The configured routing rule example is explained below:

Rule 1: Sends call to private telephone line (at 10.33.45.60) upon successful AD
query result for the private attribute.

Rule 2: Sends call to IP PBX (at 10.33.45.65) upon successful AD query result for the
PBX attribute.

Rule 3: Sends call to Skype for Business client (i.e., Mediation Server at 10.33.45.68)
upon successful AD query result for the Skype for Business attribute.

Rule 4: Sends call to user's mobile phone number (to PSTN through the device's IP
address at 10.33.45.100) upon successful AD query result for the Mobile attribute.

Rule 5: Sends call to IP address of device (10.33.45.80) if AD query failure (e.g., no
response from LDAP server or attribute not found).

Rule 6: Sends query for original destination number of received call to the LDAP
server.

Rule 7: Alternative routing rule that sends the call of original dialed number to IP
destination 10.33.45.72. This rule is applied in any of the following cases
•
LDAP functionality is disabled.
•
LDAP query is successful but call fails (due to, for example, busy line) to all the
relevant attribute destinations (private, Skype for Business, PBX, and mobile),
and a relevant SBC Alternative Routing Reason (see Configuring SIP Response
Codes for Alternative Routing Reasons on page 476) has been configured.
Once the device receives the original incoming call, the first rule that it uses is Rule 6,
which queries the AD server. When the AD replies, the device searches the table, from the
first rule down, for the matching destination phone prefix (i.e., "PRIVATE:, "PBX:", "OCS:",
"MOBILE:", and "LDAP_ERR:"), and then sends the call to the appropriate destination.
