33. Resiliency Architecture Each user has a “Primary Registrar Pool”. Each Registrar Pool can have a “Backup Registrar Pool” Branch Users register with the SBA Registrar unless it is unavailable Backup Registrar heart-beats Primary Registrar.

58. Call Admission Control New Policy Server role introduced in Lync Server 2010 to support CAC Admins configure logical sites based on groupings of subnets Enforce policies on links between sites Bandwidth available for audio, video Maximum bandwidth allowed per session Rerouting behavior when bandwidth limited exceeded Seamless support for roaming Microsoft Lync 2010 users on moving between different sites Allows Internet to be used for overflow of traffic Avoid PSTN call charges Support alternate path & failover of video sessions http://technet.microsoft.com/en-us/library/ff731056.aspx
59. Monitoring Server Monitoring Server captures both call detail record (CDR) and Monitoring Server data, which incorporates file transfer, application sharing, and remote assistance Instant Messaging archiving is solely covered in Archiving Server Works with both Standard Edition or Enterprise Edition Pool (any supported topology) SQL Server reporting Services (for detailed reports) 64-bit versions of SQL Server Standard or Enterprise Edition of SQL Server 2005 with Service Pack 3 Standard or Enterprise Edition of SQL Server 2008 with Service Pack 1

85. Data Center Voice ResiliencyFailover to Backup Data Center Lync Server pools operate as separate systems. Client DNS SRV request discovers one or multiple Lync Server Pools. That Lync Server Pool directs client to primary and backup SIP registrar. Client connects to Backup if connecting to Primary Registrar Pool fails. Limited feature set available on failover. Enable/Disable automatic failover, configurable failover interval. Automatic Failback, configurable failback interval. If Primary Data Center cannot be restored: Restore Central Management Server in backup datacenter. Restore other services including Presence, Conferencingby “moving” users to other Pool.
86. Backup Registrar Berlin Data Center Edge Server Lync Server Director Lync Server Pool One AD DS & DNS WAN Lync Server Pool Two Edge Server (5) Client DNS SRV request. Example: DNS SRV for _sipinternaltls._tcp.contoso.com DNS SRV Response includes: Lync Director Pool.contoso.com:5061, Priority=0, Weight=10, LSPool2.contoso.com:5061, Priority=1 , Weight=10 Client connects via TLS to Lync Server Director Pool. Sends SIP Register. Authenticates. Lync Server Director Pool redirects client. SIP 301 includes Primary & Backup Registrar pool If Primary Registrar Pool is available, client connects and registers with it If unavailable, client connects and registers with Backup Registrar Pool (Lync Pool 2) (3) (4) (2) (1) Data Center Voice ResiliencyFailover to Backup Data Center (Discovery) (6) Singapore Data Center
87. Private Line LyncServer introduces support for private line Single SIP URI, single Exchange mailbox, single presence source Receipt of inbound calls on private DID to same SIP URI Private lines carry many of the same features Call pickup & park work as expected Simultaneous ringing & call deflection on primary line carry to private line Private lines are different: Available for inbound calls only Overrides delegation, call forwarding, do-not-disturb and other routing options – private calls are always going to go through Calls to a private line have a distinctive ring & “toast” pop-up
88. Malicious Call Trace Lync provides the end-user the capability of tagging theprior call as a malicious call. Supported in Communicator, Communicator Phone Edition& Attendant Console. Tagging is reflected in the backend CDR database, enabling the Lync Server administrator to take action on the call.
89. Analog Device Management Physical connectivity of Analog devices (FXS) provided by GW partners All routing and policy enforcement for Analog devices centralized in Lync Server – eliminates the need to manage GWs as “mini-PBX” Lync Server Call Detail Record (CDR) infrastructure used to track usage Optimized routing allows Fax call routing through Lync Server 2010 without terminating Media PSTN Fax FXS FXS Gateway ATA Lync Analog Device
90. Caller ID Presentation Controls Admins can natively control what Caller ID is presented to receiving party (PSTN/PBX): Per user/group controls to suppress/alter calling party number Granular controls based on caller and destination number: Alice calls an external PSTN number, caller ID is presented as +1 425 555 0100 Alice calls an internal PBX number, caller ID is presented as +1 425 555 2302 Override for “simultaneous ringing”: Bob calls Alice, who has simultaneous ringing configured to her mobile number; Bob’s caller-id is presented Calling Name Display feature allows display name to ingress/egress Also Available for OCS 2007 R2 through KB
91. Voice Policy Enhancements Provide admins flexibility to control user voice entitlements Call Forwarding Delegation Call Transfer Call Park Simultaneous Ringing Team Call PSTN Rerouting BW Policy Override Malicious Call Tracing Useful to address Common Area Device requirements

93. Audio/Video Bandwidth Controls End User maximum allowed bandwidth per modality Applied whether or not bandwidth is available Configured via in-band provisioning at sign-in Wide-area network (WAN) link bandwidth policies (aka Call Admission Control (CAC)) Applied dynamically when session crosses network link with policy set Limits to maximum allowed level when bandwidth available Re-routesor fails session when bandwidth not available
94. Network QoS– DiffServ (DSCP) When Right Provisioning not possible and so Constrained WAN Links (pair with WAN bandwidth Policies) Audio prioritization already deployed for other Voice over Internet Protocol (VoIP) solution Example “Fully Managed” Network Deployment
95. SBA - DeploymentSimple, Easy, Repeatable Active Directory Computer Add SBA to the Topology. Move Users to the SBA. Lync Admin (Data Center) Enable CS Replication. SBA downloads topology & configuration. Request & Assign Certs. Join to Domain & complete SW configuration. Start CS services. Finish GW Config and test PSTN Connectivity with temp user account.

Varje Registrar har sin egen SQL express DBAnvändare lastbalanseras av registratorn Man kan installera registratorer på lokal kontor
Varje användare har en primär och en backup pool som dom registrerar sig mot.Branch användare registrerar sig alltid mot en SBA i de fall en sådan finns. Klienter hittar sin pool via DNS recordsWebticket - Certifikat tillsammans med lösenord används ifrån en egen CA på lync servern detta ger en så kallad webticketHeartbeat mellan servrar – om heartbeat slutar så kommer backupregistratorn börja att acceptera anslutningar
DNS baserad last balansering HW lastbalanserare krävs fortfarande för HTTP trafik, tex mötesinnehåll, OBS NLB är inte supporteratDrainingClientcashar namn och ip till alla lync servrar, vilket även minnimeraranslutningstid.
Upp till 25 anv, liten localgateway eller mobil som backup.500 anv = SBA1000+ SBS eller Lync SE+GW
IM,Appsharing, Online möten fungerar ej.Response Groups fungerar inte heller.Däremot så kommer man ut på PSTN och kan på det sättet nå många av de tjänsterna. Ex voice mail. Audio conferencing.

När möjlighet finns försöker alltid lync klienten att prata direkt med endpointen på andra sidan eller så nära den som möjligt. Den väljer även codec baserat på samtalstyp så i ett PSTN samtal så kommer den välja G711Vissa SIP trunk leverantörer tillåter inte att klienter från olika IPn pratar direkt med dom varpå det kräver en separat mediation server.Bypass to a media gatewayGateways qualified for Lync 2010 will be supported for bypass.G.711 over SRTP direct from Communicator to Gateway.Bypass to select IP-PBXsKeep in-branch media between IP-PBX and Communicator local without deploying Mediation Server on site.May require Media Termination Point or similar – testing underway.G.711 direct from OC to Cisco Unified Communications Manager (CUCM) Media Termination Point (MTP) to Cisco IP phone.SIP TrunkingSupport TBD – Carrier SBCs generally don’t accept connections from any client.Media Bypass of Mediation ServerWhenever possible media for calls egressing to the PSTN will flow directly to upstream device without traversing Mediation ServerApplies where media can stay local to a capable next hop - a network site or branch officeDoes not apply where media is not localSignaling continues to traverse Mediation Server roleConsolidation of most Mediation resources at the Data Center.Mediation could be on a Front End, in a SBA, or standaloneLow CPU intensity enables running Mediation role on FE & Appliance
