18.4.11.2 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 228.
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 18-24: LDAP Parameters for Microsoft Lync Server 2010
b. Configure the LDAP attribute names as desired.
3. Gateway application: Configure AD-based Tel-to-IP routing rules:
a. Open the Outbound IP Routing table (Configuration tab > VoIP menu > GW and
IP to IP > Routing > Tel to IP Routing). For more information, see Configuring
Outbound IP Routing on page 405.
b. Configure query-result routing rules for each IP domain (private, PBX / IP PBX,
Lync clients, and mobile), using the LDAP keywords (case-sensitive) for the
prefix destination number:
♦ 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 Tel call to the LDAP server, using
the value "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.
4. SBC application: 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 on page 564.
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
