CHAPTER 20 SIP Definitions
◆
● IP-to-IP Routing table: A single routing rule is assigned the Call Setup Rule Set ID.
◆
■ Example 3: The example configures the device to route the incoming call according to whether
or not the source number of the incoming call also exists in the AD server. The device queries
the AD server for the attribute record, "telephoneNumber" whose value is the same as the
received source number (e.g., telephoneNumber=4064"). If such an attribute is found, the
device sends the call to Skype for Business; if the query fails, the device sends the call to the
PBX.

If the attribute record is found (i.e., condition is not met), the rule ends with a default exit
result of true and uses the first routing rule (Skype for Business). If the attribute record does
not exist (i.e., condition is met), the rule exits with a false result and uses the second
routing rule (PBX).
● IP-to-IP Routing table: Two routing rules are assigned with the same matching
characteristics. Only the main routing rule is assigned a Call Setup Rules Set ID.

◆
◆
◆
■ Example 4: The example enables routing based on LDAP queries and destination tags. The
device queries the LDAP server for the attribute record "telephoneNumber" whose value is the
destination number of the incoming call (e.g., "telephoneNumber=4064"). If the attribute-value
combination is found, the device retrieves the string value of the attribute record
"ofiSBCRouting" and creates a destination tag with the name of the retrieved string. The
destination tag is then used as a matching characteristics in the IP-to-IP Routing table.
