Chapter 32. Planning for Voice Deployment

Spending time to plan and prepare for a Lync Enterprise Voice deployment is an important step for organizations, and will have a significant impact in determining whether the deployment is a success.

Be sure to review the concepts found in Chapter 17, “Lync Telephony and Voice Integration,” before continuing in this chapter. Many of the discussions in this chapter assume that an integration method has been discussed and selected.

This chapter discusses what details to consider when planning for Lync Enterprise Voice, and how those decisions can affect other aspects of the deployment. Dial plans, steering codes, and normalization rules are covered, along with how to apply those concepts to a trunk configuration. Also discussed is how to plan for different classes of service within voice policies, and how least cost routing and tail-end hop off factor into routing.

The different options available for providing voice resiliency are discussed, and the differences between a Survivable Branch Server (SBS) and a Survivable Branch Appliance (SBA) are covered in this chapter. Lastly, planning concepts around Call Admission Control, Media Bypass, E911, and Response Groups is included.
