14.1.3 Active Directory based Tel-to-IP Routing for Microsoft Lync
Typically, enterprises wishing to deploy Microsoft® Lync™ Server 2010 (formerly known as
Office Communication Server 2007) are faced with a complex, call routing dial plan when
migrating users from their existing PBX or IP PBX to the Lync Server 2010 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 Tel-to-IP call routing decisions based on information stored on the AD.
Based on queries sent to the AD, the device can route the Tel call to one of the following IP
domains:

Lync client (formally OCS) - users connected to Lync Server 2010 through the
Mediation Server

PBX or IP PBX - users not yet migrated to Lync Server 2010

Mobile - mobile number

Private - private telephone line for Lync users (in addition to the primary telephone
line)
14.1.3.1 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 / OCS number, PBX / IP PBX number, and mobile number).
