18.4.11 Active Directory-based Routing for Microsoft Lync
Typically, enterprises wishing to deploy the Microsoft® Lync™ Server are faced with a
complex, call routing dial plan when migrating users from their existing PBX or IP PBX to
the Lync Server platform. 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, enterprises 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:

Lync client - users connected to Lync Server through the Mediation Server

PBX or IP PBX - users not yet migrated to Lync Server

Mobile - mobile number

Private - private telephone line for Lync users (in addition to the primary telephone
line)
18.4.11.1 Querying the AD and Routing Priority
The device queries the AD using the initial destination number (i.e., called number). The
query can return up to four user phone numbers, each pertaining to one of the IP domains
(i.e., private number, Lync number, PBX / IP PBX number, and mobile number). The
configuration parameters listed in the table below are used to configure the query attribute
keys that defines the AD attribute that you wish to query in the AD:
