Implementing Enterprise Voice in Lync Server 2013 Microsoft 70-337

Enterprise Voice in Lync Server 2013 is a cornerstone technology for organizations aiming to unify their voice, video, and messaging infrastructure. Microsoft designed this system to replace traditional PBX environments with a software-defined, highly integrated solution that supports all aspects of voice communication. With Enterprise Voice, organizations can extend telephony features to desktops, mobile devices, and conference rooms, providing employees with a seamless communication experience regardless of location. Lync Server 2013 allows users to make peer-to-peer voice calls, group calls, conference calls, and access voicemail directly from the Lync client. In addition to replacing on-premises PBXs, Enterprise Voice provides advanced functionality such as call forwarding, delegation, simultaneous ring, voicemail integration, and integration with Exchange Unified Messaging.

Enterprise Voice depends on several critical components working together to ensure high reliability and quality of service. These components include Front End Servers, Mediation Servers, PSTN gateways, Session Border Controllers, and optionally, Edge Servers for external connectivity. Front servers host the user services and handle user authentication, presence, and call routing. Mediation Servers act as intermediaries between Lync and the PSTN, handling signaling and media translation. PSTN gateways allow Lync to connect to traditional telephony networks, while SBCs provide additional security and interoperability. The deployment architecture must be carefully designed to ensure proper load balancing, high availability, and redundancy for these components. Understanding the role and interaction of each component is essential for a successful Enterprise Voice implementation.

Planning for Enterprise Voice is the first and most critical step in the deployment process. Administrators must carefully review Microsoft’s planning documentation to understand the requirements for hardware, software, networking, and licensing. Hardware considerations include CPU, memory, and storage specifications for servers hosting Front End or Mediation roles. Networking considerations include ensuring adequate bandwidth, implementing Quality of Service policies, and understanding the effects of latency, jitter, and packet loss on voice quality. Licensing considerations include selecting the appropriate Lync Server 2013 edition, Client Access Licenses (CALs), and Enterprise Voice CALs to ensure compliance and full feature availability. Proper planning also involves determining the number of concurrent calls the environment must support, which directly affects server sizing, network capacity, and overall topology design.

Designing the Topology

The design of the Lync Server 2013 topology is a vital step that sets the foundation for all Enterprise Voice deployments. The topology defines server roles, their placement, and the interconnections between them. Microsoft provides the Topology Builder tool to help administrators visualize and define the network architecture. Topology Builder allows for designing complex deployments that span multiple central sites, branch sites, and external locations. Administrators can define Front End pools, Standard Edition servers, Mediation Server pools, Edge Servers, and optionally, Director servers. The tool also allows defining network sites, subnets, and network regions, which are essential for features like call admission control and media bypass. By modeling the entire environment, administrators can identify potential bottlenecks, redundancy plans, and ensure high availability.

When designing the topology, organizations must account for both central sites and branch sites. Central sites typically host core components like Front End pools and Mediation Servers, whereas branch sites may host Standard Edition servers or rely on central servers for services. Network connectivity between sites is critical, and administrators must ensure sufficient bandwidth and low-latency connections to maintain call quality. Site and region definitions within the topology determine how calls are routed internally, how media traffic flows, and how call admission control policies are applied. Network regions group sites with similar network characteristics, allowing Lync to optimize routing decisions and manage bandwidth efficiently.

Defining server roles and pools is another critical aspect of topology design. Front End pools handle user registration, presence, and call signaling, while Mediation Server pools interface with the PSTN. Standalone Mediation Server pools are often deployed for larger organizations or for scenarios requiring dedicated hardware to handle high call volumes. Collocated Mediation Servers, where the Mediation role is installed on the same server as the Front End, are suitable for smaller deployments or branch sites. Administrators must also plan for redundancy and high availability by deploying multiple servers in each pool and configuring failover mechanisms. Redundant servers ensure that services remain available even if a single server fails, minimizing downtime and maintaining business continuity.

Network Regions, Sites, and Subnets

Properly defining network regions, sites, and subnets is essential to ensure optimal routing, bandwidth management, and call quality. A network region is a logical grouping of sites with similar network characteristics, such as latency and bandwidth. Sites represent physical or logical locations within an organization, such as data centers or branch offices. Subnets are IP address ranges associated with each site, allowing Lync to determine the user’s location and apply appropriate policies. This structure enables features like call admission control, media bypass, and optimal media routing between sites.

Call admission control (CAC) is particularly important for managing network resources during periods of high traffic. CAC ensures that the network does not become overloaded with voice traffic, which could degrade call quality. By defining network regions and bandwidth policies, administrators can control how many concurrent calls are allowed between sites, preventing congestion and maintaining a consistent user experience. Media bypass is another feature that optimizes call routing by allowing media traffic to flow directly between endpoints instead of passing through the Mediation Server. This reduces latency, conserves server resources, and improves audio quality, particularly in geographically dispersed environments.

Prerequisites for Deployment

Before deploying Enterprise Voice, several prerequisites must be met to ensure a smooth and successful implementation.
