Alert condition has been cleared.POLYCOM-DMA-MIB.mib reflects these new traps.Enhancements to Dialout ParticipantsIn the RealPresence DMA system, a conference room can be configured for preset dialout conferences.When someone dials in and starts a conference in one of these rooms, the RealPresence DMA systemdials out to the participants you have identified for the room.Version 6.4 of the RealPresence DMA system offers the following enhancements to configuring dialoutparticipants: Can specify connection encryption and the line rate Can specify optional extension digits for ISDN dial-out connections (audio-only) Can specify whether to automatically disconnect a participant when all other participants leave theconference (for example, when a dialout is to a recording device or audio conference bridge). Thisfeature prevents MCU-to-MCU dialouts from remaining open after the conference has ended. Can have any number of ISDN/PSTN participants (earlier versions only allowed one, audio-onlyISDN participant) Applies to both VMR preset dialouts and API dialouts.For configuration information, see the conference rooms sections in “Users and Groups” in the Polycom RealPresence Distributed Media Application (DMA ) System Operations Guide.7Polycom, Inc.

RealPresence DMA System Release Notes6.4Linux Root Password AdministrationIn this version of the RealPresence DMA system, enterprise and local administrators can change theLinux OS root password for the RealPresence DMA system without entering a shell interface. The rootpassword can be changed in the web user interface or via API.In normal system operations, RealPresence DMA system users, including Administrators, do not need toknow or use the Linux root password. However, if the root password has been compromised or ifcorporate security policies require changing all system passwords at certain intervals or after specificevents occur, the root password can be changed.Changing the Linux root password affects only the OS-level password, not the passwords ofRealPresence DMA system administrator accounts.For configuration information, see “Changing the Linux Root Password” in the Polycom RealPresence Distributed Media Application (DMA ) System Operations Guide.SIP Peer Inbound AuthenticationIn this version of the RealPresence DMA system, you can specify whether the system requiresauthentication credentials when an outbound call receives an inbound request. You can configure theRealPresence DMA system to always challenge or never challenge SIP peer inbound requests forauthentication credentials.This setting does not affect inbound calls, which are governed by the SIP settings for authorized andunauthorized ports and prefixes.For configuration information, see the “External SIP Peers” section in the Polycom RealPresence Distributed Media Application (DMA ) System Operations Guide.Local Log Forwarding AdditionsIn this version of the RealPresence DMA system, the following three additional logs can now beforwarded to a central log management server: secure.log messages.log audit.logFor configuration information, see “Configuring Logging Settings” in the Polycom RealPresence Distributed Media Application (DMA ) System Operations Guide.API Additions and ChangesThe RealPresence DMA system version 6.4 brings improvements to the API, as described in the followingsection. For more information about individual APIs, see the Polycom RealPresence API ResourceDocumentation included in the system’s online help.8Polycom, Inc.

RealPresence DMA System Release Notes6.4Changed APIsThe following list details changes to existing APIs in this release: plcm-conference-template-v7Added new fields to support Microsoft RDP content sharing and panoramic layout. plcm-mcu-v6Added support for Microsoft RDP content sharing. plcm-conference-room-v3Added new fields to support Polycom One Touch Dial App for Microsoft Office 365: Focus URI Registered Lync domain plcm-dma-supercluster-join-requestChanged the error returned if a valid but unavailable IP address is used for the host IP address in aPOST to the dma-supercluster API. A 504 error is now returned instead of a 408 error.Security UpdatesThe RealPresence DMA system version 6.4 includes the following updates that improve security: Version 6.4 does not allow weak cryptographic hash algorithms that are vulnerable to exploit. Aspart of this improved security, the RealPresence DMA system no longer supports certificates withan RSA key size less than 1024 bits in length. Unfortunately, some manufacturers of endpointshave not yet enhanced their software to support more secure encryption. As a result, TLSconnections made from the RealPresence DMA system to some endpoints will no longer work.Please refer to the Polycom Security Center for information about known and resolved securityvulnerabilities.9Polycom, Inc.

It also shows the typical performance capacities of thatdeployment.Minimum Deployment SettingsComponentMinimum Deployment SettingsVirtual 0 concurrent VMR calls150 concurrent point to point callsBecause of differences in hardware and VM environments, the performance information is provided forguidance purposes and does not represent a guarantee of any kind by Polycom.Features Not Supported with the Virtual EditionThe following are differences between the Appliance and Virtual Editions of the RealPresence DMAsystem: The Polycom RealPresence DMA system, Virtual Edition, does not support two-server redundantconfiguration as with the Appliance Edition. Polycom recommends using VMware High Availability(HA) to protect against host-level failures. See your VMware documentation for more information. Maximum Security Mode is not supported by the RealPresence DMA system, Virtual Edition.17Polycom, Inc.

RealPresence DMA System Release Notes6.4System and Network RequirementsFor the best reliability, deploy the Polycom RealPresence DMA system into an IP network with lowlatency and very little packet loss. In systems with Active Directory integration, the network between the RealPresence DMA systemand Active Directory should have less than 200ms round-trip latency and less than 4 percentround-trip packet loss. The network between clusters of a RealPresence DMA supercluster should have bandwidth above10 mbps, regardless of packet loss or latency; packet loss less than 1 percent if there is networklatency of 300ms or less (one-way) or network latency below 350ms (one-way) if there is no packetloss. The network between the RealPresence DMA system and all MCUs should have less than 200msround-trip latency and less than 2 percent round-trip packet loss. Since this network carries onlysignaling traffic (the RTP stream goes directly from the endpoint to the MCU), bandwidth is not anissue. The network between the RealPresence DMA system and video endpoints should have less than200ms round-trip latency and less than 6 percent round-trip packet loss. Computers used to access the management interface should have a 1280x1024 minimum displayresolution (wide screen, 1680x1050 or greater, recommended). Browser minimum requirements: Microsoft Internet Explorer 7.0, Mozilla Firefox 3.0, or GoogleChrome 11 (with Adobe Flash plugin, not built-in Flash support).Note: Cannot download files from Google ChromeDue to a known issue with Google Chrome, files, including logs, cannot be downloaded fromthe browser.Note: Latest version of Adobe Flash Player recommendedThe Polycom RealPresence DMA system’s management interface requires Adobe FlashPlayer. For stability and security reasons, Polycom recommends always using the latestversion of Flash Player.18Polycom, Inc.

RealPresence DMA System Release Notes6.4Products Tested with This ReleasePolycom RealPresence DMA systems are tested extensively with a wide range of products. The followinglist is not a complete inventory of compatible systems. Rather, it simply indicates the products that havebeen tested for compatibility with this release.Latest software versions recommendedPolycom recommends that you upgrade all of your Polycom systems with the latest softwareversions. Any compatibility issues may already have been addressed by software updat

In this version of the Polycom RealPresence DMA system, new SNMP traps are now sent when the underlying Alert condition has been cleared. POLYCOM-DMA-MIB.mib reflects these new traps. Enhancements to Dialout Participants In the RealPresence DMA system, a conference room can be configured for preset dialout conferences.
