Lync and the mobile
Some people in this room, might think that Lync is not for them?
One reason might be the missing mobile story?
And that's true, for now, but….

Lync and the mobile story
Mobile clients for Lync, developed by Microsoftwill be available for all major smartphone platforms.
Microsoft-developed Lync clients will be available for Windows Phone 7 and iPhone

Mediation Server Capacity (Mediation Server Collocated with Standard Front End Server)

Stand-alone Mediation Server Capacity: 70% Internal Users, 30% External users

Voice high availability design
Each registrar has its SQL Express DB
All user end points register with same registrar
Users are load balanced by Registrars using a Distributed Hash Algorithm
Registrar can be installed in remote locations

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.

More Resiliency enhancements
DNS Based Load Balancing for Internal Pools
Ability to drain a “server” before taking the server down

Conferencing Maximums
If you have fewer than 10,000 users at a site, and typical A/V usage, you can collocate the A/V Conferencing Server role with your Front End Servers.
More than 10,000 users, deploy A/V Conferencing Server separately
Each A/V Conferencing Server can support about 1,000 concurrent A/V conference users
Max 250 participants in a conference

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.

Client DNS SRV request. Example: DNS SRV for _sipinternaltls._tcp.contoso.com
DNS SRV Response includes:

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)

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

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.

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

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
