Overview of this book

Lync 2013 is a product that enables users to IM, and have audio and video conferences, including multi-party video. The mobile client permits the use of all the features in every device with an access-from-everywhere logic. The company’s Active Directory users, SharePoint documents, and Exchange objects integrate with Lync to deliver most of the advanced features. Getting Started with Microsoft Lync Server 2013 will give you all the relevant information you need to enable voice features, select the best Lync client in different scenarios, make your Lync services available to the external users, empower the collaborative environment of Persistent Chat Server rooms, and to build an affordable unified communication system. Getting Started with Microsoft Lync Server 2013 will explore all the concepts you need to administer and plan a Lync 2013 environment in a short time, explaining the background mechanisms of the system.It begins with the deployment of a Lync frontend and SQL mirroring solution, including all the requirements and tips clearly laid out. It proceeds with the Front End pairing, mobility, and mediation server deployment with media bypass. It covers a core chapter about Enterprise Voice with a closing part on Persistent Chat and on clients with their characteristics. Getting Started with Microsoft Lync Server 2013 will give you all the relevant information you need to enable voice features, and will help to select the best Lync client in different scenarios.

Mediation server tasks


The Mediation server performs the following operations:

  • Identifying the type of network that a voice call will use

  • Selecting the best codec for the aforementioned network

  • Converting signals and media according to the previous points, such as translating SIP over TCP to SIP over TLS, translating media (G.711) on the gateway to RTAudio on CS, or for media traversal of NAT

Note

The most used codecs are: G711 (better quality but requires a network without packet loss) or RTAudio that is also able to work with a certain number of lost packets (RTAudio has a native error concealment module).

Talking about codecs, we should take a look at the document Network Bandwidth Requirements for Media Traffic (http://technet.microsoft.com/en-us/library/jj688118(v=ocs.15).aspx) that is really important for planning and understanding the bandwidth requirements for every single solution. If we are preparing a project we could also use the Lync 2010 and 2013 Bandwidth Calculator article at http...
