CHAPTER 20 SIP Definitions

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.

Example 5: The example configures the device to perform an ENUM query with an ENUM

server to retrieve a SIP URI address for the called E.164 telephone number. The device then

replaces (manipulates) the incoming call's E.164 destination number in the SIP Request-URI

header with the URI retrieved from the ENUM server. The ENUM server's address is the

address configured in the 'Primary DNS' parameter for the "ITSP-450" IP Interface in the IP

Interfaces table.
