6. Configure the Skype for Business LDAP server (Active Directory) to query for the
Skype for Business users' SIP URIs (see Configuring LDAP Servers on page 252).
7. Configure Call Setup Rules to perform LDAP queries in the Microsoft Active Directory
for the SIP URI of the caller (source) and called (destination) parties (see Configuring
Call Setup Rules on page 405). The device first needs to search the AD for the caller
or called number of the third-party endpoint device. For example, to search for a called
mobile number, the searched LDAP Attribute would be "mobile" set to the value of the
destination number (e.g., 'mobile=+' + param.call.dst.user). If the entry exists, the
query searches for the Attribute (e.g., ipPhone) where the SIP URI is defined for the
corresponding mobile user. If found, the query returns the Attribute's value (i.e., URI)
to the device (instructed using the special 'Condition' string "presence.dst" or
"presence.src"). This is the URI that the device uses as the Request-URI in the
PUBLISH message that it sends to the Skype for Business Server. The configuration
of the example used in this step is shown below:
Parameter Rule 1 Rule 2

8. Configure routing rules to route the calls in the network.
9. For SBC calls: Configure IP Groups to represent your call party entities, and assign
them the group of Call Setup Rules (Set ID) that you configured in Step 7 (above). For
Gateway calls: Assign the group of Call Setup Rules (Set ID) that you configured in
Step 7 (above) to your Tel-to-IP Routing rules (see Configuring Tel-to-IP Routing
Rules on page 509).
