AD-based Routing for Microsoft Teams or Skype for Business

Typically, companies wishing to deploy Microsoft® Teams or Skype for Business are faced with a complex, call routing dial plan when migrating users from their existing PBX or IP PBX to the Teams / Skype for Business environment. As more and more end-users migrate to the new voice system, dialing plan management and PBX link capacity can be adversely impacted. To resolve this issue, companies can employ Microsoft's Active Directory (AD), which provides a central database to manage and maintain information regarding user’s availability, presence, and location.

The device supports outbound IP call routing decisions based on information stored on the AD. Based on queries sent to the AD, the device can route the call to one of the following IP domains:

Teams / Skype for Business client - users connected to Teams / Skype for Business
PBX or IP PBX - users not yet migrated to Teams / Skype for Business
Mobile - mobile number
Private - private telephone line for Teams / Skype for Business users (in addition to the primary telephone line)

This section describes an earlier implementation for configuring AD-based routing. For new deployments, it's recommended to use Call Setup Rules (see Configuring Call Setup Rules). Call Setup Rules provide more flexibility and easier implementation. You can view examples in Examples of Call Setup Rules.
