Stay Connected with Mobile Clients: Using mobile clients for Lync, information workers can view colleagues' availability and select the best way to communicate—initiating instant messaging (IM), e-mail, or a phone call. In addition, workers using their mobile device provide accurate availability status back to other users when using mobile clients for Lync.

Connect to Conferences with a Single Click: Mobile clients for Lync can enable information workers to join a Lync conference with a single click of a button, without requiring users to dial conference numbers and enter long numeric passcodes.

Connect with Others Using a Single, Consistent Identity: A single telephone number can be used across desk phone, PC, and mobile phone. Outbound calls from a mobile device with a Lync client can enable the use of a single identity and phone number, making it easier to recognize calls from the Lync mobile client by colleagues, partners, customers, and personal contacts.

Connect More Securely: With communication channel encryption, transport layer security (TLS) support, and perimeter/internal network protection, your communications experience is safer no matter where you are or what network you use.

Connect Using Your Favorite Smartphone: Mobile clients for Lync, developed by Microsoft, smartphone vendors, or development partners, will be available for all major smartphone platforms. Microsoft-developed Lync clients will be available for Windows Phone 7 and iPhone, jointly developed clients will be available for Nokia phones, and partner-developed clients will be available for other smartphone platforms.
