Using Lync Server 2010

When you depl
oy cumulative update for Lync Server 2010: November 2011, you can deploy the
mobility feature to provide Microsoft Lync 2010 functionality on mobile devices. This section
provides
a

-

about the mobility feature
service
and how to plan for

deploying it.

Mobility Features and Capabilities

in Lync Server 2010

The mobility feature in Lync Server 2010 supports Lync functionality on mobile devices. When
you deploy the Microsoft Lync Server
2010 Mobility Service, users can use supported Apple iOS

for iPhone and iPad
, Android

smartphone (Android tablet not supported)
, Windows Phone, or
Nokia
Symbian
mobile devices to perform such activities as sending and receiving instant
messages, viewing co
ntacts, and viewing presence. In addition, mobile devices support some
Enterprise Voice features, such as join a conference, Call via Work, single number reach, voice
mail, and missed calls.

Tip:

With single number reach, a user receives calls on a mobil
e phone that were dialed to the
work number. With Call via Work, the user places an outbound call from a mobile phone
by using a work phone number instead of the mobile phone number. To use Call via
Work, a user can either dial directly from the mobile pho
ne or use dial
-
out conferencing.
With dial
-
out conferencing, the user in effect requests the Mobility Service to make the
call for them. The server initiates the call and then calls the user back on the mobile
phone. When the user answers, the server compl
etes the call by dialing the other party.
By using Call via Work, users can maintain their work identity during a call, which means
that the call recipient does not see the caller's mobile number, and the caller avoids
incurring outbound calling charges.

Note:

Not all features work exactly the same on all mobile devices. For
specific
details about
features supported on mobile devices
,
supported devices and operating systems,
see
Pla
nning for Mobile Clients

on Microsoft TechNet
.


When you use the Microsoft Lync Server 2010 Autodiscover Service along with the Mobility
Service, mobile applications can automatically locate Lync Server Web Services without requiring
users to manually ent
er the URLs in their device settings. Manually entering URLs in mobile
device settings is also supported, primarily for troubleshooting purposes.

The mobility feature also supports
push notifications

for mobile devices that do not support
applications runn
ing in the background. A push notification is a notification that is sent to a mobile
device about an event that occurs while a mobile application is inactive. Examples of events that
can result in a push notification are missed instant messaging (IM) invi
tations or missed calls.

The Mobility Service, Autodiscover Service, and support for push notifications are provided in the
cumulative update for Lync Server 2010: November 2011.

Topologies and Components for Mobility

To support Lync mobile applications on

mobile devices, the cumulative update for Lync Server
2010: November 2011 provides three new services. This section briefly describes these
components and identifies the Lync Server 2010 topologies that support mobility.

Mobility Components

The new servic
es that support mobility are as follows:



Microsoft Lync Server 2010 Mobility Service

This new service supports Lync 2010
functionality, such as instant messaging (IM), presence, and contacts, on mobile devices.

Note:

For a complete list of supported

Lync features on mobile devices, see Mobile Client
Comparison Tables

in the Lync Mobility Guide
.

The Mobility Service is installed on every Front End Server in each pool that is to support
Lync functionality on mobile devices.

When you install the Mobilit
y Service, a new virtual directory (Mcx) is created under both the
internal website and the external website on your Front End Servers.



Microsoft Lync Server 2010 Autodiscover Service

This new service identifies the
location of the user and enables mobile devices to locate resources, such as the internal and
external URLs for Lync Server Web Services and the URL for the new Mobility Se
rvice,
regardless of network location. Automatic discovery uses hardcoded host names
(lyncdiscoverinternal for users inside the network and lyncdiscover for users outside the
network) and the SIP domain of the user. It supports client connections using eit
her HTTP or
HTTPS.


6

The Autodiscover Service is installed on every Front End Server and on every Director in
each pool that is to support Lync functionality on mobile devices. When you install the
Autodiscover Service, a new virtual directory (Autodiscover)

is created under both the internal
website and the external website on both Front End Servers and Directors.



Microsoft Lync Server 2010 Push Notification Service

This service is a cloud
-
based
service that is located in the Lync Online datacenter. When

the Lync mobile application on a
supported Apple iOS device or Windows Phone is inactive, it cannot respond to new events,
such as a new instant messaging (IM) invitation, a missed instant message, a missed call, or
voice mail, because these devices do no
t support mobile applications running in the
background. In such a case, a notification, called a
push notification
, for the new event is sent
to the mobile device. The Mobility Service sends the notification to the cloud
-
based Push
Notification Service, w
hich then sends the notification either to the Apple Push Notification
Service (APNS) (for supported Apple iOS devices) or to the Microsoft Push Notification
Service (MPNS) (for Windows Phone), which sends it on to the mobile device. The user can
then touc
h the notification on the mobile device to activate the application.

Note:

The Lync mobile application can run in the background on Android and Nokia
devices, so push notifications are not required for these devices.


The following diagram illustrates ho
w the Push Notification Service fits in with a Lync Server 2010
topology.

Mobility Capabilities in
Office 365 and
Lync Online

Microsoft® Lync™ Online is a next
-
generation cloud communications service based on Lync
Server 2010 technologies

and available as part of the
Office 365™ online service
. Lync Online
provides intuitive communications capabilities across presence, instant messaging, PC
-
to
-
PC
audio/video calling, and a rich online meeting ex
perience including PC
-
audi
o, video and web

support

Lync
2010
on mobile devices. Users can use supported
Apple iOS for iPhone and iPad, Android smartphone (Android tablet
is
not supported), Windows
Phone, or N
okia Symbian mobile devices to perform such activities as sending and receiving
instant messages, viewing contacts, and viewing presence.


The Lync Online service is already pre
-
configured for access from the Lync 2010 mobile clients.

However, when using

your own domain name with Lync Online, a Domain Name Service (DNS)
CNAME record entry is needed to enable Lync mobile clients to auto
-
discover the Lync Online
service. For specific DNS configuration, please see the

Office 365 support article “Set
-
up for
Lync Mobile Devices
.



Tip:

The ‘Join Conference’ feature is supported when Lync Online is configured
with
an
authorized Office 365 audio confere
ncing provider. For more information, please refer to
the
Office 365 support article regarding using and authorized audio conferencing
providers with the Lync Online

service
.




Note:
Since the Lync Online service does not include the Enterprise Voice functionality

t
he ‘Call
-
via
-
Work’ feature

of the Lync mobile client
is not supported with Lync Online.
