15.4.11.2 Configuring AD-Based Routing Rules
The following procedure describes how to configure outbound IP routing based on LDAP
queries.
To configure LDAP-based IP routing for Lync Server:
1. Configure the LDAP server parameters, as described in 'Configuring LDAP Servers'
on page 201.
2. Configure the AD attribute names used in the LDAP query:
a. Open the Advanced Parameters page (Configuration tab > VoIP menu > SIP
Definitions > Advanced Parameters).
Figure 15-28: LDAP Parameters for Microsoft Lync Server 2010
b. Configure the LDAP attribute names as desired.
3. Configure AD-based IP-to-IP routing rules:
a. Open the IP-to-IP Routing Table page (Configuration tab > VoIP menu > SBC >
Routing SBC > IP-to-IP Routing Table). For more information, see Configuring
SBC IP-to-IP Routing Rules.
b. Configure query-result routing rules for each IP domain (private, PBX / IP PBX,
Lync clients, and mobile), using the LDAP keywords (case-sensitive) in the
Destination Username Prefix field:
♦ PRIVATE: Private number
♦ OCS: Lync client number
♦ PBX: PBX / IP PBX number
♦ MOBILE: Mobile number
♦ LDAP_ERR: LDAP query failure
c. Configure a routing rule for routing the initial call (LDAP query) to the LDAP
server, by setting the 'Destination Type' field to LDAP for denoting the IP address
of the LDAP server.
d. For alternative routing, enable the alternative routing mechanism and configure
corresponding SIP reasons for alternative routing. For this feature, alternative
routing starts from the table row located under the LDAP query row.
The table below shows an example for configuring AD-based SBC routing rules in the IP-
to-IP Routing Table:
